Upon oral administration, lartesertib targets and binds to ATM, thereby inhibiting the kinase activity of ATM and ATM-mediated signaling. This prevents DNA damage checkpoint activation, disrupts DNA damage repair, induces tumor cell apoptosis, and leads to cell death of ATM-overexpressing tumor cells. In addition, by preventing DNA damage repair, M4076 sensitizes tumor cells to chemo- and radiotherapy and increases their anti-tumor activity. ATM, a serine/threonine protein kinase upregulated in a variety of cancer cell types, is activated in response to DNA damage and plays a key role in DNA-strand repair.
- Lasix
- (Other name for: furosemide)
- lasmotinib
- An orally bioavailable inhibitor of checkpoint kinase 2 (chk2), with potential antineoplastic and chemopotentiating activities. Upon oral administration, lasmotinib binds to and inhibits the activity of chk2, which may prevent the repair of DNA damage caused by DNA-damaging agents. This may result in tumor cell apoptosis and potentiate the antitumor efficacies of various chemotherapeutic agents. Chk2, an ATP-dependent serine-threonine kinase, is a key component in the DNA replication-monitoring checkpoint system and is activated by double-stranded breaks (DSBs); activated chk2 is overexpressed by a variety of cancer cell types.
- lasofoxifene
- A non-steroidal, naphthalene-derived, third-generation selective estrogen receptor modulator (SERM) with potential antineoplastic and anti-osteoporotic activities. Upon oral administration, lasofoxifene selectively binds to both estrogen receptor alpha (ERalpha; ESR1) and estrogen receptor beta (ERbeta; ESR2) with high affinity and mimics the effects of endogenous estradiol with varying agonist and antagonist effects in ER-expressing tissues. Blockade of ERalpha by lasofoxifene may potentially inhibit estrogen-dependent cancer cell proliferation in ER-expressing cancers. Lasofoxifene may also bind to the certain mutant forms of ERalpha, including the Y537S ESR1 mutant, making it potentially useful in the treatment of tumors that have acquired resistance to other ER-targeting agents.

- laventatug tivedotin
- An antibody-drug conjugate (ADC) composed of laventatug, a humanized monoclonal antibody directed against solute carrier family 39 zinc transporter member 6 (SLC39A6; LIV-1; ZIP6) that is conjugated, via a linker, to the cytotoxic agent monomethyl auristatin E (MMAE), with potential antineoplastic activity. Upon administration and binding to LIV-1-positive tumor cells, laventatug tivedotin enters the tumor cell lysosome through endocytosis, and releases MMAE. MMAE binds to and inhibits tubulin polymerization, which may result in G2/M phase cell cycle arrest and apoptosis in LIV-1-expressing tumor cells. LIV-1, a multi-pass transmembrane protein and zinc transporter, is expressed in several types of solid tumors and plays a key role in tumor cell progression, proliferation and metastasis. The conjugation method and linkage system prevent MMAE from separating from the antibody during circulation, thereby limiting off target toxicity.
- Lazanda
- (Other name for: fentanyl citrate pectin-based nasal spray)
- Lazcluze
- (Other name for: lazertinib mesylate hydrate)
- lazertinib mesylate hydrate
- The hydrated mesylate salt form of lazertinib, an orally available third-generation, selective inhibitor of certain forms of the epidermal growth factor receptor (EGFR) with activating mutations, including the resistance mutation T790M, exon 19 deletions (Del19), and the L858R mutation, with potential antineoplastic activity. Upon oral administration, lazertinib specifically and irreversibly binds to and inhibits selective EGFR mutants, specifically EGFR exon 19 deletions and exon 21 L858R substitution mutations. This prevents EGFR mutant-mediated signaling and leads to cell death in EGFR mutant-expressing tumor cells. In addition, lazertinib penetrates the blood-brain barrier (BBB). As this agent shows minimal activity against wild-type EGFR (wtEGFR), systemic toxicity is minimal as compared to non-selective EGFR inhibitors. EGFR, a receptor tyrosine kinase (RTK) mutated in many tumor cell types, plays a key role in tumor cell proliferation and tumor vascularization.

- ledipasvir
- An orally available inhibitor of the hepatitis C virus (HCV) non-structural protein 5A (NS5A) replication complex, with potential activity against HCV. Upon oral administration and after intracellular uptake, ledipasvir binds to and blocks the activity of the NS5A protein. This results in the disruption of the viral RNA replication complex, blockage of HCV RNA production, and inhibition of viral replication. NS5A, a zinc-binding and proline-rich hydrophilic phosphoprotein, plays a crucial role in HCV RNA replication. HCV is a small, enveloped, single-stranded RNA virus belonging to the Flaviviridae family; HCV infection is associated with the development of hepatocellular carcinoma (HCC).
- ledipasvir mixture with sofosbuvir
- A tablet containing a fixed dose combination of ledipasvir, an inhibitor of the hepatitis C virus (HCV) non-structural protein 5A (NS5A) replication complex, and the prodrug sofosbuvir, an inhibitor of HCV NS5B polymerase, with activity against HCV. Upon oral administration of ledipasvir/sofosbuvir and intracellular uptake, ledipasvir binds to and blocks the activity of the NS5A protein. This results in the disruption of the viral RNA replication complex, blockage of HCV RNA production, and inhibition of viral replication. Sofosbuvir is converted to its active triphosphate form, and competes with uridine triphosphate for incorporation into RNA, thereby inhibiting NS5B polymerase and preventing viral replication. This may eradicate HCV and prevent HCV-mediated tumorigenesis. NS5A, a zinc-binding and proline-rich hydrophilic phosphoprotein, plays a crucial role in HCV RNA replication. The HCV NS5B protein, an RNA-dependent RNA polymerase, is essential for the replication of the viral HCV RNA genome. HCV is a small, enveloped, single-stranded RNA virus belonging to the Flaviviridae family; HCV infection is associated with the development of certain tumors.
- leflunomide
- A derivative of isoxazole used for its immunosuppressive and anti-inflammatory properties. As a prodrug, leflunomide is converted to an active metabolite, A77 1726, which blocks dihydroorotate dehydrogenase, a key enzyme of de novo pyrimidine synthesis, thereby preventing the expansion of activated T lymphocytes. This agent also inhibits various protein tyrosine kinases, such as protein kinase C (PKC), thereby inhibiting cell proliferation.
- lemzoparlimab
- A human monoclonal antibody targeting the human cell surface antigen CD47, with potential phagocytosis-inducing and antineoplastic activities. Upon administration, lemzoparlimab preferentially binds to a unique epitope of CD47 on tumor cells. This blocks the interaction of CD47 with signal regulatory protein alpha (SIRPalpha), an inhibitory protein expressed on macrophages and dendritic cells (DCs), which prevents CD47/SIRPalpha-mediated signaling and abrogates the CD47/SIRPalpha-mediated inhibition of phagocytosis. This induces pro-phagocytic signaling mediated by the binding of calreticulin (CRT), which is specifically expressed on the surface of tumor cells, to low-density lipoprotein (LDL) receptor-related protein (LRP), expressed on macrophages, which results in macrophage activation and the specific phagocytosis of tumor cells. Additionally, blocking CD47 signaling activates an anti-tumor T-lymphocyte immune response and T-cell-mediated killing of CD47-expressing tumor cells. CD47, also called integrin-associated protein (IAP), is a tumor-associated antigen (TAA) expressed on normal, healthy hematopoietic stem cells (HSCs) and overexpressed on the surface of a variety of cancer cells. Expression of CD47, and its interaction with SIRPalpha, leads to the inhibition of macrophage activation and protects cancer cells from phagocytosis, which allows cancer cells to proliferate. TJC4, compared to other anti-CD47 monoclonal antibodies, is designed to minimize inherent binding to normal red blood cells (RBCs), which may results in a more advantageous hematologic safety profile.
- lenalidomide
- A thalidomide analog with potential antineoplastic activity.

Additionally, lenalidomide promotes G1 cell cycle arrest and induces apoptosis in malignant cells.
- lenapenem
- A broad-spectrum, carbapenem antibiotic with bactericidal activity. Lenapenem binds to penicillin binding proteins (PBPs) located on the bacterial cell wall, thereby inhibiting the final transpeptidation step in the synthesis of peptidoglycan, an essential component of the bacterial cell wall. This inhibition weakens the bacterial cell wall and leads to lytic cell death in a wide range of Gram-positive and Gram-negative aerobic and anaerobic pathogens.
- lenograstim
- A glycosylated form of a recombinant therapeutic agent which is chemically identical to or similar to an endogenous human granulocyte colony-stimulating factor (G-CSF).

- Lenti-D/ABCD1-transduced autologous hematopoietic stem cells
- Autologous CD34+ hematopoietic stem cells transduced with Lenti-D lentiviral vector encoding the human ATP-binding cassette, sub-family D, member 1 (ABCD1) cDNA, for the potential treatment of childhood cerebral adrenoleukodystrophy (CCALD). Upon administration of the lenti-D/ABCD1-transduced autologous hematopoietic stem cells, the cells proliferate, and some travel to the brain and differentiate into microglial cells. The expressed ABCD1 restores the function of ALD protein (ALDP) and aids in the treatment of CCALD. In CCALD, the ABCD1 gene is mutated, leading to the inability of patients to metabolize very long chain fatty acids in cells of the brain.
- LentiGlobin BB305 Drug Product
- (Other name for: betibeglogene autotemcel)
- LentiGlobin BB305 lentiviral vector-transduced autologous SCD CD34+ hemaptopoietic stem cells bb1111
- A preparation of autologous, CD34-positive hematopoietic stem cells (HSCs), obtained from patients with sickle cell disease (SCD), transduced ex vivo with the BB305 recombinant replication-defective, self-inactivating lentiviral vector (LVV) encoding for an engineered, modified form of human beta-globin (hemoglobin-beta, HBB) gene, beta-A-T87Q (b-A-T87Q), in which the threonine (Thr; T) at position 87 has been substituted with glutamine (Gln; Q), with potential to restore beta-globin expression and function in SCD patients. Autologous CD34-positive stem cells are isolated from the patient's own bone marrow and the cells are transduced with the lentiviral vector. Upon re-infusion of autologous bb1111 back into the patient, these cells express the non-sickling b-A-globin protein b-A-T87Q-globin, thereby allowing the body to make anti-sickling hemoglobin, HbA-T87Q, and thus normal, healthy red blood cells (RBCs). Beta-globin, the beta-chain of the most common form of hemoglobin, is encoded by the HBB gene; mutations in this gene prevent normal beta-globin production and are associated with SCD. The b-A-T87Q form of beta-globin has increased anti-sickling activity compared to the wild type protein.
- lentivirus vector CCR5 shRNA/TRIM5alpha/TAR decoy-transduced autologous CD34-positive hematopoietic progenitor cells
- Autologous, CD34-positive hematopoietic progenitor cells (HPCs) transduced with a lentiviral vector encoding three anti-human immunodeficiency virus (HIV) genes: a short hairpin RNA (shRNA) that targets human chemokine receptor 5 (CCR5), a human/rhesus macaque chimeric tripartite motif-containing protein 5 alpha isoform (TRIM5alpha), and a TAT activation response (TAR) decoy, as well as a pre-selective cell-surface marker, which is a truncated and mutated form of human CD25, used to potentially provide resistance against human immunodeficiency virus (HIV) infection. Human autologous CD34-positive HPCs are isolated and transduced ex vivo with the lentiviral vector. Upon pre-selection, purification using CD25 immunomagnetic separation, and subsequent administration of effectively transduced HPCs, the HPCs display 3 separate mechanisms of action against HIV infection: CCR5 shRNA binds to CCR5 mRNA and inhibits the expression of CCR5, a HIV-1 co-receptor that mediates HIV attachment and host cell entry; TRIM5alpha prevents HIV genome integration upon cell entry; and the TAR decoy binds to the HIV TAT protein and prevents TAT-dependent viral gene transcription, thereby preventing HIV replication. Upon transfer of the lentivirus vector CCR5 shRNA/TRIM5alpha/TAR decoy-transduced autologous CD34-positive HPCs into the patient, the HPCs are resistant to HIV entry and replication and could provide long-term protection against both HIV infection and HIV-associated cancers.
- lentivirus vector rHIV7-shI-TAR-CCR5RZ-transduced hematopoietic progenitor cells
- Autologous, CD34-positive hematopoietic progenitor cells (HPCs) transduced with rHIV7-shI-TAR-CCR5RZ, a lentiviral vector encoding three anti-human immunodeficiency virus (HIV) RNA genes, with potential antineoplastic activity. The 3 RNA products produced by the lentilvirus are: a short hairpin RNA (shRNA) targeted to an exon of the HIV-1 genes tat/rev, designated as shI; a decoy for the HIV TAT reactive element, designated as TAR; a ribozyme targeting the host cells CCR5 chemokine receptor, designated as CCR5RZ. Upon administration, lentivirus vector rHIV7-shI-TAR-CCR5RZ-transduced hematopoietic progenitor cells expressing the 3 species of RNAs display 3 seperate mechanims of action: the shRNA blocks the transcription of tat/rev, the TAR decoy binds to the TAT protein that is essential for HIV replication, and CCR5RZ catalyzes CCR5 which is needed for viral attachment and entry into the host cells. Altogether, infusion of these HPCs may ultimately inhibit HIV replication and suppress HIV infection.
- lenumlostat
- An orally available, small-molecule, irreversible inhibitor of lysyl oxidase homolog 2 (lysyl oxidase-like protein 2; LOXL2) with potential antifibrotic activity. Upon oral administration, the aminomethyl pyridine moiety of lenumlostat interacts with the active site of LOXL2 to form a pseudo-irreversible inhibitory complex, thereby inhibiting the catalytic activity of LOXL2. LOXL2, a secreted glycoprotein, catalyzes the post-translational oxidative deamination of lysine residues on target proteins, including collagen and elastin, leading to the formation of deaminated lysine (allysine). Condensation with other allysines or lysines drives the formation of inter- and intramolecular cross-linkages that impact remodeling of the extracellular matrix (ECM), potentially leading to fibrosis. Inhibition of LOXL2, which is often upregulated in fibrotic tissue, may reduce fibrosis in certain chronic fibrotic diseases.
- lenvatinib mesylate
- A synthetic, orally available inhibitor of vascular endothelial growth factor receptor 2 (VEGFR2, also known as KDR/FLK-1) tyrosine kinase with potential antineoplastic activity. Lenvatinib mesylate blocks VEGFR2 activation by VEGF, resulting in inhibition of the VEGF receptor signal transduction pathway, decreased vascular endothelial cell migration and proliferation, and vascular endothelial cell apoptosis.
- Lenvima
- (Other name for: lenvatinib mesylate)
- lenzilumab
- A recombinant monoclonal antibody against the cytokine granulocyte macrophage colony-stimulating factor (GM-CSF), with potential immunomodulating activity. Upon administration, lenzilumab binds to and neutralizes GM-CSF. This prevents GM-CSF binding to the GM-CSF receptor, which is a heterodimeric protein expressed on myeloid progenitor cells, and prevents GM-CSF-mediated signaling. This may induce apoptosis in and inhibit proliferation of cancer cells that overproduce GM-CSF. GM-CSF plays a key role in the differentiation and proliferation of monocytes, macrophages and granulocytes; elevated levels of GM-CSF are associated with certain autoimmune diseases, inflammatory diseases, and cancers.
- LEP-ETU
- (Other name for: paclitaxel liposome)
- lepirudin
- A yeast cell-derived recombinant polypeptide related to the naturally occurring, leech-derived anticoagulant hirudin. Lepirudin directly binds to and inactivates thrombin, producing dose-dependent increases in the activated partial thromboplastin time (aPTT) and prothrombin time (PT). The mechanism of action of this agent is independent of antithrombin III and is not inhibited by platelet factor 4. Natural hirudin, a family of highly homologous isopolypeptides, is produced in trace amounts by the leech Hirudo medicinalis.
- lerapolturev
- A recombinant, live attenuated, nonpathogenic oncolytic virus containing the oral poliovirus Sabin type 1 in which the internal ribosomal entry site (IRES) is replaced with the IRES from human rhinovirus type 2 (HRV2), with potential antineoplastic activity. Upon administration of lerapolturev, the poliovirus is selectively taken up by and replicates in tumor cells expressing CD155 (poliovirus receptor, PVR or NECL5) eventually causing tumor cell lysis. Following the lysis of infected cells, the replicated virus is released and can infect adjacent cells, which both induces further tumor cell oncolysis and may activate, through the release of tumor-associated antigens (TAAs) and inflammatory mediators from the lysed tumor cells, the immune system to mount an anti-tumor immune response. This further kills tumor cells. This may also stimulate long-term anti-tumor immunity. Additionally, lerapolturev can induce a systemic anti-tumor immune response through engagement with antigen-presenting cells (APCs) upon CD155 binding thereby further killing tumor cells. CD155, an oncofetal cell adhesion molecule and tumor antigen, is ectopically expressed in certain cancers, such as glioblastoma multiforme (GMB), and plays an important role in tumor cell migration, invasion, and metastasis. Due to the heterologous HRV2 IRES in this recombinant virus, lerapolturev only propagates in susceptible CD155-expressing, nonneuronal neoplastic cells.
- leridistim
- A recombinant chimeric dual G-CSF and IL-3 receptor agonist. Leridistim binds with high affinity to both the interleukin-3 (IL-3) and granulocyte colony-stimulating factor (G-CSF) receptors, thereby stimulating the production and maturation of neutrophils, platelets, and lymphocytes after chemotherapy.
- leriglitazone
- An orally bioavailable, blood-brain-barrier (BBB) penetrable, selective peroxisome proliferator-activated receptor (PPAR) subtype gamma agonist, with potential neuroprotective activity that could be used for certain central nervous system (CNS) diseases, such as adrenomyeloneuropathy, cerebral adrenoleukodystrophy (cALD), Friedreich's ataxia, and certain other CNS diseases. Upon oral administration, leriglitazone selectively targets, binds to and activates PPARgamma, thereby regulating the expression of genes involved in mitochondrial biogenesis. This modulates pathways leading to the restoration of mitochondrial function in which dysfunction is caused by the accumulation of very long-chain fatty acids (VLCFAs), and increases energy production, decreases oxidative stress, decreases nuclear factor kappa B (NF-kB) levels, inhibits neuroinflammation, protects the BBB integrity, prevents demyelination and axonal degeneration, increases neuronal survival, increases myelination and oligodendrocyte survival and improves motor function. Mutations in the ABCD1 gene, which encodes the peroxisomal membrane adrenoleukodystrophy protein, cause a defective function of the ABCD1 transporter leading to an accumulation of VLCFA. VLCFA accumulation contributes to membrane destabilization of the myelin sheath, mitochondrial dysfunction, oxidative stress, neuroinflammation and compromised BBB integrity.
- lerisetron
- The hydrochloride salt of a 2-piperazinylbenzimidazole-derivative serotonin type 3 (5-HT3) receptor antagonist with antiemetic activity. Lerisetron specifically binds to 5-HT3 receptors, located peripherally on vagus nerve terminals and centrally in the chemoreceptor trigger zone (CTZ) of the area postrema, which may result in suppression of chemotherapy-induced nausea and vomiting.
- lerociclib
- An orally bioavailable inhibitor of cyclin-dependent kinase (CDK) types 4 (CDK4) and 6 (CDK6), with potential antineoplastic activity. Upon administration, lerociclib selectively inhibits CDK4 and CDK6, which inhibits the phosphorylation of retinoblastoma protein (Rb) early in the G1 phase, prevents CDK-mediated G1-S phase transition and leads to cell cycle arrest. This suppresses DNA replication and decreases tumor cell proliferation. CDK4 and 6 are serine/threonine kinases that are upregulated in many tumor cell types and play a key role in the regulation of both cell cycle progression from the G1-phase into the S-phase and tumor cell proliferation.
- leronlimab
- A humanized immunoglobulin (Ig) G4 monoclonal antibody against CC chemokine receptor 5 (CCR5; CD195), with potential activity as a human immunodeficiency virus (HIV) entry blocker and potential protective activity against graft-versus-host disease (GvHD). Upon administration, leronlimab targets and binds to CCR5 expressed on T cells. This blocks HIV cell entry, which prevents HIV infection and/or reduces HIV viral load. In addition, blocking CCR5 by PRO 140 decreases CCR5-mediated signaling and the CCR5-induced migration of donor cells into tissues after an allogeneic hematopoietic cell transplantation (HCT). Blocking CCR5 may therefore prevent or reduce GvHD. CCR5, a co-receptor needed for HIV cell entry, plays a key role in immunomodulation. Expressed on monocytes, activated T cells and dendritic cells (DCs), CCR5 can regulate chemotaxis. Lymphocyte trafficking via chemokine receptors, such as CCR5, and recruitment to target organs, plays a critical role in alloreactive responses.
- Lescol
- (Other name for: fluvastatin sodium)
- Lessina
- (Other name for: ethinyl estradiol/levonorgestrel)
- lestaurtinib
- An orally bioavailable indolocarbazole derivative with antineoplastic properties. Lestaurtinib inhibits autophosphorylation of FMS-like tyrosine kinase 3 (FLT3), resulting in inhibition of FLT3 activity and induction of apoptosis in tumor cells that overexpress FLT3.
- letermovir
- An orally bioavailable, non-nucleoside, 3,4-dihydroquinazolinyl acetic acid and inhibitor of the pUL56 subunit of the viral terminase complex of cytomegalovirus (CMV), with potential CMV-specific antiviral activity. Upon oral administration, letermovir binds to the pUL56 subunit of the viral terminase complex of CMV and prevents the cleavage of concatemeric DNA into monomeric genome length DNA. As this agent interferes with viral DNA processing and subsequent viral DNA packaging into procapsids, CMV replication is blocked and CMV infection is prevented.
- letetresgene autoleucel
- Human autologous T lymphocytes transduced with a lentiviral vector encoding a T-cell receptor (TCR) specific for the cancer-testis antigens (CTAs) NY-ESO-1 and L antigen family member 1 (LAGE-1; Cancer/Testis Antigen 2; CTAG2; CT2), with potential antineoplastic activity. Following leukapheresis, isolation of lymphocytes, expansion ex vivo, transduction, and reintroduction into the patient, letetresgene autoleucel specifically target and bind to NY-ESO-1/LAGE-1-overexpressing tumor cells. This may result in a cytotoxic T-lymphocyte (CTL)-mediated elimination of NY-ESO-1/LAGE-1-positive cancer cells. NY-ESO-1 and LAGE-1, members of the cancer-testis antigen (CTA) family, are overexpressed on the surface of various tumor cell types.
- letrozole
- A nonsteroidal inhibitor of estrogen synthesis with antineoplastic activity. As a third-generation aromatase inhibitor, letrozole selectively and reversibly inhibits aromatase, which may result in growth inhibition of estrogen-dependent breast cancer cells. Aromatase, a cytochrome P-450 enzyme localized to the endoplasmic reticulum of the cell and found in many tissues including those of the premenopausal ovary, liver, and breast, catalyzes the aromatization of androstenedione and testosterone into estrone and estradiol, the final step in estrogen biosynthesis.
- letrozole/palbociclib regimen
- A regimen consisting of letrozole and palbociclib that can be used in the treatment of breast cancer.
- leucine-enhanced essential amino acid dietary supplement
- An orally bioavailable leucine enriched essential amino acid dietary supplement with potential anti-cachexia activity. Leucine-enhanced essential amino acid nutritional supplement may stimulate the mammalian target of rapamycin (mTOR) signaling pathway, which may promote protein synthesis in muscle cells. Although the exact mechanism by which leucine and other essential amino acids stimulate mTOR has yet to be fully elucidated, leucine may stimulate mTOR by inhibiting adenosine monophosphate protein kinase (AMPK), which negatively controls mTOR signaling.
- leucovorin calcium
- An active metabolite of folic acid (also called folinic acid and citrovorum factor), which does not require metabolism by dihydrofolate reductase, the molecular target of folate antagonist-type chemotherapeutic drugs. Leucovorin calcium counteracts the toxic effects of these medications, 'rescuing' the patient while permitting the antitumor activity of the folate antagonist. This agent also potentiates the effects of fluorouracil and its derivatives by stabilizing the binding of the drug's metabolite to its target enzyme, thus prolonging drug activity.
- leukemic apoptotic corpse-pulsed autologous dendritic cells
- A cell-based cancer vaccine composed of autologous dendritic cells (DCs) pulsed with corpses of apoptotic leukemic cells, with potential immunostimulatory and antineoplastic activities. Upon vaccination, autologous dendritic cells pulsed with leukemic apoptotic corpse may activate the immune system to mount an anti-tumoral cytotoxic T-lymphocyte (CTL) response against leukemic cells expressing leukemia-associated antigens, which may result in leukemic cell lysis and inhibition of tumor cell growth. Apoptotic tumor cell corpses contain an array of tumor associated antigens (TAAs).
- Leukeran
- (Other name for: chlorambucil)
- Leukine
- (Other name for: sargramostim)
- leuprolide acetate
- The acetate salt of a synthetic nonapeptide analogue of gonadotropin-releasing hormone. Leuprolide binds to and activates gonadotropin-releasing hormone (GnRH) receptors. Continuous, prolonged administration of leuprolide in males results in pituitary GnRH receptor desensitization and inhibition of pituitary secretion of follicle stimulating hormone (FSH) and luteinizing hormone (LH), leading to a significant decline in testosterone production; in females, prolonged administration results in a decrease in estradiol production. This agent reduces testosterone production to castration levels and may inhibit androgen receptor-positive tumor progression.
- leuprolide acetate for injectable suspension TOL2506
- A subcutaneous injectable suspension formulation containing the acetate salt form of leuprolide, a synthetic nonapeptide analogue of gonadotropin-releasing hormone (GnRH), with potential antineoplastic activity. Upon subcutaneous administration of the leuprolide acetate for injectable suspension TOL2506, leuprolide binds to and activates the gonadotropin-releasing hormone receptor (GnRHR). The continuous stimulation of GnRHR by leuprolide results in both the desensitization of pituitary GnRHR and the inhibition of pituitary secretion of the gonadotropins follicle stimulating hormone (FSH) and luteinizing hormone (LH). In males, this results in a significant decline in testosterone production to castration levels and may inhibit androgen receptor-positive tumor progression. In females, this decreases estradiol production and level, suppresses ovarian function and may inhibit proliferation of estrogen receptor (ER)-positive breast cancer.
- leuprolide acetate sustained-release microspheres PT105
- A sustained-release (SR) injectable microsphere formulation composed of the acetate salt of leuprolide, a synthetic, long-acting nonapeptide analog of the endogenous hormone gonadotropin-releasing hormone (GnRH), with potential antineoplastic activity. Upon administration, leuprolide binds to and activates the gonadotropin-releasing hormone receptor (GnRHR). The continuous stimulation of GnRHR by leuprolide results in both the desensitization of pituitary GnRHR and the inhibition of pituitary secretion of the gonadotropins follicle stimulating hormone (FSH) and luteinizing hormone (LH). In females, prolonged administration results in a decrease in estradiol production and suppression of ovarian function. Leuprolide also reduces testosterone production to castration levels and may inhibit androgen receptor-positive tumor progression.
- leuprolide mesylate
- The mesylate salt form of leuprolide, a synthetic nonapeptide analogue of gonadotropin-releasing hormone (GnRH), with potential antineoplastic activity. Upon administration, leuprolide binds to and activates the gonadotropin-releasing hormone receptor (GnRHR). The continuous stimulation of GnRHR by leuprolide results in both the desensitization of pituitary GnRHR and the inhibition of pituitary secretion of the gonadotropins follicle stimulating hormone (FSH) and luteinizing hormone (LH). In males, this results in a significant decline in testosterone production to castration levels and may inhibit androgen receptor-positive tumor progression.
- Leuvectin
- (Other name for: IL-2 plasmid DNA/lipid complex)
- levamisole hydrochloride
- The orally bioavailable hydrochloride salt of the synthetic imidazothiazole derivative levamisole with anthelminthic and immunostimulating activities. In immunosuppressed states, levamisole may restore immune function by: 1) stimulating antibody formation, 2) stimulating T-cell activation and proliferation, 3) potentiatiating monocyte and macrophage phagocytosis and chemotaxis and 4) increasing neutrophil mobility, adherence, and chemotaxis.
- Levaquin
- (Other name for: levofloxacin)
- levetiracetam
- A pyrrolidine with antiepileptic activity. The exact mechanism through which levetiracetam exerts its effects is unknown but does not involve inhibitory and excitatory neurotransmitter activity. Stereoselective binding of levetiracetam was confined to synaptic plasma membranes in the central nervous system with no binding occurring in peripheral tissue. Levetiracetam inhibits burst firing without affecting normal neuronal excitability, which suggests that it may selectively prevent hyper-synchronization of epileptiform burst firing and propagation of seizure activity.
- Levitra
- (Other name for: vardenafil hydrochloride)
- Levlite
- (Other name for: ethinyl estradiol/levonorgestrel)
- levobupivacaine hydrochloride
- The hydrochloride salt of levobupivacaine, an amide derivative with anesthetic property. Levobupivacaine reversibly binds voltage-gated sodium channels to modulate ionic flux and prevent the initiation and transmission of nerve impulses (stabilizing neuronal membrane), thereby resulting in analgesia and anesthesia. In comparison with racemic bupivacaine, levobupivacaine is associated with less vasodilation and has a longer duration of action.
- levocarnitine
- An amino acid derivative. Levocarnitine facilitates long-chain fatty acid entry into mitochondria, delivering substrate for oxidation and subsequent energy production. Fatty acids are utilized as an energy substrate in all tissues except the brain.
- levocetirizine dihydrochloride
- The dihydrochloride salt form of the active levorotatory enantiomer of cetirizine, levocetirizine; a third generation, non-sedating, selective histamine H1 receptor antagonist, with antihistamine, anti-inflammatory and potential anti-angiogenic activities. Levocetirizine competes with endogenous histamine for binding at peripheral H1-receptor sites on the effector cell surface. This prevents the negative symptoms associated with histamine release and an allergic reaction. In addition, as histamine plays an important role in angiogenesis during an allergic inflammatory reaction, blocking the action of histamine may modulate the expression of proangiogenic factors and thus may prevent angiogenesis. As a third-generation histamine H1 receptor antagonist, levocetirizine has fewer side effects than most second-generation antihistamines.
- levodopa
- An amino acid precursor of dopamine with antiparkinsonian properties. Levodopa is a prodrug that is converted to dopamine by DOPA decarboxylase and can cross the blood-brain barrier. When in the brain, levodopa is decarboxylated to dopamine and stimulates the dopaminergic receptors, thereby compensating for the depleted supply of endogenous dopamine seen in Parkinson's disease. To assure that adequate concentrations of levodopa reach the central nervous system, it is administered with carbidopa, a decarboxylase inhibitor that does not cross the blood-brain barrier, thereby diminishing the decarboxylation and inactivation of levodopa in peripheral tissues and increasing the delivery of dopamine to the CNS.
- levofloxacin
- A broad-spectrum, third-generation fluoroquinolone antibiotic and optically active L-isomer of ofloxacin with antibacterial activity. Levofloxacin diffuses through the bacterial cell wall and acts by inhibiting DNA gyrase (bacterial topoisomerase II), an enzyme required for DNA replication, RNA transcription, and repair of bacterial DNA. Inhibition of DNA gyrase activity leads to blockage of bacterial cell growth.
- levoketoconazole
- An orally available levorotary enantiomer of ketoconazole with potential steroidogenesis inhibitory activity. Following oral administration, levoketoconazole inhibits three cytochrome P450 family enzymes involved in glucocorticoid biosynthesis, 11beta-hydroxylase (CYP11B1), 17alpha-hydroxylase/17,20-lyase (CYP17A1) and steroid 21-hydroxylase (CYP21A2), which reduces the circulating levels of glucocorticoids. Therefore, this agent may normalize the high concentration of cortisol in the blood seen in patients with Cushing syndrome. Compared to racemic ketoconazole, the levo form is a more potent inhibitor of glucocorticoid synthesis. Additionally, this enantiomer is less likely to inhibit cholesterol 7alpha-hydroxylase (CYP7A1); therefore, its use may reduce the risk of hepatoxicity. Cushing syndrome is caused by high levels of cortisol in the blood either due to excessive production and secretion of corticosteroids, which is often the result of adrenocorticotropic hormone (ACTH)-secreting pituitary or adrenocortical neoplasms, or the use of synthetic corticosteroids.
- levoleucovorin calcium
- A levo isoform of leucovorin calcium with antineoplastic activity. Levoleucovorin is an active metabolite of folic acid, which does not require metabolism by dihydrofolate reductase. This agent counteracts the toxic effects of other folic acid derivative agents, rescuing the patient while permitting the antitumor activity of the folate antagonist. This agent also potentiates the effects of fluorouracil and its derivatives by stabilizing the binding of the drug's metabolite to its target enzyme, thus prolonging drug activity.
- levonantradol
- A synthetic cannabinoid analogue of delta (9)-tetrahydrocannabinol (delta(9)-THC) with antiemetic and anti-analgesic properties. Although its precise mechanism of action is unknown, levonantradol appears to bind and activate the cannabinoid receptors CB1 and/or CB2.
- levonorgestrel
- The levorotatory form of norgestrel and synthetic progestogen with progestational and androgenic activity. Levonorgestrel binds to the progesterone receptor in the nucleus of target cells, thereby stimulating the resulting hormone-receptor complex, initiating transcription, and increasing the synthesis of certain proteins. This results in a suppression of luteinizing hormone (LH) activity and an inhibition of ovulation, as well as an alteration in the cervical mucus and endometrium.
- levonorgestrel-releasing intrauterine system
- A long-acting, hormone-releasing, intrauterine device consisting of a small, T-shaped, polyethylene frame and a reservoired synthetic progesterone with progestational and potential antineoplastic activities. After insertion of this system into the uterus, the device slowly and gradually releases the hormone. Levonorgestrel acts by binding to the progesterone receptor in the nuclei of target cells, resulting in transcription activation and an alteration in protein synthesis. Subsequently, luteinizing hormone (LH) activity and ovulation are suppressed. Levonorgestrel may also exhibit antiproliferative activity in endometrial tissue.
- Levopa
- (Other name for: levodopa)
- Levora
- (Other name for: ethinyl estradiol/levonorgestrel)
- Levothroid
- (Other name for: levothyroxine sodium)
- levothyroxine sodium
- The sodium salt of levothyroxine, a synthetic levoisomer of thyroxine (T4) that is similar to the endogenous hormone produced by the thyroid gland. In peripheral tissues, levothyroxine is deiodinated by 5'-deiodinase to form triiodothyronine (T3). T3 enters the cell and binds to nuclear thyroid hormone receptors; the activated hormone-receptor complex in turn triggers gene expression and produces proteins required in the regulation of cellular respiration; thermogenesis; cellular growth and differentiation; and the metabolism of proteins, carbohydrates and lipids. T3 also exhibits cardiostimulatory effects.
- Levulan Kerastick
- (Other name for: aminolevulinic acid hydrochloride)
- Lexapro
- (Other name for: escitalopram oxalate)
- lexaptepid pegol
- A proprietary 44-nucleotide L-stereoisomer RNA oligonucleotide conjugated to a 40 kDa polyethylene glycol (PEG) that targets hepcidin with potential anti-anemic activity. Upon intravenous or subcutaneous administration, lexaptepid pegol binds to hepcidin and prevents it from binding to the iron channel ferroportin, located on the basolateral surface of gastrointestinal enterocytes and the plasma membrane of macrophages. This prevents hepcidin-induced internalization and degradation of ferroportin, thus decreasing macrophage iron retention. In turn, binding of NOX-H94 to hepcidin normalizes plasma iron levels and increases erythropoiesis. This may inhibit anemia caused by inflammation. Hepcidin, a peptide hormone that plays a key role in the homeostasis of systemic iron, is upregulated during acute and chronic inflammation in response to cytokines. The unique mirror-image configuration of this agent renders it resistant to hydrolysis and shows a low antigenicity profile. Pegylation increases the half-life of this agent.
- lexatumumab
- A fully human monoclonal agonistic antibody directed against tumor necrosis factor-alpha (TNF-alpha)-related apoptosis-inducing ligand receptor-2 (TRAIL-R2) with potential antitumor activity. Mimicking the natural ligand TRAIL, lexatumumab binds to and activates TRAIL-R2, which may trigger apoptosis in and inhibit the growth of TRAIL-R2-expressing tumor cells. TRAIL-R2, also known as death receptor 5 (DR5), is a member of the TNF receptor family and is expressed on many malignant cell types.
- lexibulin
- An orally bioavailable small-molecule with tubulin-inhibiting, vascular-disrupting, and potential antineoplastic activities. Lexibulin inhibits tubulin polymerization in tumor blood vessel endothelial cells and tumor cells, blocking the formation of the mitotic spindle and leading to cell cycle arrest at the G2/M phase; this may result in disruption of the tumor vasculature and tumor blood flow, and tumor cell death.
- Lexiscan
- (Other name for: regadenoson)
- Lialda
- (Other name for: mesalamine)
- liarozole fumarate
- The orally active fumarate salt of the benzimidazole derivative liarozole with potential antineoplastic activity. As a retinoic acid metabolism blocking agent (RAMBA), liarozole inhibits cytochrome P450-dependent all-trans-retinoic acid (ATRA)-4-hydroxylase, resulting in an increase in endogenous ATRA production, inhibition of cell proliferation, and induction of cell differentiation. This agent also inhibits aromatase, the enzyme that catalyzes the final, rate-limiting step in estrogen biosynthesis.
- Libtayo
- (Other name for: cemiplimab-rwlc)
- licartin
- An immunoradioconjugate containing metuximab, an antibody fragment targeting the hepatocellular cancer (HCC)-associated antigen HAb18G/CD147, that is conjugated to the radioisotope iodine I 131, with potential antineoplastic activity. Upon administration, the metuximab moiety of licartin targets and binds to HAb18G/CD147 on HCC cells; upon internalization, the radioisotope I 131 delivers a cytotoxic dose of gamma radiation, thereby causing selective destruction of HAb18G/CD147-expressing cells. HAb18G/CD147, a member of CD147 family, is overexpressed in HCC and fibroblasts and its expression is associated with cancer cell progression and increased adhesion, invasion and metastasis.
- licochalcone A
- A derivative of the phenol chalconoid, found in and extracted from the roots of Glycyrrhiza species G. glabra and inflata, with potential anti-inflammatory, antibacterial, and anticancer activities. Upon administration, licochalcone A inhibits the phosphatidylinositol-3-kinase/Akt/mammalian target of rapamycin (PI3K/Akt/mTOR) signaling pathway and inhibits the activity of c-Jun N-terminal kinase 1 (JNK-1), a member of the mitogen-activated protein kinase (MAPK) family that plays a role in the MAPK-mediated signaling pathway. Inhibition of the PI3K/Akt/mTOR- and MAPK-signaling pathways induces cell cycle arrest and apoptosis, decreases migration and invasion of cancer cells, and inhibits tumor cell proliferation. Licochalcone A also prevents the production of reactive oxygen species (ROS), and reduces oxidative stress through the nuclear factor-erythroid 2-related factor 2 (Nrf2) pathway.
- licogliflozin
- An inhibitor of the sodium-dependent glucose co-transporter (sodium-glucose transporter; sodium-glucose transport protein; sodium-glucose linked transporter; SGLT) family members 1 and 2 (SGLT1/2) with antihyperglycemic activity. By binding to and blocking SGLT1/2, licogliflozin suppresses the reabsorption of glucose in the proximal tubule within the kidneys and enhances urinary excretion of glucose. This normalizes blood glucose levels. SGLT1/2, parts of a transport system expressed in the proximal renal tubules, mediate the majority of renal glucose reabsorption from tubular fluid.
- licorice
- An herbal extract derived from the root of the plant Glycyrrhiza glabra with potential anti-inflammatory, antioxidant, and antineoplastic activities. Licorice root extract contains glycoside glycyrrhizinic acid and numerous flavonoids. Glycyrrhizinic acid in licorice root extract is hydrolyzed to glycyrrhetic acid (GA); GA inhibits 11 beta-hydroxysteroid dehydrogenase, resulting in inhibition of the conversion of cortisol to the inactive steroid cortisone and elevated cortisol levels. In addition, GA inhibits 17,20-lyase and 17 beta-hydroxysteroid dehydrogenase, resulting in decreased conversions of 17-hydroxyprogesterone to androstenedione and androstenedione to testosterone. The primary antioxidant found in licorice root, the flavonoid glabridin, may inactivate or inhibit the activities of some cytochrome P450 enzymes. In tumor cells, beta-hydroxy-DHP, another flavonoid, may induce Bcl-2 phosphorylation, apoptosis, and G2/M cell cycle arrest.
- Lidex
- (Other name for: fluocinonide cream)
- lidocaine hydrochloride
- The hydrochloride salt form of lidocaine, an aminoethylamide and a prototypical member of the amide class anesthetics. Lidocaine interacts with voltage-gated Na+ channels in the nerve cell membrane and blocks the transient increase in permeability of excitable membranes to Na+. This prevents the generation and conduction of nerve impulses and produces a reversible loss of sensation. Lidocaine hydrochloride also exhibits class IB antiarrhythmic effects. The agent decreases the flow of sodium ions into myocardial tissue, especially on the Purkinje network, during phase 0 of the action potential, thereby decreasing depolarization, automaticity and excitability.
- lidocaine hydrochloride ophthalmic gel
- An ophthalmic gel formulation containing the synthetic amide-type anesthetic lidocaine, with potential analgesic activity. Upon ophthalmic application, the active ingredient lidocaine binds to and blocks voltage-gated sodium channels in neuronal cell membranes. Lidocaine-mediated stabilization of neuronal membranes inhibits the initiation and conduction of nerve impulses, which numbs the nerves, prevents the trigemino-cardiac reflex and produces a reversible local anesthesia.
- lidocaine mixture with tribenoside
- A formulation composed of the local anesthetic lidocaine and the vasoprotective agent tribenoside that can be used for the treatment of hemorrhoids. Upon rectal administration of the lidocaine mixture with tribenoside, lidocaine stabilizes the neuronal membrane by binding to and inhibiting voltage-gated sodium channels, thereby inhibiting the ionic fluxes required for the initiation and conduction of impulses. This causes local anesthesia and relieves pain. Tribenoside may exert anti-inflammatory, mild analgesic, wound-healing, fibrinolysis-promoting, membrane-stabilizing and venotropic properties. This may relieve pain, halt inflammation, protect blood vessels, and may help repair and heal wounds.
- lidocaine patch 5%
- A transdermal patch containing a 5 percent aqueous base solution of the synthetic amide-type anesthetic lidocaine with analgesic activity. Upon topical application and transdermal delivery, the active ingredient lidocaine binds to and blocks voltage-gated sodium channels in the neuronal cell membrane; lidocaine-mediated stabilization of neuronal membranes inhibits the initiation and conduction of nerve impulses and produces a reversible local anesthesia.
- lidocaine topical
- A synthetic aminoethylamide with local anesthetic activity applied topically to either the skin or mucous membranes. Lidocaine stabilizes the neuronal cell membrane by binding to and inhibiting voltage-gated sodium channels, thereby inhibiting the initiation and conduction of nerve impulses and producing a reversible loss of sensation.

- Life-Mel
- (Other name for: honey-based nutritional supplement)
- Life-Mel Honey
- (Other name for: honey-based nutritional supplement)
- lifileucel
- A preparation of autologous tumor infiltrating lymphocytes (TILs), with potential antineoplastic activity. TILs are isolated from a patient's tumor tissue, cultured in vitro with high-dose interleukin-2 (lL-2), further selected based on antigen specificity and tumor reactivity, and the selected TILs are subsequently expanded. Upon re-introduction of lifileucel into the patient, the TILs re-infiltrate the tumor, specifically recognize the tumor-associated antigens (TAAs), and initiate tumor cell lysis. IL-2 induces the proliferation and expansion of TILs in vitro.
- ligand directed degrader BMS-986460
- A ligand directed degrader (LDD) composed of an E3 ubiquitin ligase-binding moiety that is conjugated, via a linker, to an as of yet undisclosed moiety that targets a prostate specific tumor-associated antigen (TAA), with potential antineoplastic activity. Upon administration, LDD BMS-986460 specifically and simultaneously targets and binds to the TAA on prostate tumor cells and to E3 ubiquitin ligase, thereby creating a ternary complex. This induces E3 ligase ubiquitination and proteasome-mediated degradation of the TAA. This prevents TAA-mediated signaling and leads to an inhibition of the growth of tumor cells that overexpress the unidentified TAA.
- lignin-derived polyphenolic composition with ammonium molybdate BP-C2
- An orally bioavailable solution containing lignin-derived benzene-polycarboxylic acids mixed with ammonium molybdate, with potential use as an adjuvant and with potential radioprotective and regenerative activities. Upon oral administration, lignin-derived polyphenolic composition with ammonium molybdate BP-C2 is also able to stimulate the innate immune system and upregulates a variety of cytokines including interferon (IFN), tumor necrosis factor-alpha (TNF-alpha), granulocyte macrophage-colony stimulating factor (GM-CSF), and various interleukins (ILs) such as IL-6, IL-22 and IL-25, and induces the production of innate lymphoid cells. BP-C2 stimulates the production of intestinal epithelial cells thereby protecting the gastrointestinal (GI) tract against GI-induced cytotoxic side effects caused by certain anti-tumor agents. Additionally, BP-C2 scavenges free radicals, inhibits lipid oxidation, and protects cells against radiation-induced damage. Molybdenum, an essential micronutrient, acts as a cofactor in multiple detoxification system enzymes. BP-C2 may also stimulate the production of hematopoietic progenitor cells, thereby correcting hematological abnormalities such as anemia, thrombocytopenia and neutropenia, which are also caused by certain anti-cancer agents.
- ligufalimab
- A humanized immunoglobulin G4 (IgG4) monoclonal antibody targeting leukocyte surface antigen CD47, with potential immune checkpoint inhibitory and antineoplastic activities. Upon administration, ligufalimab targets and binds to CD47 expressed on tumor cells, blocking the interaction of CD47 with signal regulatory protein alpha (SIRPa) expressed on phagocytic cells. This prevents CD47/SIRPa-mediated signaling and abrogates the CD47/SIRPa-mediated inhibition of macrophage activation and phagocytosis of cancer cells. This induces pro-phagocytic signaling mediated by the binding of calreticulin (CRT), which is specifically expressed on the surface of tumor cells, to low-density lipoprotein (LDL) receptor-related protein-1 (LRP-1), which is expressed on macrophages, and results in macrophage activation and the specific phagocytosis of tumor cells. CD47, also called integrin-associated protein (IAP), is a tumor-associated antigen (TAA) expressed on normal, healthy hematopoietic stem cells (HSCs) and overexpressed on the surface of a variety of cancer cells. Expression of CD47, and its interaction with SIRPa, leads to the inhibition of macrophage activation and protects cancer cells from phagocytosis, thereby allowing cancer cells to proliferate.
- lilotomab
- A murine immunoglobulin G1 (IgG1) monoclonal antibody directed against the CD37 antigen with potential antineoplastic activity. Upon administration, lilotomab both activates the immune system to induce an antibody-dependent cell-mediated cytotoxicity (ADCC) against CD37-overexpressing tumor cells and induces apoptosis in these tumor cells. CD37 is a transmembrane glycoprotein expressed at high-levels on B-cells and to a lesser extent on T cells and myeloid cells, and is frequently overexpressed in certain B-cell malignancies.
- limonene, (+)-
- An oral dietary supplement containing a natural cyclic monoterpene, and a major component of the oil extracted from citrus peels, with potential chemopreventive and antineoplastic activities. Upon oral administration, D-limonene activates aldehyde dehydrogenase 3A1 (ALDH3A1), thereby decreasing aldehyde level. This may protect salivary stem/progenitor cells (SSPCs) from toxic aldehydes and prevent or improve radiation-induced xerostomia. Limonene and its metabolites perillic acid, dihydroperillic acid, uroterpenol and limonene 1,2-diol may also inhibit tumor growth through inhibition of p21-dependent signaling and may induce apoptosis via the induction of the transforming growth factor beta-signaling pathway. In addition, they inhibit post-translational modification of signal transduction proteins, resulting in G1 cell cycle arrest as well as differential expression of cell cycle- and apoptosis-related genes.
- linaclotide acetate
- The acetate salt form of linaclotide, a synthetic, fourteen amino acid peptide and agonist of intestinal guanylate cyclase type C (GC-C), which is structurally related to the guanylin peptide family, with secretagogue, analgesic and laxative activities. Upon oral administration, linaclotide binds to and activates GC-C receptors located on the luminal surface of the intestinal epithelium. This increases the concentration of intracellular cyclic guanosine monophosphate (cGMP), which is derived from guanosine triphosphate (GTP). cGMP activates the cystic fibrosis transmembrane conductance regulator (CFTR) and stimulates the secretion of chloride and bicarbonate into the intestinal lumen. This promotes sodium excretion into the lumen and results in increased intestinal fluid secretion. This ultimately accelerates GI transit of intestinal contents, improves bowel movement and relieves constipation. Increased extracellular cGMP levels may also exert an antinociceptive effect, through an as of yet not fully elucidated mechanism, that may involve modulation of nociceptors found on colonic afferent pain fibers. Linaclotide is minimally absorbed from the GI tract.
- linagliptin
- A potent, orally bioavailable dihydropurinedione-based inhibitor of dipeptidyl peptidase 4 (DPP-4), with hypoglycemic activity. The inhibition of DPP-4 by linagliptin appears to be longer lasting than that by some other DPP-4 inhibitors tested.
- Lindera obtusiloba extract
- A dietary supplement composed of an ethanol extracted powder of Lindera obtusiloba, with potential antioxidant and anti-inflammatory activities. Upon administration, Lindera obtusiloba extract (LOE) may promote anti-oxidant activities through the activation of nuclear factor erythroid 2-related factor 2 (Nrf-2)/heme oxygenase 1 (HO-1)/ NAD(P)H dehydrogenase [quinone] 1 (NQO1), which reduces the production of reactive oxygen species (ROS) and lowers ROS-mediated oxidative stress. In addition, LOE may exert anti-inflammatory effects through the inhibition of the phosphorylation and activation of mitogen-activated protein kinases (MAPKs) and nuclear factor-kappa B (NF-kB).
- linezolid
- A synthetic oxazolidinone derivative, linezolid selectively inhibits an early step in bacterial protein synthesis and affects blood pressure through monoamine oxidase inhibition. It is effective against Gram-positive organisms, including methicillin-resistant Staphylococcus aureus strains, coagulase-negative Staphylococci, vancomycin-resistant Enterococci, and penicillin-resistant Streptococcus pneumoniae strains.
- linifanib
- An orally bioavailable, small-molecule receptor tyrosine kinase (RTK) inhibitor with potential antineoplastic activity. Linifanib inhibits members of the vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF) receptor families; it exhibits much less activity against unrelated RTKs, soluble tyrosine kinases, or serine/threonine kinases. This agent does not have a general antiproliferative effect due to its high dose requirement. However, linifanib may exhibit potent antiproliferative and apoptotic effects on tumor cells whose proliferation is dependent on mutant kinases, such as fms-related tyrosine kinase receptor-3 (FLT3).
- linoleyl carbonate-paclitaxel
- A formulation of the 6-omega fatty acid derivative 2’-linoleyl carbonate (LOC) conjugated to paclitaxel, a taxane compound extracted from the Pacific yew tree Taxus brevifolia, with potential antineoplastic activity. Paclitaxel binds to and stabilizes tubulin, thereby interfering with the dynamics of microtubule assembly/disassembly and resulting in the inhibition of cell division. LOC enhances the uptake of paclitaxel by tumor cells, thereby concentrating this agent in tumor cells compared to normal cells, and may decrease its toxicity profile; fatty acids serve as energy sources and biochemical precursors for the fast growing tumor cells.
- Linomide
- (Other name for: roquinimex)
- linperlisib
- An orally available selective inhibitor of the delta form of phosphatidylinositol 3-kinase (PI3-kinase subunit delta; PI3K-delta; PI3Kdelta), with potential antineoplastic activity. Upon oral administration linperlisib selectively binds to and inhibits PI3K-delta and prevents the activation of the PI3K/AKT signaling pathway. This decreases proliferation of and induces cell death in PI3K-delta over-expressing tumor cells. PI3K-delta also plays a key role in the B-cell receptor (BCR) signaling pathway and the proliferation of certain hematologic cancer cells. The targeted inhibition of PI3K-delta is designed to preserve PI3K signaling in normal, non-neoplastic cells, thereby minimizing serious side effects.
- linrodostat
- An orally available inhibitor of indoleamine 2,3-dioxygenase 1 (IDO1), with potential immunomodulating and antineoplastic activities. Upon administration, linrodostat specifically targets and binds to IDO1, a cytosolic enzyme responsible for the oxidation of the amino acid tryptophan into the immunosuppressive metabolite kynurenine. By inhibiting IDO1 and decreasing kynurenine in tumor cells, BMS-986205 restores and promotes the proliferation and activation of various immune cells, including dendritic cells (DCs), natural killer (NK) cells, and T lymphocytes, and causes a reduction in tumor-associated regulatory T cells (Tregs). Activation of the immune system, which is suppressed in many cancers, may induce a cytotoxic T-lymphocyte (CTL) response against the IDO1-expressing tumor cells, thereby inhibiting the growth of IDO1-expressing tumor cells. IDO1, overexpressed by multiple tumor cell types, plays an important role in immunosuppression. Tryptophan depletion inhibits T-lymphocyte proliferation and activation, and subsequently suppresses the immune system.
- linsitinib
- An orally bioavailable small molecule inhibitor of the insulin-like growth factor 1 receptor (IGF-1R) with potential antineoplastic activity. Linsitinib selectively inhibits IGF-1R, which may result in the inhibition of tumor cell proliferation and the induction of tumor cell apoptosis. Overexpressed in a variety of human cancers, IGFR-1 stimulates cell proliferation, enables oncogenic transformation, and suppresses apoptosis.
- lintuzumab
- A humanized recombinant monoclonal antibody directed against CD33, a cell surface antigen found on myeloid leukemia blasts and early hematopoietic progenitor cells. Lintuzumab stimulates antibody-dependent cell-mediated cytotoxicity (ADCC) against tumor cells expressing CD33, resulting in a decrease in tumor burden. The humanized version of this monoclonal antibody exhibits less immunogenicity and improved binding affinity compared to its murine counterpart.
- linvoseltamab
- A human, immunoglobulin G4 (IgG4) bispecific antibody directed against the tumor-associated antigen (TAA) human B-cell maturation antigen (BCMA; tumor necrosis factor receptor superfamily member 17; TNFRSF17) and the T-cell surface antigen CD3, with potential immunostimulating and antineoplastic activities. Upon administration, linvoseltamab targets and binds to both CD3 on cytotoxic T lymphocytes (CTLs) and BCMA on BCMA-expressing tumor cells. This activates and redirects CTLs to BCMA-expressing tumor cells, leading to CTL-mediated killing of BCMA-expressing tumor cells. BCMA, a member of the tumor necrosis factor receptor superfamily that is specifically overexpressed on malignant plasma cells, plays a key role in promoting plasma cell survival.
- linzagolix
- An orally bioavailable gonadotropin-releasing hormone (GnRH or LHRH) receptor antagonist, with potential hormone production inhibitory activity. Upon oral administration of linzagolix, this agent competes with GnRH for receptor binding and inhibits GnRH receptor signaling in the anterior pituitary gland, thereby inhibiting the secretion and release of luteinizing hormone (LH) and follicle stimulating hormone (FSH). In males, the inhibition of LH secretion prevents the release of testosterone. As a result, this may relieve symptoms associated with hormonally dependent disease states such as hormone-dependent prostate cancer. In women, this prevents the production of estrogen by the ovaries and may relieve symptoms from sex-hormone dependent diseases, such as pain associated with endometriosis, heavy menstrual bleeding or uterine fibroids.
- Linzess
- (Other name for: linaclotide acetate)
- Lioresal
- (Other name for: baclofen)
- liothyronine sodium
- The sodium salt form of liothyronine, a synthetic form of the levorotatory isomer of the naturally occurring thyroid hormone triiodothyronine (T3). Liothyronine sodium binds to nuclear thyroid receptors which then bind to thyroid hormone response elements of target genes. As a result, liothyronine sodium induces gene expression that is required for normal growth and development. Liothyronine sodium is more potent and has a more rapid action than thyroxine (T4).
- lipegfilgrastim
- A long acting glyco-pegylated recombinant form of human granulocyte colony-stimulating factor (G-CSF), with hematopoietic activity. Similar to G-CSF, lipegfilgrastim binds to and activates specific cell surface receptors, and stimulates neutrophil progenitor proliferation and differentiation. Therefore, this agent may prevent the duration and incidence of chemotherapy-induced neutropenia. Compared to filgrastim, lipegfilgrastim has a prolonged plasma half-life.
- Lipid Nanoparticle Encapsulated mRNA Encoding Human Single-chain IL-12 ABO2011
- A formulation consisting of lipid nanoparticle (LNP)-encapsulated messenger RNA (mRNA) encoding human single-chain interleukin-12 (scIL-12), with potential immunomodulatory and antineoplastic activities. Upon intratumoral injection, the LNP moiety binds to the plasma membrane of nearby cells and releases the scIL-12 mRNA into the cells. The mRNA is then translated by the cellular protein translation machinery to produce scIL-12, which is secreted into the local tumor microenvironment (TME).

This may prevent radiation-induced dermatitis as well as other types of skin reactions.
- liposome-encapsulated TAAs mRNA vaccine W_ova1
- A vaccine consisting of messenger RNA (mRNA) encoding three tumor-associated antigens (TAAs) specific for ovarian cancer that are encapsulated in liposomes, with potential immunomodulating and antineoplastic activities. Upon administration of the liposome-encapsulated TAAs mRNA vaccine W_ova1, the liposomes bind to the plasma membrane of cells and release the mRNA into the cells. The mRNA is then translated by ribosomes to produce the TAAs. The TAAs are presented to the immune system which may activate both humoral and cellular immune responses against the ovarian cancer cells expressing these TAAs.
- liposome-incorporated Grb2 antisense oligodeoxynucleotide
- A liposomal formulation containing the antisense oligodeoxynucleotide (ODN) growth factor receptor-bound protein 2 (Grb2), with potential antineoplastic activity. Upon administration, liposome-incorporated Grb2 antisense oligodeoxynucleotide binds directly to and blocks Grb2 mRNA, thereby preventing Grb2 protein synthesis, leading to inhibition of cell proliferation of cancer cells overexpressing Grb2. Grb2, an adaptor protein involved in growth signaling pathways, is upregulated in certain tumor cells.
- Lipotecan
- (Other name for: camptothecin analogue TLC388)
- Liquamar
- (Other name for: phenprocoumon)
- liraglutide
- A long-acting, fatty acylated glucagon-like peptide-1 (GLP-1) analog administered subcutaneously, with antihyperglycemic activity. Liraglutide's prolonged action and half-life of 11-15 hours are attributed to the attachment of the fatty acid palmitic acid to GLP-1 that reversibly binds to albumin. Albumin binding protects liraglutide from immediate degradation and elimination and causes GLP-1 to be released from abumin in a slow and consistent manner. This agent may cause thyroid C-cell tumors and increases the risk of acute pancreatitis.
- lirilumab
- A fully human monoclonal antibody against killer-cell immunoglobulin-like receptors (KIR), with potential antineoplastic activity. Upon administration, lirilumab binds to KIR, thereby preventing the binding of KIR ligands to KIR on natural killer (NK) cells.

Bcl-2 is overexpressed in many cancers and plays an important role in the negative regulation of apoptosis; its expression is associated with increased drug resistance and tumor cell survival.
- lisdexamfetamine dimesylate
- The dimesylate form and prodrug of the d-isomer of amphetamine, a non-catecholamine sympathomimetic amine with central nervous system (CNS) stimulating activity. Upon administration, lisdexamphetamine is converted to dextroamphetamine through cleavage of the lysine group. Dextroamphetamine acts by facilitating the release of catecholamines, particularly noradrenaline and dopamine, from its storage sites in nerve terminals in the CNS, and inhibits their uptake within the mesocorticolimbic system, a major component of the brain reward system, resulting in measurable behavioral changes such as euphoria, mental alertness and excitement and appetite suppression. As a CNS stimulant, this agent may increase blood pressure.
- lisinopril
- An orally bioavailable, long-acting angiotensin-converting enzyme (ACE) inhibitor with antihypertensive activity. Lisinopril, a synthetic peptide derivative, specifically and competitively inhibits ACE, which results in a decrease in the production of the potent vasoconstrictor angiotensin II and, so, diminished vasopressor activity. In addition, angiotensin II-stimulated aldosterone secretion by the adrenal cortex is decreased which results in a decrease in sodium and water retention and an increase in serum potassium.
- lisocabtagene maraleucel
- A preparation of a defined ratio of CD4+ and CD8+ autologous T lymphocytes transduced with a lentiviral vector expressing a chimeric antigen receptor (CAR) containing an anti-CD19 single chain variable fragment (scFv) fused to the signaling domain of 4-1BB (CD137), the zeta chain of the TCR/CD3 complex (CD3-zeta), and a truncated form of the human epidermal growth factor receptor (EGFRt), with potential immunostimulating and antineoplastic activities. Upon intravenous administration, lisocabtagene maraleucel is directed to and induces selective toxicity in CD19-expressing tumor cells. CD19 antigen is a B-cell specific cell surface antigen expressed in all B-cell lineage malignancies. Devoid of both ligand binding domains and tyrosine kinase activity, the expressed EGFRt both facilitates in vivo detection of the administered, transduced T cells and can promote elimination of those cells through a cetuximab-induced antibody dependent cellular cytotoxicity (ADCC) response. The 4-1BB costimulatory signaling domain enhances both proliferation of T cells and antitumor activity.

Upon administration of the Lm-LLO-PSA vaccine ADXS31-142, the expressed LLO-PSA is processed by antigen presenting cells (APCs), presented to the immune system by both major histocompatibility complex (MHC) I and II molecules, and activates the immune system to exert both an innate and adaptive immune response involving the recruitment and activation of T lymphocytes against PSA-expressing tumor cells as well as the inhibition of tumor-infiltrating T-regulatory cells (T regs) and myeloid-derived suppressor cells (MDSCs). This eventually results in tumor cell lysis.
- Lithane
- (Other name for: lithium carbonate)
- lithium carbonate
- The carbonate salt of lithium, a soft alkali metal, with antimanic and hematopoietic activities. Lithium interferes with transmembrane sodium exchange in nerve cells by affecting sodium, potassium-stimulated adenosine triphosphatase (Na+, K+-ATPase); alters the release of neurotransmitters; affects cyclic adenosine monophosphate (cAMP) concentrations; and blocks inositol metabolism resulting in depletion of cellular inositol and inhibition of phospholipase C-mediated signal transduction. The exact mechanism through which lithium exerts its mood-stabilizing effect has not been established. In addition, lithium stimulates granulocytopoiesis and appears to increase the level of pluripotent hematopoietic stem cells by stimulating the release of hematopoietic cytokines and/or directly acting on hematopoietic stem cells.

- live freeze-dried lactic acid bacteria probiotic
- A probiotic containing live, cultivated, freeze-dried lactic acid bacteria with gastrointestinal (GI) protective, anti-inflammatory, immunomodulating and potential antitumor properties. Oral administration of probiotic bacteria help maintain adequate colonization of the GI tract and modulate the composition of the normal microflora. Upon colonization of the GI tract, the probiotic bacteria form a protective barrier, interfere with the attachment of pathogenic bacteria and other harmful substances and may bind to and degrade carcinogens. This may prevent inflammation and possibly cancer. In addition, these bacteria produce lactic acid, thereby creating an acidic environment that is unfavorable for pathogens.
- live-attenuated double-deleted Listeria monocytogenes bacteria JNJ-64041809
- A proprietary, live-attenuated, double-deleted (LADD) strain of the Gram-positive bacterium Listeria monocytogenes (Lm) encoding multiple, as of yet undisclosed, tumor-associated antigens (TAAs), with potential immunostimulatory and antineoplastic activities. Upon intravenous administration, live-attenuated double-deleted Listeria monocytogenes bacteria JNJ-64041809 is taken up by antigen-presenting cells (APCs), including dendritic cells (DCs). The TAAs are subsequently expressed by the APCs and then processed and presented to the immune system by both major histocompatibility complex (MHC) class I and II molecules. This activates the immune system and leads to the recruitment and activation of cytotoxic T lymphocytes (CTLs) against the TAA-expressing tumor cells, eventually resulting in tumor cell lysis. Two genes contributing to the virulence of Lm have been removed to minimize the risk of infection.
- live-attenuated Listeria monocytogenes encoding EGFRvIII-NY-ESO-1 vaccine ADU-623
- A live-attenuated, double-deleted strain of the Gram-positive bacterium Listeria monocytogenes (Lm) encoding a mutant form of the tumor-associated antigens, epidermal growth factor receptor (EGFRvIII) and the cancer/testis antigen NY-ESO-1, with potential immunostimulatory and antineoplastic activities. Upon intravenous administration, live-attenuated Listeria monocytogenes encoding EGFRvIII-NY-ESO-1 vaccine targets dendritic cells and expresses EGFRvIII and NY-ESO-1. This promotes both a potent innate immune response and an adaptive immune response involving the recruitment and activation of T lymphocytes against EGFRvIII and NY-ESO-1-expressing tumor cells, which results in tumor cell lysis.
- live-attenuated listeria-encoding human mesothelin vaccine CRS-207
- A recombinant Listeria-based cancer vaccine containing a live-attenuated strain of the facultative intracellular bacterium Listeria monocytogenes (Lm) expressing human mesothelin with potential immunostimulatory and antineoplastic activities. Upon administration of this vaccine, Listeria invade professional phagocytes within the immune system and express mesothelin, which may activate a cytotoxic T-lymphocyte (CTL) response against mesothelin-expressing tumor cells, resulting in tumor cell lysis. In addition, the Listeria vector itself may induce a potent innate and adaptive immunity unrelated to mesothelin expression. Mesothelin is a cell surface glycoprotein involved in cell adhesion and is overexpressed in many epithelial-derived cancers, including pancreatic, ovarian and lung cancers, and malignant mesotheliomas.
- liver cancer neoantigens-sensitized autoimmune cells IPM001
- A preparation of autoimmune cells that have been sensitized to liver cancer neoantigens, with potential immunostimulating and antineoplastic activities, Upon administration of the liver cancer neoantigens-sensitized autoimmune cells IPM001, these cells may eradicate the liver cancer cells.
- livmoniplimab
- A humanized monoclonal antibody directed against the transforming growth factor beta (TGFbeta) activator, glycoprotein A repetitions predominant (GARP; leucine-rich repeat-containing protein 32; LRRC32), with potential immunomodulating and antineoplastic activities. Upon administration, livmoniplimab selectively targets and binds to GARP which interferes with the production and release of active TGFbeta by regulatory T cells (Tregs). Selective inhibition of the release of TGFbeta from Tregs leads to a reversal of immunosuppression thereby increasing the immune response to tumor cells. GARP, a leucine-rich repeat-containing protein, is essential for the expression of TGFbeta on the cell surface of activated Tregs; it plays an important role in regulation of the immune cell function.
- lixumista acetate
- The acetate salt form of lixumistat, an orally bioavailable biguanide compound and mitochondrial oxidative phosphorylation (OxPhos) inhibitor, with potential antineoplastic activity. Upon administration, lixumistat inhibits oxidative phosphorylation, decreases mitochondrial function, prevents tumor cell metabolism and deprives tumor cells of energy, thereby preventing tumor cell proliferation. Mitochondrial OxPhos is overactivated in cancer cells and plays a key role in tumor cell proliferation. Drug resistant tumor cells are very susceptible to decreased mitochondrial OxPhos as they cannot easily compensate for the decrease in mitochondrial function by increasing glycolysis.
- Lm-tLLO-neoantigens vaccine ADXS-NEO
- A proprietary, personalized plasmid DNA-based cancer vaccine composed of a live-attenuated strain of the Gram-positive bacterium Listeria monocytogenes (Lm) carrying a proprietary plasmid vector encoding multiple, patient-specific, immunogenic neoepitopes fused to a truncated form of the immunostimulant listeriolysin O (tLLO), with potential immunostimulatory and antineoplastic activities. Upon administration of the Lm-tLLO-neoantigens vaccine ADXS-NEO, the ADXS-NEO is taken up by antigen presenting cells (APCs), such as dendritic cells (DCs), and the expressed tLLO-neoantigens fusion protein is processed and presented to the immune system by both major histocompatibility complex (MHC) I and II molecules. This activates the immune system to exert both innate and adaptive immune responses involving the recruitment and activation of T lymphocytes against the tumor-associated antigens (TAAs) specifically expressed by the patient's tumor cells, and inhibits the immunosuppressive tumor-infiltrating T-regulatory cells (Tregs) and myeloid-derived suppressor cells (MDSCs) within the tumor microenvironment (TME). This results in tumor cell lysis. The various unique mutation-derived TAAs that are used in ADXS-NEO are identified from a biopsy of the patient's tumor.

- LMB-2 immunotoxin
- A fusion protein consisting of the Fv portion of a monoclonal antibody attached to a 38-kDa fragment of the Pseudomonas exotoxin A (with amino acids 365-380 deleted). LMB-2 immunotoxin targets the interleukin 2 receptor (also known as IL-2R or CD25) which is expressed on activated normal T and B cells and macrophages and on the cells of various hematologic malignancies. The antibody attaches to the IL-2R on the cell membrane, facilitating the entry of the exotoxin. The exotoxin moiety induces caspase-mediated apoptosis of tumor cells via a mechanism involving mitochondrial damage; it also catalyzes the transfer of ADP ribose from nicotinamide adenine dinucleotide (NAD) to elongation factor-2 in eukaryotic cells, thereby inactivating elongation factor 2 and inhibiting protein synthesis.
- LMB-7 immunotoxin
- A single chain chimeric protein consisting of a monoclonal antibody fragment attached to a portion of the Pseudomonas exotoxin A.

The exotoxin moiety induces caspase-mediated apoptosis of tumor cells via a mechanism involving mitochondrial damage; it also catalyzes the transfer of ADP ribose from nicotinamide adenine dinucleotide (NAD) to elongation factor-2 in eukaryotic cells, thereby inactivating elongation factor 2 and inhibiting protein synthesis.
- LmddA-LLO-chHER2 fusion protein-secreting live-attenuated Listeria cancer vaccine ADXS31-164
- A cancer vaccine containing a live, highly attenuated strain of the Gram-positive bacterium Listeria monocytogenes (LmddA) encoding a fusion protein composed of a chimeric peptide comprised of three highly immunogenic epitopes of the human tumor-associated antigen (TAA) HER2/neu (chHER2) fused to a non-hemolytic fragment of the immunostimulant listeriolysin O (LLO) protein, with potential immunostimulatory and antineoplastic activities. Upon administration of the LmddA-LLO-chHER2 vaccine ADXS31-142, the LmddA is taken up by phagocytic cells; then the listeriolysin portion of the expressed LLO-chHER2 can form pores in the phagolysosomes and the fusion protein can escape into the cytosol. In turn, the LLO-chHER2 is processed and presented to the immune system by major histocompatibility complex (MHC) I on the phagocytic cells. Antigen presentation activates the immune system to exert an immune response involving the recruitment and activation of T ymphocytes against HER2-expressing tumor cells, and inhibits tumor-infiltrating T-regulatory cells (Tregs) and myeloid-derived suppressor cells (MDSCs). This eventually results in tumor cell lysis. HER2/neu, a tyrosine kinase receptor belonging to the epidermal growth factor receptor (EGFR) family, is overexpressed in various tumor cell types.

- A preparation of T lymphocytes that have been genetically modified to encode a T-cell receptor (TCR) specific for Epstein-Barr virus (EBV) latent membrane protein (LMP) 2, with potential antineoplastic activity. Upon administration, the LMP2-specific IL-12 secreting TCR-transduced T lymphocytes (TCR-T) recognize and bind to EBV LMP2, which may promote cell death and inhibit the growth of tumor cells expressing LMP2. In addition, IL-12 expression activates the immune system by promoting the secretion of interferon-gamma, activating natural killer cells (NKs), and inducing cytotoxic T-cell responses, which may result in both decreased cell proliferation and increased cell death in LMP2-expressing tumor cells. As a tumor associated antigen (TAA), LMP2 is expressed in various EBV-associated malignancies including nasopharyngeal cancer and EBV-positive Hodgkin lymphoma.
- LMP2-specific T-cell receptor-transduced autologous T lymphocytes
- A preparation of autologous T lymphocytes that have been genetically modified to express a T-cell receptor (TCR) specific for the Epstein-Barr virus (EBV) latent membrane protein (LMP) 2, with potential immunomodulating and antineoplastic activities.

- A preparation of cytotoxic T-lymphocytes (CTL), specifically reactive to Epstein-Barr virus (EBV) latent membrane protein-2A (LMP2A), with potential antineoplastic activity. T-lymphocytes are exposed ex vivo to dendritic cells (DCs) transfected with a replication-deficient adenovirus encoding EBV LMP2A. Subsequently, LMP2A-specific CTLs are exposed to EBV infected cells transfected with adenovirus encoding LMP2A, thereby further stimulating CTLs. Administered to patients with EBV-positive tumors, LMP2A-specific CTLs target LMP2A-positive cells, resulting in cell lysis and inhibition of cancer cell proliferation. EBV LMP2A may be expressed in various malignancies, including nasopharyngeal carcinoma and Hodgkin and non-Hodgkin lymphomas.
- LMP7 inhibitor M3258
- An orally bioavailable, potent, selective, reversible inhibitor of the large multifunctional peptidase 7 (LMP7, Beta5i, PSMB8), a chymotrypsin-like, proteolytic subunit of the immunoproteasome, with potential antineoplastic activity. Upon oral administration, LMP7 inhibitor M3258 targets and inhibits the proteolytic activity of the LMP7 subunit of immunoproteasome, thereby blocking its deubiquitylating activity. This blocks the ubiquitin proteasome degradation pathway, prevents the degradation of defective proteins, and leads to an accumulation of poly-ubiquitylated proteins. This induces the unfolded protein response (UPR) and results in both the induction of tumor cell apoptosis and the inhibition of tumor cell growth. Proteasomes are large multi-subunit protease complexes that degrade unneeded or damaged proteins that have been ubiquitinated, thereby restoring protein homeostasis. Unlike the constitutive proteasome, which is expressed in most tissues, immunoproteasome is specifically present in normal and malignant hematopoietic cells, including multiple myeloma. Immunoproteasome degrades ubiquitinated proteins, generates peptides for presentation on MHC class I, and plays a key role in the adaptive immune response and inflammatory diseases.
- lobaplatin
- A third-generation, water-soluble platinum compound with potential antineoplastic activity. Lobaplatin forms highly reactive, charged, platinum complexes that bind to nucleophilic groups such as GC- and AG-rich sites in DNA, inducing intrastrand DNA cross-links. These cross-links will ultimately result in induction of apoptosis and cell growth inhibition. Compared to first and second generation platinum compounds, lobaplatin appears to be more stable, less toxic, have a better therapeutic index and may overcome tumor resistance.
- lobradimil
- A synthetic analog of bradykinin. Lobradimil is a potent, specific bradykinin B-2 receptor agonist that stimulates B-2 receptors expressed on the surface of brain capillary endothelial cells, thereby reversibly increasing the permeability of the blood-brain barrier (BBB). Compared to bradykinin, this agent possesses enhanced receptor selectivity, greater plasma stability, and a longer half-life.
- locally-acting temozolomide formulation SI-053
- A powder for gel formulation containing the cytotoxic alkylating agent temozolomide (TMZ), an imidazotetrazine derivative of the alkylating agent dacarbazine, immobilized on the polymeric carrier dextran phosphate, with potential antineoplastic activity. The TMZ formulation SI-053 forms a viscous gel upon reconstitution in water. Upon local intraoperative administration of the gel into the cavity that is formed after resection of the brain tumor, SI-053 allows for local and prolonged action of TMZ. TMZ is converted at physiologic pH to the short-lived active compound 5-(3-methyl-(triazen-1-yl)-imidazole)-4-carboxamide (monomethyltriazenoimidazole carboxamide; MTIC). The cytotoxicity of MTIC is due to methylation of DNA, particularly at the O6 and N7 positions of guanine residues, resulting in cell cycle arrest, inhibition of DNA replication and the induction of apoptosis. The local administration of TMZ allows for the local destruction of the remaining tumor cells immediately after the removal of the tumor and may prevent the recurrence of tumor growth while having no severe systemic toxicity.
- lodapolimab
- A monoclonal antibody directed against programmed cell death-1 ligand 1 (PD-L1) with immune checkpoint inhibitory and potential antineoplastic activities. Upon administration, lodapolimab binds to PD-L1 and prevents the interaction of PD-L1 with its receptor programmed cell death protein 1 (PD-1). This inhibits the activation of PD-1 and its downstream signaling pathways, which may enhance the T-cell-mediated immune response to neoplasms and reverse T-cell inactivation. PD-L1 is overexpressed by many human cancer cell types. PD-L1 binding to PD-1 on T cells suppresses the immune system and results in immune evasion. PD-1, a transmembrane protein expressed on activated T cells, is a negative regulator of the immune system that limits the expansion and survival of CD8+ T cells.
- Lodine
- (Other name for: etodolac)
- Lodosyn
- (Other name for: carbidopa)
- lometrexol
- A folate analog antimetabolite with antineoplastic activity. As the 6R diastereomer of 5,10-dideazatetrahydrofolate, lometrexol inhibits glycinamide ribonucleotide formyltransferase (GARFT), the enzyme that catalyzes the first step in the de novo purine biosynthetic pathway, thereby inhibiting DNA synthesis, arresting cells in the S phase of the cell cycle, and inhibiting tumor cell proliferation. The agent has been shown to be active against tumors that are resistant to the folate antagonist methotrexate.
- lomonitinib
- An orally bioavailable inhibitor of FMS-like tyrosine kinase 3 (FLT3; CD135; STK1; FLK2) mutations and interleukin-1 receptor-associated kinase 4 (IRAK4), with potential antineoplastic activity. Upon oral administration, lomonitinib targets, binds to and inhibits the activity of FLT3 mutations, including the FLT3-ITD-F691L gatekeeper mutation, while sparing the wild-type form of FLT3. This inhibits the proliferation of FLT3 mutant-expressing cancer cells. In addition, lomonitinib targets, binds to, and inhibits the kinase activity of IRAK4. This inhibits IRAK4-mediated signaling and may reduce adaptive resistance to FLT3 inhibition as toll-like receptor (TLR) activation plays an important role in resistance to FLT3 inhibition. FLT3, a class III receptor tyrosine kinase (RTK), is overexpressed or mutated in most B-lineage neoplasms and in acute myeloid leukemias. IRAK4, a serine/threonine-protein kinase, plays a key role in both the TLR and IL-1R signaling pathways.
- Lomotil
- (Other name for: diphenoxylate hydrochloride/atropine sulfate)
- lomustine
- A nitrosourea with antineoplastic activity. Lomustine alkylates and crosslinks DNA, thereby inhibiting DNA and RNA synthesis. This agent also carbamoylates DNA and proteins, resulting in inhibition of DNA and RNA synthesis and disruption of RNA processing. Lomustine is lipophilic and crosses the blood-brain barrier.
- lomvastomig
- A bispecific antibody directed against both the negative immunoregulatory human cell receptor programmed cell death protein 1 (PD-1; PDCD1; CD279) and the inhibitory T-cell receptor T-cell immunoglobulin and mucin domain-containing protein 3 (TIM-3; TIM3; hepatitis A virus cellular receptor 2; HAVCR2), with potential immune checkpoint inhibitory and antineoplastic activities. Upon administration, lomvastomig simultaneously targets and binds to both TIM-3 and PD-1 expressed on certain T cells. This blocks the interaction of TIM-3 with some of its physiologic ligands and prevents the activation of PD-1 by its ligands, programmed cell death-1 ligand 1 (PD-L1) or 2 (PD-L2). This abrogates T-cell inhibition, activates antigen-specific T lymphocytes and enhances cytotoxic T-cell-mediated tumor cell lysis, which may lead to a reduction in tumor growth. TIM-3, a transmembrane protein and immune checkpoint receptor, is often co-expressed with PD-1 on tumor-antigen-specific T cells. Dual checkpoint blockade of PD-1 and TIM-3 may enhance T-cell activation and proliferation more than the blockade of either immune checkpoint receptor alone.
- lonafarnib
- A synthetic tricyclic derivative of carboxamide with antineoplastic properties. Lonarfanib binds to and inhibits farnesyl transferase, an enzyme involved in the post-translational modification and activation of Ras proteins.

Mutated ras proteins have been found in a wide range of human cancers.
- lonaprisan
- An orally bioavailable pentafluoroethyl derivative of a mifepristone-related steroid with antiprogestagenic activity. Lonaprisan is a pure, highly receptor-selective progesterone receptor (PR) antagonist; binding of this agent to PRs inhibits PR activation and the associated proliferative effects. Unlike many other antiprogestins such as mifepristone, this agent does not appear to convert to an agonist in the presence of protein kinase A (PKA) activators and shows high antiprogestagenic activity on both progesterone receptor (PR) isoforms PR-A and PR-B.
- loncastuximab tesirine-lpyl
- An antibody-drug conjugate (ADC) consisting of an anti-CD19 humanized monoclonal antibody conjugated, via a cleavable linker comprised of valine-alanine and maleimide, to a cytotoxic, cross-linking agent pyrrolobenzodiazepine (PBD) dimer, which targets DNA minor grooves, with potential antineoplastic activity. Upon administration, the monoclonal antibody portion of loncastuximab tesirine targets the cell surface antigen CD19 on various cancer cells. Upon antibody/antigen binding and internalization, the cytotoxic PBD moiety is released. The imine groups of the PBD moiety bind to the N2 positions of guanines on opposite strands of DNA. This induces interstrand cross-links in the minor groove of DNA and inhibits DNA replication, which inhibits the proliferation of CD19-overexpressing tumor cells. CD19, a transmembrane receptor and tumor-associated antigen (TAA), is expressed on a number of B-cell-derived cancers.
- long PD-L1 peptide vaccine
- A peptide cancer vaccine composed of a long peptide, containing amino acids 19 through 27 (FMTYWHLLNAFTVTVPKDL), obtained from the tumor-associated antigen (TAA) and immune checkpoint molecule programmed cell death-1 ligand 1 (PD-L1), with potential immunomodulating and antineoplastic activities. Upon vaccination with long PD-L1 peptide vaccine, the peptide may activate the immune system to induce an immune response against PD-L1-expressing cells. This may induce a cytotoxic T-lymphocytes (CTLs)-mediated immune response against PD-L1-expressing tumor cells. PD-L1 is overexpressed on many human cancer cell types as well as on antigen presenting cells (APCs) and immunosuppressive cells in the tumor micro-environment (TME), such as regulatory T cells (Tregs). PD-L1 binding to its cognate receptor programmed cell death protein 1 (PD-1; PDCD1; CD279) on T cells suppresses the immune system and results in increased immune evasion and decreased CTL activation.
- long peptide vaccine 7
- A peptide vaccine consisting of a combination of seven synthetic long peptides (SLPs), which are each about 30 amino acids in size, and derived from cancer-testis antigens (CTA) and melanocytic differentiation proteins (MDP), with potential immunostimulating and antitumor activities. Upon administration, long peptide vaccine 7 may stimulate the host immune system to mount a cytotoxic T-cell lymphocyte (CTL) response against tumor cells expressing these peptides. CTA and MDP are overexpressed in a variety of cancer cell types.
- long-acting recombinant Erwinia asparaginase JZP341
- A long-acting and recombinant form of asparaginase (Erwinia asparaginase; crisantaspase), with potential antineoplastic activity. Upon administration of long-acting recombinant Erwinia asparaginase JZP-341, the recombinant asparaginase hydrolyzes L-asparagine to L-aspartic acid and ammonia. This depletes cancer cells of asparagine, which blocks protein synthesis and tumor cell proliferation. Asparagine is critical to protein synthesis in cancer cells, which cannot synthesize this amino acid due to the absence of the enzyme asparagine synthase.
- long-acting release pasireotide
- A long-acting release (LAR) formulation containing pasireotide, a synthetic long-acting cyclohexapeptide, with somatostatin-like activity. Upon intramuscular administration of the LAR formulation of pasireotide, this somatostatin analog strongly binds to and activates somatostatin receptor (SSTR) subtypes 1, 2, 3, and 5. This leads to an inhibition in the secretion of human growth hormone (hGH) and results in decreased production of insulin-like growth factor (IGF-1), which may inhibit IGF-1-mediated cell signaling pathways. This may lead to an inhibition in tumor cell growth and an increase in apoptosis in IGF-1-overexpressing tumor cells. In addition, this agent causes a reduction in adrenocorticotropic hormone (ACTH), which leads to an inhibition of cortisol secretion. ACTH-producing tumors cause hypersecretion of cortisol which results in many unwanted symptoms. This agent may also block other key survival pathways such as the phosphatidylinositol 3-kinase (PI3K) and the mitogen-activated protein kinase (MAPK) signaling pathways. Pasireotide also inhibits vascular endothelial growth factor (VEGF) secretion, thereby decreasing angiogenesis and tumor cell growth in VEGF-overexpressing tumor cells. The long-acting form of pasireotide allows for less frequent administration as compared to the original form of this agent. SSTRs are overexpressed by some neuroendocrine and non-neuroendocrine tumor cells.

- (Other name for: lipegfilgrastim)
- Lonsurf
- (Other name for: trifluridine and tipiracil hydrochloride)
- loperamide hydrochloride
- The hydrochloride salt form of loperamide, a synthetic, piperidine derivative and opioid agonist with antidiarrheal activity. Loperamide acts on the mu-receptors in the intestinal mucosa. This leads to a decrease in gastrointestinal motility by decreasing the circular and longitudinal smooth muscle activity of the intestinal wall. This slows intestinal transit and allows for more water and electrolyte absorption from the intestines. Loperamide is not significantly absorbed from the gut and does not cross the blood-brain barrier. Therefore it has no central nervous system effects.
- Lopid
- (Other name for: gemfibrozil)
- lopinavir
- A protease inhibitor used against human immunodeficiency virus (HIV). Lopinavir competitively inhibits the HIV-1 protease, an enzyme that mediates the cleavage of Gag, Gag-Pol and Nef precursor polypeptides into their mature proteins, including protease, reverse transcriptase, and integrase. Inhibition of HIV-1 protease prevents cleavage of the viral polyprotein precursor and results in the release of immature, noninfectious virions.

- loratadine
- A piperidine histamine H1-receptor antagonist with anti-allergic properties and without sedative effects. Loratadine blocks the H1 histamine receptor and prevents the symptoms that are caused by histamine activity on capillaries, bronchial smooth muscle, and gastrointestinal smooth muscle, including vasodilatation, increased capillary permeability, bronchoconstriction, and spasmodic contraction of gastrointestinal smooth muscle. Loratadine does not cross the blood-brain barrier and does not cause central nervous system effects.
- lorazepam
- A benzodiazepine with anxiolytic, anti-anxiety, anticonvulsant, anti-emetic and sedative properties. Lorazepam enhances the effect of the inhibitory neurotransmitter gamma-aminobutyric acid on the GABA receptors by binding to a site that is distinct from the GABA binding site in the central nervous system. This leads to an increase in chloride channel opening events, a facilitation of chloride ion conductance, membrane hyperpolarization, and eventually inhibition of the transmission of nerve signals, thereby decreasing nervous excitation.
- Lorbrena
- (Other name for: lorlatinib)
- Lorcet
- (Other name for: hydrocodone/acetaminophen)
- lorigerlimab
- A hinge stabilized immunoglobulin G4 (IgG4) tetravalent bispecific antibody-like protein directed against the human negative immunoregulatory checkpoint receptors programmed cell death protein 1 (PD-1; PDCD1; CD279) and cytotoxic T-lymphocyte-associated antigen 4 (CTLA4; CTLA-4), with potential immune checkpoint inhibitory and antineoplastic activities. Upon administration, lorigerlimab specifically binds to both PD-1 and CTLA4 expressed on tumor-infiltrating lymphocytes (TILs) and inhibits the PD-1- and CTLA4-mediated downregulation of T-cell activation and proliferation. Dual blockade of PD1 and CTLA4 pathways provides enhanced activity against PD1+CTLA4+ double positive cells and may increase T-cell activation and proliferation compared to the blockade of either immune checkpoint alone.
- lorlatinib
- An orally available, ATP-competitive inhibitor of the receptor tyrosine kinases, anaplastic lymphoma kinase (ALK) and C-ros oncogene 1 (Ros1), with potential antineoplastic activity. Upon administration, lorlatinib binds to and inhibits both ALK and ROS1 kinases. The kinase inhibition leads to disruption of ALK- and ROS1-mediated signaling and eventually inhibits tumor cell growth in ALK- and ROS1-overexpressing tumor cells. In addition, PF-06463922 is able to cross the blood brain barrier. ALK belongs to the insulin receptor superfamily and plays an important role in nervous system development; ALK dysregulation and gene rearrangements are associated with a series of tumors. ROS1, overexpressed in certain cancer cells, plays a key role in cell growth and survival of cancer cells.
- lorpucitinib
- An orally bioavailable pan-inhibitor of the Janus associated-kinases (JAKs), with potential immunomodulatory and anti-inflammatory activities. Upon oral administration, lorpucitinib works in the gastrointestinal (GI) tract where it targets, binds to and inhibits the activity of the JAKs, thereby disrupting JAK-signal transducer and activator of transcription (STAT) signaling pathways and the phosphorylation of STAT proteins. This may inhibit the release of pro-inflammatory cytokines and chemokines, reducing inflammatory responses and preventing inflammation-induced damage. The Janus kinase family of non-receptor tyrosine kinases, which includes tyrosine-protein kinase JAK1 (Janus kinase 1; JAK1), tyrosine-protein kinase JAK2 (Janus kinase 2; JAK2), tyrosine-protein kinase JAK3 (Janus kinase 3; JAK3) and non-receptor tyrosine-protein kinase TYK2 (tyrosine kinase 2), plays a key role in cytokine signaling and inflammaton.
- lorvotuzumab mertansine
- An immunoconjugate of a humanized murine monoclonal antibody (huN-901) and DMI, a semi-synthetic derivative of the plant-derived ansa macrolide maytansine. The antibody moiety of lorvotuzumab mertansine selectively attaches to CD56 antigen, a neural cell adhesion molecule (NCAM)) expressed on the surface of cells of small cell lung cancer (SCLC) and other neuroendocrine (NE) tumors. Thus, the DMI conjugate is targeted specifically to CD56-expressing tumor cells, where it inhibits tubulin polymerization and assembly, resulting in inhibition of mitosis and cell cycle arrest in the S phase.
- losartan
- A non-peptide angiotensin II antagonist with antihypertensive activity. Upon administration, losartan and its active metabolite selectively and competitively blocks the binding of angiotensin II to the angiotensin I (AT1) receptor. This blocks the vasoconstricting and aldosterone-secreting actions of angiotensin II, leading to a decrease in blood pressure. Angiotensin II, formed from angiotensin I by angiotensin-converting enzyme (ACE), stimulates the adrenal cortex to synthesize and secrete aldosterone, which decreases the excretion of sodium and increases the excretion of potassium. Angiotensin II also acts as a vasoconstrictor in vascular smooth muscle.
- losartan potassium
- The potassium salt of losartan, a non-peptide angiotensin II receptor antagonist with antihypertensive activity. Losartan selectively and competitively binds to the angiotensin II receptor (type AT1) and blocks the binding of angiotensin II to the receptor, thus promoting vasodilatation and counteracting the effects of aldosterone. Converted from angiotensin I by angiotensin-converting enzyme (ACE), angiotensin II stimulates the adrenal cortex to synthesize and secrete aldosterone, decreasing sodium excretion and increasing potassium excretion, and acts as a vasoconstrictor in vascular smooth muscle.
- Lotensin
- (Other name for: benazepril hydrochloride)
- Lotrimin
- (Other name for: clotrimazole)
- lovastatin
- A lactone metabolite isolated from the fungus Aspergillus terreus with cholesterol-lowering and potential antineoplastic activities. Lovastatin is hydrolyzed to the active beta-hydroxyacid form, which competitively inhibits 3-hydroxyl-3-methylgutarylcoenzyme A (HMG-CoA) reductase, an enzyme involved in cholesterol biosynthesis. In addition, this agent may induce tumor cell apoptosis and inhibit tumor cell invasiveness, possibly by inhibiting protein farnesylation and protein geranylgeranylation, and may arrest cells in the G1 phase of the cell cycle. The latter effect sensitizes tumor cells to the cytotoxic effects of ionizing radiation.
- Lovaxin C

Upon administration, LRP-1-targeted peptide-drug conjugate GRN1005, via angiopep-2 moiety, binds to LRP-1 (low density lipoprotein receptor-related protein 1), which is highly expressed in blood brain barrier (BBB) and glioma cells. This binding allows the transcytosis of the agent across the BBB and the delivery of the cytotoxic agent paclitaxel. Compared to paclitaxel alone, GRN1005 is able to increase the concentration of paclitaxel in the brain and is also able to specifically deliver paclitaxel to LRP-1-overexpressing tumor cells, both in the brain and in the periphery.
- LRP5 antagonist BI 905681
- An antagonist of the lipoprotein receptor-related protein (LRP) 5, with potential antineoplastic and immunomodulating activities. Upon administration, LRP5 antagonist BI 905681 targets and binds to LRP5, thereby blocking the binding of Wnt ligands to LRP5. This prevents the formation of the serpentine receptor Frizzled (FZD)-Wnt-LRP5 trimeric complex and prevents the inactivation of the beta-catenin degradation complex, which leads to beta-catenin degradation. This inhibits the Wnt/beta-catenin signaling pathway, prevents the beta-catenin-mediated activation of Wnt target genes, and inhibits the proliferation and survival of Wnt/beta-catenin-driven tumor cells. In addition, inhibition of Wnt signaling by BI 905681 prevents Wnt-mediated immune escape, thereby re-activating the immune system, specifically inducing the activation of dendritic cells (DCs) and activation as well as infiltration of cytotoxic T cells into the tumor tissue. The FZD-Wnt-LRP5 trimeric complex induces phosphorylation of LRP5 intracellular domain leading to inactivation of the beta-catenin degradation complex, allowing beta-catenin accumulation; stabilized beta-catenin enters the nucleus and acts as a transcriptional activator of Wnt target genes. Wnt/beta-catenin signaling plays a key role in tumor cell proliferation and survival, and resistance to immunotherapy.
- LRP5/6 antagonist BI 905677
- A humanized biparatopic nanobody composed of two blocking domains for the Wnt ligand co-receptors lipoprotein receptor-related proteins (LRP) 5 and 6, with potential antineoplastic and immunomodulating activities. Upon administration, BI 905677 targets and binds to LRP5 and LRP6, thereby blocking the binding of Wnt ligands to LRP5/6. This prevents the activation of the Frizzled (FZD)-Wnt-LRP5/6 trimeric complex and prevents the inactivation of the beta-catenin degradation complex, which leads to beta-catenin degradation. This inhibits the Wnt/beta-catenin signaling pathway, prevents the beta-catenin-mediated activation of Wnt target genes, and inhibits the proliferation and survival of Wnt-driven tumor cells. In addition, inhibition of Wnt signaling by BI 905677 prevents Wnt-mediated immune escape, thereby re-activating the immune system, specifically inducing the activation of dendritic cells (DCs) and activation as well as infiltration of cytotoxic T cells into the tumor tissue. The FZD-Wnt-LRP5/6 trimeric complex induces phosphorylation of LRP5 or LRP6 intracellular domains leading to inactivation of the beta-catenin degradation complex, allowing beta-catenin accumulation; stabilized beta-catenin enters the nucleus and acts as a transcriptional activator of Wnt target genes. Wnt/beta-catenin signaling plays a key role in tumorigenesis and resistance to immunotherapy.
- LSD1 inhibitor GSK2879552
- An orally available, irreversible, inhibitor of lysine specific demethylase 1 (LSD1), with potential antineoplastic activity. Upon administration, GSK2879552 binds to and inhibits LSD1, a demethylase that suppresses the expression of target genes by converting the dimethylated form of lysine at position 4 of histone H3 (H3K4) to mono- and unmethylated H3K4. LSD1 inhibition enhances H3K4 methylation and increases the expression of tumor-suppressor genes. This may lead to an inhibition of cell growth in LSD1-overexpressing tumor cells. LSD1, overexpressed in certain tumor cells, plays a key role in tumor cell growth and survival.
- LSD1 inhibitor SYHA1807
- An orally available inhibitor of lysine-specific demethylase 1 (LSD1; KDM1A), with potential antineoplastic activity. Upon oral administration, LSD1 inhibitor SYHA1807 targets, binds to and inhibits LSD1, a demethylase that suppresses the expression of target genes by converting the di- and mono-methylated forms of lysine at position 4 of histone 3 (H3K4) to mono- and unmethylated H3K4, respectively. LSD1 inhibition enhances H3K4 methylation and increases the expression of tumor suppressor genes. This may lead to an inhibition of cell growth in LSD1-overexpressing tumor cells. In addition, LSD1 demethylates mono- or di-methylated H3K9 which increases gene expression of tumor promoting genes; inhibition of LSD1 promotes H3K9 methylation and decreases transcription of these genes. LSD1 is overexpressed in a number of tumor cell types. LSD1 acts on histone H3 as a transcription co-repressor through demethylation of lysine 4 (H3K4) or as a transcription co-activator through demethylation of lysine 9 (H3K9).

- LSD1/HDAC6 inhibitor JBI-802
- An orally bioavailable inhibitor of two proteins that are part of the corepressor to the silencer repressor element 1 (RE1) silencing transcription factor (REST) complex (CoREST complex): histone deacetylase (HDAC) type 6 (HDAC6; HDAC-6) and lysine-specific demethylase 1 (LSD1; KDM1A), with potential antineoplastic activity. Upon oral administration, LSD1/HDAC6 inhibitor JBI-802 targets, binds to and inhibits the activity of HDAC6, and prevents the HDAC6-mediated aggresomal degradation of ubiquitinated proteins. This results in an accumulation of highly acetylated chromatin histones, the induction of chromatin remodeling and an altered pattern of gene expression. This results in a selective transcription of tumor suppressor genes, tumor suppressor protein-mediated inhibition of tumor cell division and an induction of apoptosis in tumor cells that overexpress HDAC6. It also modulates genes involved in immune suppression. In addition, JBI-802 specifically targets, binds to and inhibits LSD1, a demethylase that suppresses the expression of target genes by converting the di- and mono-methylated forms of lysine at position 4 of histone 3 (H3K4) to mono- and unmethylated H3K4, respectively. LSD1 inhibition enhances H3K4 methylation and increases the expression of tumor suppressor genes. This may lead to an inhibition of cell growth in LSD1-overexpressing tumor cells. In addition, LSD1 demethylates mono- or di-methylated H3K9 which increases gene expression of tumor promoting genes; inhibition of LSD1 promotes H3K9 methylation and decreases transcription of these genes. HDAC6, which is upregulated in many tumor cell types, deacetylates chromatin histone proteins. LSD1 is overexpressed in a number of tumor cell types.

- lucanthone
- An orally available thioxanthone-based DNA intercalator and inhibitor of the DNA repair enzyme apurinic-apyrimidinic endonuclease 1 (APEX1 or APE1), with anti-schistosomal and potential antineoplastic activity. Lucanthone intercalates DNA and interferes with the activity of topoisomerases I and II during replication and transcription, thereby inhibiting the synthesis of macromolecules. In addition, this agent specifically inhibits the endonuclease activity of APE1, without affecting its redox activity, resulting in unrepaired DNA strand breaks which may induce apoptosis. Therefore, lucanthone may sensitize tumor cells to radiation and chemotherapy. Furthermore, lucanthone inhibits autophagy through the disruption of lysosomal function. The multifunctional nuclease APE1 is a key component for DNA repair; its expression is often correlated with tumor cell resistance to radio- and chemotherapy.

- Ludiomil
- (Other name for: maprotiline hydrochloride)
- Lugol's solution
- A solution composed of iodine and potassium iodide, which can be used as a reagent and antiseptic, with potential use in cancer diagnosis. The iodine in Lugol’s solution selectively binds to alpha-1,4 glucans found in polysaccharides, such as glycogen. Lugol’s solution reacts with glycogen in normal, healthy non-keratinized, squamous epithelium and the iodine-glucan complex stains the glycogen-containing cells dark brown. Cancer cells are devoid of glycogen, so these cells will stay unstained. The presence of cancer cells can be detected by the degree of staining and the neoplastic cells can be surgically removed. High-grade intraepitheial neoplasia has almost no glycogen-containing epithelium.

- lung-targeted immunomodulator QBKPN
- A proprietary, lung-targeted, site specific immunomodulator (SSI), with potential immunostimulating and antineoplastic activities. Although the exact type and composition of the lung-targeted immunomodulator QBKPN has yet to be fully disclosed, upon subcutaneous administration, this agent is able to activate a local innate immune response in the lung tissue. This results in an increased number of M1 macrophages, which induces a shift from M2 to M1 macrophage dominance in the tumor microenvironment, and stimulates the recruitment of other immune cells. The M1 macrophages exert antitumor activity and eradicate lung cancer cells through phagocytosis. QBKPN does not induce a systemic immune response or affect other organs or tissues. Altogether, this SSI may decrease tumor cell growth in the lungs. SSIs contain specific, inactivated components of pathogens, such as bacteria and/or viruses, which normally cause an acute infection in the specific organ or tissue of interest.
- lunresertib
- An orally bioavailable inhibitor of the human membrane-associated tyrosine- and threonine-specific cdc2-inhibitory kinase (PKMYT1), with potential antineoplastic activity. Upon oral administration, lunresertib targets, binds to and inhibits the activity of PKMYT1. This results in the inhibition of CDK1 phosphorylation, which may promote both premature mitosis and a prolonged mitotic arrest, and lead to the accumulation of unrepaired DNA damage and apoptosis in susceptible tumor cells, such as CCNE1-overexpressing tumor cells. PKMYT1 phosphorylates CDK1 specifically when CDK1 is complexed to cyclins, which blocks progression from G2 into mitosis.
- Lunsumio

- lurtotecan
- A semisynthetic analogue of camptothecin with antineoplastic activity. Lurtotecan selectively stabilizes the topoisomerase I-DNA covalent complex and forms an enzyme-drug-DNA ternary complex. As a consequence of the formation of this complex, both the initial cleavage reaction and religation steps are inhibited and subsequent collision of the replication fork with the cleaved strand of DNA results in inhibition of DNA replication, double strand DNA breakage and triggering of apoptosis. Independent from DNA replication inhibition, lurtotecan also inhibits RNA synthesis, multi-ubiquitination and degradation of topoisomerase I and chromatin reorganization.
- luspatercept-aamt
- A soluble, recombinant fusion protein composed of a modified form of the extracellular domain of human activin receptor type IIb (ActRIIb) and linked to the human IgG1 Fc domain, with red blood cell stimulating activity. Upon subcutaneous administration, luspatercept-aamt inhibits several ligands in the transforming growth factor (TGF)-beta superfamily. This prevents activation of a variety of TGF-beta superfamily members involved in late stage erythropoiesis and results in an increased differentiation and proliferation of erythroid progenitors. Luspatercept-aamt acts at a different, later stage than erythropoietin. This agent ultimately enhances red blood cell production and prevents anemia.

The antibody moiety of Lu 177 anti-CA19-9 monoclonal antibody 5B1 targets and binds to CA19-9-expressing tumor cells. This may promote killing of CA19-9-expressing tumor cells through the local induction of both complement-dependent cytotoxicity (CDC) and antibody-dependent cell-mediated cytotoxicity (ADCC). Additionally, upon binding and internalization, the Lu 177 moiety can deliver a cytotoxic dose of beta radiation to the CA19-9-expressing tumor cells. Furthermore, the radioisotope moiety may be imaged using planar imaging and SPECT, thus allowing evaluation of the pharmacokinetic profile of the agent, and the imaging and quantification of CA19-9-expressing tumor cells, respectively. CA19-9, a Lewis-type carbohydrate antigen overexpressed on a number of different tumor cell types, plays a key role in tumor cell survival and metastasis.

This enhances neutrophils, monocytes and lymphocyte tumor infiltration and increases the production of key immune mediators, including interleukins IL-6, IL-8, IL-12, interferon (IFN)-gamma and tumor necrosis factor (TNF)-alpha, and vascular endothelial growth factor (VEGF), thereby inducing antitumor immune responses. TARA-002 is based on the same master cell bank of genetically distinct group A Streptococcus pyogenes as OK-432.

- lysine-specific demethylase 1 inhibitor INCB059872
- An orally available inhibitor of lysine-specific demethylase 1 (LSD1; lysine-specific histone demethylase 1A; KDM1A), with potential antineoplastic activity. Upon administration, INCB059872 binds to and inhibits LSD1, a demethylase that suppresses the expression of target genes by converting the di- and mono-methylated forms of lysine at position 4 of histone H3 (H3K4) to mono- and unmethylated H3K4, respectively, through amine oxidation. LSD1 inhibition enhances H3K4 methylation and increases the expression of tumor-suppressor genes. In addition, LSD1 demethylates mono- or di-methylated H3K9 which increases gene expression of tumor promoting genes; inhibition of LSD1 promotes H3K9 methylation and decreases transcription of these genes. Altogether, this may lead to an inhibition of cell growth in LSD1-overexpressing tumor cells. LSD1, an enzyme belonging to the flavin adenine dinucleotide (FAD)-dependent amine oxidase family, is overexpressed in certain tumor cells and plays a key role in the regulation of gene expression and in tumor cell growth and survival.
- lyso-thermosensitive liposomal doxorubicin
- A temperature-sensitive liposomal formulation of the anthracycline antibiotic doxorubicin with potential antineoplastic activity. Upon intravenous administration, circulating thermosensitive liposomes are activated locally by increasing the tumor temperature to 40-41 degrees Celsius using an external heat source. The elevated temperature causes compositional changes in the liposomes, creating openings that allow for the release of encapsulated doxorubicin. Compared to non-thermosensitive liposomes, lyso-thermosensitive liposomes deliver higher concentrations of a cytotoxic agent to a heat-treated tumor site while sparing normal tissues unexposed to heat treatment.
