- Raf kinase inhibitor HM95573
An orally available inhibitor of members of the Raf family of serine/threonine protein kinases, with potential antineoplastic activity. Upon administration, Raf kinase inhibitor HM95573 binds to and inhibits the B-Raf mutant V600E and C-Raf. This inhibits B-Raf V600E- and C-Raf-mediated signal transduction pathways, thereby inhibiting tumor cell growth of susceptible tumor cells. In addition, HM95573 may also inhibit mutated Ras proteins. Raf protein kinases play a key role in the Raf/mitogen-activated protein kinase kinase (MEK)/extracellular signal-related kinase (ERK) signaling pathway, which is often dysregulated in human cancers and plays a key role in tumor cell proliferation and survival. The Raf mutation B-Raf V600E, where the valine at residue 600 is substituted for glutamic acid, is frequently overexpressed in a variety of human tumors and results in the constitutive activation of the Raf/MEK/ERK signaling pathway. Check for active clinical trials using this agent. (NCI Thesaurus)
