- liposomal SN-38
The liposomal formulation of SN-38 (7-ethyl-10-hydroxy-camptothecin), a biologically active metabolite of the prodrug irinotecan, with potential antineoplastic activity. SN-38 binds to and inhibits topoisomerase I by stabilizing the cleavable complex between topoisomerase I and DNA, resulting in DNA breaks, inhibition of DNA replication, and apoptosis. SN-38 has been reported to exhibit up to 1,000-fold more cytotoxic activity against various cancer cells in vitro than irinotecan. The liposomal formulation of SN-38 increases the solubility of SN-38, which is a relatively insoluble compound, and improves the pharmacodynamic profile as compared to SN-38 alone. Check for active clinical trials using this agent. (NCI Thesaurus)
