cpt 11

Irinotecan Hydrochloride (CPT-11 hydrochloride) is the hydrochloride salt of a semisynthetic derivative of camptothecin. Irinotecan, a prodrug, is converted to a biologically active metabolite 7-ethyl-10-hydroxy-camptothecin (SN-38) by a carboxylesterase-converting enzyme. One thousand-fold more potent than its parent compound irinotecan, SN-38 inhibits topoisomerase I activity by stabilizing the cleavable complex between topoisomerase I and DNA, resulting in DNA breaks that inhibit DNA replication and trigger apoptotic cell death. Because ongoing DNA synthesis is necessary for irinotecan to exert its cytotoxic effects, it is classified as an S-phase-specific agent.

Irinotecan (CPT-11), a derivative of camptothecin, is an inhibitor of DNA topoisomerase I (Topo I). Irinotecan has antitumor activity by preventing DNA strand reattachment through binding to the Topo I complex, resulting in double-stranded DNA breaks and cell death.

Irinotecan hydrochloride trihydrate (CPT-11 HCl Trihydrate) keeps DNA from unwinding by inhibiting topoisomerase 1.

RPR132595A is an active CPT-11 metabolite, it is generated by cytochrome P-450 3A4 (CYP3A4).

CL2-MMT-SN38 is a derivative of SN-38, which is a potent anticancer agent and the active metabolite of Irinotecan (CPT-11), a Topoisomerase I inhibitor.

ZBH-1205 is a novel camptothecin derivative, revealing potent antitumor activities mainly through cell apoptosis pathway, being more effective than cpt-11 and sn38 at inhibiting topoismerase-1

RPR132595A (NPC) hydrochloride, an active metabolite of CPT-11, is produced via cytochrome P-450 3A4 (CYP3A4) metabolism and is ultimately eliminated via urinary excretion [1].

A011, a potent and selective ataxia-telangiectasia mutated (ATM) inhibitor, exhibits an IC50 of 1.0 nM and triggers apoptosis as well as G2/M phase cell cycle arrest when combined with CPT-11, displaying notable antitumor activity [1].

Irinotecan (Standard) is a reference standard for research and analysis in studies involving Irinotecan. Irinotecan (CPT-11), a derivative of camptothecin, is an inhibitor of DNA topoisomerase I (Topo I). Irinotecan has antitumor activity by preventing DNA strand reattachment through binding to the Topo I complex, resulting in double-stranded DNA breaks and cell death.
