Irinotecan, a derivative of the alkaloid camptothecin (Cay-11694), functions as a prodrug that is converted by tissue carboxylesterase to 7-ethyl-10-hydroxycamptothecin, a potent inhibitor of DNA topoisomerase I. Its action is terminated by glucuronidation by UDP glucuronosyl transferase 1A1. Irinotecan demonstrates...

Inhibitor of the nuclear enzyme topoisomerase I, which is involved in cellular DNA replication and transcription. During replication Topoisomerase I mediates the relaxation of super coiled DNA, and it's inhibition results in breakage of the DNA chain and likely induce apoptosis. Irinotecan is therefore an attractive...

Irinotecan (CPT-11) is a topoisomerase I inhibitor. It is a semisynthetic analog of the natural alkaloid camptothecin and has an active metabolite SN-38 (7-Ethyl-10-hydroxycamptothecin). During the S phase of the cell cycle, camptothecins selectively bind to and stabilize topoisomerase I-DNA complexes, inhibiting...
