Irinotecan is 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...

Description: 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. Target: Topoisomerase, Autophagy....
