    • 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 religation, causing the accumulation of topoisomerase I-mediated single-strand DNA breaks in the DNA, and producing irreversible double-strand DNA breaks that lead to cell death.  Garcia-Carbonero, R. and Supko, J.G.  "Current perspectives on the clinical experience, pharmacology, and continued development of the camptothecins."  Clin. Cancer Res. 8:  641-661 (2002).
    • Both irinotecan and topotecan have activity in vivo against L1210 and P388 leukemia, mouse colon adenocarcinomas 38 and 51, Lewis lung carcinoma, mouse breast adenocarcinoma 16/C, and human tumor xenografts of B16 melanoma and HT-29 colon adenocarcinoma.  Rothenberg, M.L. "Topoisomerase I inhibitors: Review and update."  Ann. Oncol. 8:  837-855 (1997).
    • In the human tumor stem cell assay, irinotecan has activity in vitro against colorectal, non-small cell lung, ovarian, breast, mesothelioma, pancreas, sarcoma, and cervical cancers at low drug concentrations.  Shimada, Y., et al.  "Activity of CPT-11 (irinotecan hydrochloride), a topoisomerase I inhibitor, against human tumour colony-forming units."  Anticancer Drugs 5:  202-206 (1994).
    • Irinotecan is used to treat patients with colorectal cancer.  Fuchs, C., et al.  "Irinotecan in the treatment of colorectal cancer."  Cancer Treat. Rev. 32:  491-503 (2006).
    • Irinotecan is activated by hydrolysis to its active metabolite SN-38.  Kaneda, N., et al.  "Metabolism and pharmacokinetics of the camptothecin analogue CPT-11 in the mouse."  Cancer Res. 50:  1715-1720 (1990).  Kawato Y., et al.  "Intracellular roles of SN-38, a metabolite of the camptothecin derivative CPT-11, in the antitumor effect of CPT-11."  Cancer Res. 51:  4187-4191 (1991).
    • SN-38 is inactivated by the enzyme UGT1A1 by glucuronidation.  Iyer, L., et al.  "Genetic predisposition to the metabolism of irinotecan (CPT-11).  Role of uridine diphosphate glucuronosyltransferase isoform 1A1 in the glucuronidation of its active metabolite (SN-38) in human liver microsomes."  J. Clin. Invest. 101:  847-854 (1998).
    • Irinotecan is the active ingredient in the drug sold under the trade name Camptosar® in USA and Campto® in Japan.  This drug has been approved in at least one country for use in patients with metastatic colorectal cancer.  NOTE:  The irinotecan sold by LC Laboratories is NOT Camptosar® or Campto®, and is NOT for human use.
