Irinotecan inhibits the action of topoisomerase I. Irinotecan prevents religation of the DNA strand by binding to topoisomerase I-DNA complex. The formation of this ternary complex interferes with the moving replication fork, which induces replication arrest and lethal double-stranded breaks in DNA.

It is converted via hydrolysis of the carbamate linkage to its active metabolite, SN-38, which is ~1000 times more active. It has a role as an EC 5.99.1.2 (DNA topoisomerase) inhibitor, an antineoplastic agent, an apoptosis inducer and a prodrug. It contains an irinotecan (1+).
Why is irinotecan a S-phase specific agent?
Because ongoing DNA synthesis is necessary for irinotecan to exert its cytotoxic effects, it is classified as an S-phase-specific agent. Irinotecan hydrochloride (anhydrous) is a hydrochloride obtained by combining irinotecan with one molar equivalent of hydrochloric acid.
