About Antineoplastic - Topoisomerase I Inhibitors.

Antineoplastic topoisomerase I inhibitors are a class of cytotoxic anticancer agents derived primarily from the natural alkaloid camptothecin.

They exert their therapeutic effect by binding to and stabilizing the transient topoisomerase I–DNA cleavage complex, preventing DNA religation and inducing lethal double-strand DNA breaks during replication, which ultimately triggers tumor cell apoptosis.

Clinically, members of this class—such as irinotecan and topotecan, as well as novel topoisomerase I inhibitor-based antibody-drug conjugates—are predominantly indicated for the management of solid tumors, including advanced colorectal, pancreatic, ovarian, cervical, and small cell lung cancers.
