Description and Uses
Topotecan was launched in the US for the second-line treatment of ovarian cancer. It can be prepared in four steps from camptothecin and is a water soluble derivative of the natural product with decreased toxicity. Unlike its chemical relative irinotecan, topotecacan in not a prodrug and does not require bioactivation. It is an inhibitor of topoisomerase I. Specifically, it inhibits the release of topoisomerase I from DNA, where it relaxes supercoiled DNA, giving rise to single-strand breaks. When the replication fork reaches this complex, double-stand breaks can occur. This signals apoptosis and eventually gives rise to cell death. Evidence indicates hycamtin is safe for people with impaired hepatic function.
antineoplastic;DNA topoisomerase type 1 inhibitor
