Camptothecin
Topoisomerase I inhibitor
Product Specifications
Background
Camptothecin is a cytotoxic quinoline alkaloid which inhibits the DNA enzyme topoisomerase I. It binds to the topo I and DNA complex, resulting in a tertiary comlex which stabilizes it. This prevents re-ligation and therefore causes DNA damage which results in apoptosis (1-3). It has showed remarkable anti-cancer activity in clinical trials.
