Topotecan Hydrochloride is a semi-synthetic camptothecin derivative used as an anticancer agent. It inhibits DNA topoisomerase I, leading to DNA damage and apoptosis in rapidly dividing tumor cells.
Topotecan selectively inhibits topoisomerase I by stabilizing the cleavable complex between the enzyme and DNA. This prevents DNA religation during replication, resulting in single-strand DNA breaks that trigger cell death, particularly in proliferating cancer cells.
