Product Description

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.

How Topotecan Hydrochloride Works

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.
