Topotecan hydrochloride (trade name Hycamtin) is a chemotherapy agent that is a topoisomerase I inhibitor.

 It is often used in the treatment of ovarian and lung cancers, as well as other cancer types.

Topotecan intercalates between DNA. This intercalation disrupts the DNA duplication machinery when it finds a site in the DNA where topotecan is intercalated. This disruption prevents DNA replication, and ultimately leads to cell death.
