Topotecan denosine 20-lyase and 17α-hydroxylase with IC50Topocecan is a semisynthetic derivative of camptothecin with antineoplastic activity. During the S phase of the cell cycle, topotecan selectively stabilizes topoisomerase I DNA covalent complexes, inhibiting religation of topoisomerase I mediated single strand DNA breaks and producing potentially lethal double strand DNA breaks when complexes are encountered by the DNA replication machinery. Camptothecin is a cytotoxic quinoline based alkaloid
