Camptothecin Definition
An alkaloid isolated from the Chinese tree Camptotheca acuminata, with antineoplastic activity. During the S phase of the cell cycle, camptothecin selectively stabilizes topoisomerase I-DNA covalent complexes, thereby inhibiting religation of topoisomerase I-mediated single-strand DNA breaks and producing potentially lethal double-strand DNA breaks when encountered by the DNA replication machinery. (NCI)
