Description

Camptothecin-20(S)-O-propionate (CZ48) is a prodrug of camptothecin, an alkaloid isolated from the Chinese tree Camptotheca acuminata, with potential antineoplastic activity. Upon entry into cells, camptothecin-20(S)-O-propionate is hydrolyzed by esterases into the active form camptothecin. 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. CZ48 is being investigated in clinical trials for the treatment of advanced solid tumors and lymphomas.
