(S)-10-Hydroxycamptothecin, with the CAS number 19685-09-7, is a naturally occurring alkaloid derived from the seeds or root bark of the Camptotheca acuminata tree. This compound has gained significant attention due to its potent inhibitory activity against topoisomerase I, an enzyme crucial for DNA replication and repair. (S)-10-Hydroxycamptothecin exists as a yellow to orange crystalline powder and is primarily used in the development of anticancer drugs. Its mechanism of action involves stabilizing the topoisomerase I-DNA covalent complex, leading to DNA damage and ultimately cell death. This compound holds promise for the treatment of various cancers, making it a valuable addition to the field of oncology.
