Thermo Scientific™ Camptothecin, (HPLC) >90%

Thermo Scientific™ Camptothecin is a cytotoxic plant alkaloid and a potent DNA topoisomerase I inhibitor with well-established anticancer properties.

This compound interferes with the re-ligation step of the topoisomerase I-mediated DNA cleavage-rejoining process, leading to DNA strand breaks, cell cycle arrest, and apoptosis in rapidly dividing cells.

Originally isolated from Camptotheca acuminata, camptothecin is used in oncology research and serves as the parent compound for clinically approved chemotherapeutic analogues such as irinotecan and topotecan.

Key Features

• Cytotoxic Antitumor Agent: Induces apoptosis via DNA damage through topoisomerase I inhibition.
