Camptothecin (CPT) is a topoisomerase inhibitor. It was discovered in 1966 by M. E. Wall and M. C. Wani in systematic screening of natural products for anticancer drugs. It was isolated from the bark and stem of Camptotheca acuminata (Camptotheca, Happy tree), a tree native to China used in traditional Chinese medicine. It has been used clinically more recently in China for the tr… WebCamptothecin, an alkaloid isolated from the Chinese tree Camptotheca acuminate, is a potent cytotoxic agent, acting by the inhibition of DNA topoisomerase I [107]. Numerous derivatives of camptothecin have been synthesized in order to improve its pharmacological profile for effective anti‐tumour drugs.
