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 (CPT) is known to be a potent topoisomerase inhibitor (Pommier, 2006) and has been a target for conjugation to dendronized systems. Zhou et al. designed a dendrimer where a single camptothecin molecule is the core, to which a G5-poly- l -lysine dendrimer was constructed (characterized by MALDI-TOF MS, NMR, HPLC, and UV/Vis) … WebIn terms of discovery, camptothecin (2) was originally isolated by Wall et al. 393 in pioneering studies in 1966 as a novel alkaloidal leukemia and tumor inhibitor. Its mode of action is that of binding to topoisomerase 1 and DNA complex, which thus prevents DNA re-ligation resulting in apoptosis via DNA damage. 414,415
