Camptothecin is a pyranoindolizinoquinoline that is pyrano[3,4:6,7]indolizino[1,2-b]quinoline which is substituted by oxo groups at positions 3 and 14, and by an ethyl group and a hydroxy group at position 4 (the S enantiomer). It has a role as an EC 5.99.1.2 (DNA topoisomerase) inhibitor, an antineoplastic agent, a genotoxin and a plant metabolite. It is a pyranoindolizinoquinoline, a tertiary alcohol, a delta-lactone and a quinoline alkaloid. Camptothecin is an alkaloid isolated from the stem wood of the Chinese tree, Camptotheca acuminata. This compound selectively inhibits the nuclear enzyme DNA topoisomerase, type I. Several semisynthetic analogs of camptothecin have demonstrated antitumor activity. Camptothecin is a natural product found in Archidendron lucidum, Merrilliodendron megacarpum, and other organisms with data available. Camptothecin is an alkaloid isolated from the Chinese tree Camptotheca acuminata, with antineoplastic activity. During the S phase of the cell cycle, 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. (NCI) An alkaloid isolated from the stem wood of the Chinese tree, Camptotheca acuminata. This compound selectively inhibits the nuclear enzyme DNA TOPOISOMERASES, TYPE I. Several semisynthetic analogs of camptothecin have demonstrated antitumor activity. A pyranoindolizinoquinoline that is pyrano[3,4:6,7]indolizino[1,2-b]quinoline which is substituted by oxo groups at positions 3 and 14, and by an ethyl group and a hydroxy group at position 4 (the S enantiomer). Camptothecin (CPT), a kind of alkaloid, is a DNA topoisomerase I (Topo I) inhibitor with an IC50 of 679 nM[1]. Camptothecin (CPT) exhibits powerful antineoplastic activity against colorectal, breast, lung and ovarian cancers, modulates hypoxia-inducible factor-1α (HIF-1α) activity by changing microRNAs (miRNA) expression patterns in human cancer cells[2][3].
