Webcamptothecin ( uncountable ) ( medicine) An alkaloid, derived from the tree Camptotheca acuminata, that inhibits DNA topomerase and is used as an anticancer drug. Web(S)-(+)-Camptothecin binds irreversibly to the DNA-topoisomerase I complex, inhibiting the reassociation of DNA after cleavage by topoisomerase I and traps the enzyme in a covalent linkage with DNA. The enzyme complex is ubiquinated and destroyed by the 26S proteasome, thus depleting cellular topoisomerase I. Blocks the cell cycle in S-phase at ...
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.
