Camptothecin supplement

WebJun 13, 2024 · Camptothecin is an anticancer molecule which acts by targeting the human deoxyribonucleic acid topoisomerase I (Topo-I). It inhibits the enzyme by blocking the re-joining step of the cleavage reaction of Topo-I, which causes accumulation of a covalent reaction intermediate. WebCamptothecin is a potent anti-tumor drug that specifically targets DNA topoisomerase I by reversibly stabilizing a covalent enzyme-DNA intermediate (reviewed in Refs. 2 , 4 , 5 , 6 , 7 ). In the yeast Saccharomyces cerevisiae, DNA topoisomerase I has been shown to constitute the cellular target of the drug ( 8 , 9 , 10 , 11 , 12 , 13 , 14 ).
