Última Docking and QSAR Studies of Camptothecin Derivatives as Inhibitor of DNA Topoisomerase-I Nature Precedings Dharmendra K. Yadav; Feroz Khan; Santosh K. Srivastava. Camptothecin (CPT) is a cytotoxic quinoline alkaloid which inhibits the DNA enzyme Topoisomerase-I (Topo-I) and has shown remarkable anticancer activity in preliminary clinical trials. The major limitation is its low solubility and high adverse reaction. In the studied work, we performed molecular docking of CPT derivatives against Topo-I and developed the quantitative structure activity relationship (QSAR) model for anticancer activity screening. For QSAR, we used CPT and other anticancer drugs with its IC50 values. We used a total of forty seven anticancer drugs as training set and eight compounds as test set and thirty derivatives of CPT as query set. Total of fifty two chemical descriptors were used for the quantitative data calculation. Only four... Tipo: Poster Palavras-chave: Cancer; Chemistry; Pharmacology; Bioinformatics; Plant Biology.
