- Abstract
Quantitative structure-activity relationship studies were carried out on some novel HCV NS5B polymerase inhibitors comprising 1,1-dioxoisothiazoles and benzo [b] thiophene-1,1-dioxides using genetic function algorithm (GFA) and molecular field analysis (MFA) techniques. The statistically significant 2D/3D-QSAR models (r2 > 0.975) showed the indispensable structural requirements to improve the activity of this class. High r2CV values of 0.961 and 0.945 and r2pred values of 0.856 and 0.992 respectively for 2D/3D-QSAR models indicated the significant predictive ability of derived models. The validation of the models was done by full cross validation tests and external test set prediction. The results obtained can be exploited for modifications of the anti-HCV NS5B polymerase activity of this class of analogs.
