QSAR and Molecular Modeling Studies on a Series of Indole-based Pyridone Analogues as HCV NS5B Polymerase Inhibitors

Quantitative structure-activity relationship (QSAR) and molecular modeling studies have been performed on a series of indole-based pyridone analogues as hepatitis C virus (HCV) NS5B polymerase inhibitors. A multiple linear regression (MLR) analysis has shown that the presence of hydrogen- bond donors in the molecule plays a negative role, but the substituents present on the indole ring sterically favor the activity of indole-based pyridine analogues. Using the MLR analysis model, some new analogues of indole-based pyridone with better potency have been predicted. Docking study has been performed on all the predicted compounds to study their binding modes with the receptor.
