Recently, a series of N-acetamideindolecarboxylic acids were studied for their HCV NS5B polymerase inhibition activity. We report here a QSAR and docking study on them to investigate the physicochemical and structural properties of the molecules that govern their activity in order to rationalize the structural modification to have more potent drugs. A multiple regression analysis reveals a significant correlation of NS5B inhibition activity of compounds with their hydrophobicity, Kier’s first order valence molecular connectivity index of a substituent and an indicator parameter, suggesting that the hydrophobicity and a particular substituent of the compounds containing atoms with low valence and high saturation will be conducive to the activity. Also the binding of compounds to Site 1 concluded that conformations of HCV NS5B polymerase could be an important regulatory step in RNA synthesis and can be further exploited by designing non-nucleoside inhibitors.
