HCV is responsible for about 200 million infections worldwide. The current therapy against HCV has numerous adverse effects, and is too costly for developing countries. In the present study, we assessed the efficacy of fluoroquinolone group of drugs against HCV helicase enzyme NS3, using in vitro and in silico approaches. For in vitro analysis, purified NS3 protein was used in helicase assays to assess the inhibitory effect of fluoroquinolones. Drugs that showed strong inhibition of NS3 were docked onto the NS3 protein using computer simulation. In vitro experimental analysis showed that several fluoroquinolones strongly inhibited the helicase activity of NS3. Docking analysis established that each of these drugs interacted strongly with different amino acids in the active site of NS3.This study will provide the basis for designing new fluoroquinolones derivatives that have the combined properties of pre-existing drugs, and hence a higher potency against HCV.
