    Hepatitis C virus (HCV) infection is treated with a combination of peginterferon alfa-2a/b and ribavirin. To address the limitations of this therapy, numerous small molecule agents are in development, which act by directly affecting key steps in the viral life-cycle. Herein we describe our discovery of quinolone derivatives, novel small-molecules that inhibit NS5b polymerase, a key enzyme of the viral life-cycle. A crystal structure of a quinoline analog bound to NS5B reveals that this class of compounds binds to allosteric site-II (non-nucleoside inhibitor-site 2, NNI-2) of this protein.
