Current treatment for hepatitis C is barely satisfactory, there is an urgent need to develop novel agents for combating hepatitis C virus infection. This study discovered a new class of thieno[2,3-b]pyridine derivatives as HCV inhibitors. First, a hit compound characterized by a thienopyridine core was identified in a cell-based screening of our privileged small molecule library. And then, structure activity relationship study of the hit compound led to the discovery of several potent compounds without obvious cytotoxicity in vitro (12c, EC50 = 3.3 μM, SI >30.3, 12b, EC50 = 3.5 μM, SI >28.6, 10l, EC50 = 3.9 μM, SI >25.6, 12o, EC 50 = 4.5 μM, SI >22.2, respectively). Although the mechanism of them had not been clearly elucidated, our preliminary optimization of this class of compounds had provided us a start point to develop new anti-HCV agents.

A simple and convenient preparative method for the synthesis of 3-cyano-4-difluoro- and -trifluoromethylpyridine-2(1H)-thiones was developed. During studies of synthetic potential of these compounds, approaches to the synthesis of a number of annulated heterocyclic systems were suggested.
