• PubMed Abstract: 
  

  A novel series of non-nucleoside thumb pocket 2 HCV NS5B polymerase inhibitors were derived from a fragment-based approach using information from X-ray crystallographic analysis of NS5B-inhibitor complexes and iterative rounds of parallel synthesis. Structure-based drug design strategies led to the discovery of potent sub-micromolar inhibitors 11a-c and 12a-c from a weak-binding fragment-like structure 1 as a starting point.
