    HCV NS5B polymerase, an essential and virus-specific enzyme, is an important target for drug discovery. Using structure-based design, we optimized a 1,5-benzodiazepine NS5B polymerase inhibitor chemotype into a new sulfone-containing scaffold. The design yielded potent inhibitor (S)-4c (K(D) = 0.79 nM), which has approximately 20-fold greater affinity for NS5B than its carbonyl analogue (R)-2c.
