title: Design and synthesis of potent, non-peptide inhibitors of HCV NS3 protease.
abstract: Starting from a hexapeptide boronic acid lead, 3-amino bicyclic pyrazinones as novel beta-sheet dipeptide mimetics have been designed and synthesized. Side-chain manipulation of this scaffold generated a series of potent, nonpeptidic inhibitors of HCV NS3 protease.
