  Improved P2 phenylglycine-based hepatitis C virus NS3 protease inhibitors with alkenylic prime-side substituents

  摘要：

  Phenylglycine has proved to be a useful P2 residue in HCV NS3 protease inhibitors. A novel pi-pi-interaction between the phenylglycine and the catalytic H57 residue of the protease is postulated. We hypothesized that the introduction of a vinyl on the phenylglycine might strengthen this pi-pi-interaction. Thus, herein is presented the synthesis and inhibitory potency of a series of acyclic vinylated phenylglycine-based HCV NS3 protease inhibitors. Surprisingly, inhibitors based on both D-and L-phenylglycine were found to be effective inhibitors, with a slight preference for the D-epimers. Furthermore, prime-side alkenylic extension of the C-terminal acylsulfonamide group gave significantly improved inhibitors with potencies in the nanomolar range (similar to 35 nM), potencies which were retained on mutant variants of the protease.
