[EN] MACROCYCLIC SERINE PROTEASE INHIBITORS USEFUL AGAINST VIRAL INFECTIONS, PARTICULARLY HCV [FR] INHIBITEURS MACROCYCLIQUES DE LA SÉRINE PROTÉASE MACROCYCLIQUE UTILES CONTRE LES INFECTIONS VIRALES, EN PARTICULIER LE VIRUS DE L’HÉPATITE C
Provided herein are macrocyclic serine protease inhibitor compounds, for example, of Formula Ia or Ib, pharmaceutical compositions comprising the compounds, and processes of preparation thereof. Also provided are methods of their use for the treatment of an HCV infection in a host in need thereof.
Exploration of the P2 region by mimicking the proline motif found in BILN2061 resulted in the discovery of two series of potent HCV NS3/4A protease inhibitors. X-ray crystal structure of the ligand in contact with the NS3/4A protein and modulation of the quinoline heterocyclic region by structure based design and modeling allowed for the optimization of enzyme potency and cellular activity. This research led to the selection of clinical candidate IDX320 having good genotype coverage and pharmacokinetic properties in various species. (C) 2015 Elsevier Ltd. All rights reserved.
