Definitions

  • the present invention relates to a field of medicine, and compounds and compositions thereof for treating Hepatitis C virus (HCV) infection, and use of the compounds and the compositions thereof, and methods thereof.
  • the compounds disclosed herein can be used for inhibiting NS3/4A protease.
  • the present invention relates to compounds and pharmaceutical compositions thereof which can be used for inhibiting a function of NS3/4A protein coded by the hepatitis C virus (HCV) , and a method of inhibiting NS3/4A protein function.
  • HCV is a major human pathogen, infecting an estimated 170 million persons worldwide roughly five times the number infected by human immunodeficiency virus type 1. A substantial fraction of these HCV infected individuals develop serious progressive liver disease, including cirrhosis and hepatocellular carcinoma. Chronic HCV infection is thus a major worldwide cause of liver-related premature mortality.
  • HCV is a positive-stranded RNA virus. Based on a comparison of the deduced amino acid sequence and the extensive similarity in the 5’untranslated region, HCV has been classified as a separate genus in the Flaviviridae family. All members of the Flaviviridae family have enveloped virions that contain a positive stranded RNA genome encoding all known virus-specific proteins via translation of a single, uninterrupted, open reading frame (ORF) .
  • ORF open reading frame
  • HCV infected cells viral RNA is translated into a polyprotein that is cleaved into ten individual proteins. At the amino terminus are structural proteins, follows E1 and E2. Additionally, there are six non-structural proteins, NS2, NS3, NS4A, NS4B, NS5A and NS5B, which play a function role in the HCV lifecycle (see, for example, Lindenbach et al., Nature, 2005, 436, 933-938) .
  • HCV human immunodeficiency virus
  • the first one is believed to be a metalloprotease and cleaves at the NS2-NS3 junction; the second one is a serine protease within the N-terminal region of NS3 (also referred herein as NS3 protease) and mediates all the subsequent cleavages downstream of NS3, both in cis, at the NS3-NS4A cleavage site, and in trans, for the remaining NS4A-NS4B, NS4B-NS5A, NS5A-NS5B sites.
  • the NS4A protein appears to serve multiple functions, acting as a cofactor for the NS3 protease and possibly assisting in the membrane localization of NS3 and other viral replicase components.
  • NS5B (also referred to herein as HCV polymerase) is a RNA-dependent RNA polymerase that is involved in the replication of HCV.
  • the compounds disclosed herein are used for treating HCV-infection in a patient, and which inhibit HCV viral replication selectively.
