Asunaprevir is an NS3 protease inhibitor used to treat hepatitis C genotype 1b.
Asunaprevir is a highly active HCV NS3 protease inhibitor. The genome of HCV has a positive polarity which allows it to be translated into a protein in the host cell without further transformation steps. However, the resultant protein needs to be divided by the enzyme NS3 protease into single proteins in order to be able to exert its enzymatic activity or structural role. Therefore, due to NS3 vital importance for viral replication, the inhibiting action of asunaprevir causes a robust antiviral activity.
Asunaprevir is indicated in combination with other agents for the treatment of chronic hepatitis C in adult patients with hepatitis C virus genotypes 1 or 4 and compensated liver cirrhosis. Hepatitis C is a liver disease caused by the hepatitis C virus. The chronic state of this condition accounts for 60-80% of the cases from which the risk of cirrhosis of the liver within 20 years is of around 15-30%. The genotype 1 is the most common type of hepatitis C in the United States and the most difficult to treat.
