Biological Activity

Description Asunaprevir is an orally bioavailable inhibitor of the hepatitis C virus enzyme serine protease NS3 that is necessary for protein processing required for viral replication.
Targets
1b (J4L6S) [1] 1a (H77) [1] 6a (HK-6A) [1] 4a (ED43) [1] 5a (SA13) [1] View More
0.3 nM 0.7 nM 0.9 nM 1.6 nM 1.7 nM
In vitro Asunaprevir (ASV) competitively binds to the NS3/4A protease complex, with Ki values of 0.4 and 0.24 nM against recombinant enzymes representing genotypes 1a (H77) and 1b (J4L6S), respectively. Asunaprevir is high selective without any significant activity against the closely related GB virus-B NS3 protease and a panel of human serine or cysteine proteases. In cell culture, ASV inhibits replication of HCV replicons representing genotypes 1 and 4, with 50% effective concentrations (EC50s) ranging from 1 to 4 nM, and has weaker activity against genotypes 2 and 3 (EC50, 67-1162 nM). Selectivity is again demonstrated by the absence of activity (EC50, >12 μM) against a panel of other RNA viruses[1].
In vivo Plasma and tissue exposures in vivo in several animal species indicate that ASV displays a hepatotropic disposition (liver-to-plasma ratios ranging from 40- to 359-fold across species). Twenty-four hours postdose, liver exposures across all species tested are ≥110-fold above the inhibitor EC50s observed with HCV genotype-1 replicons[1].
