Product Overview
Asunaprevir is an orally efficacious inhibitor of NS3 protease with IC50 value of 1nM. Asunaprevir is an inhibitor of hepatitis C virus (HCV) NS3 protease. It can inhibit 6 major genotypes of HCV NS3/4A protease with IC50 values of 0.7nM, 0.3nM, 15nM, 78nM, 320nM, 1.6nM, 1.7nM and 0.9nM, respectively for genotype 1a, 1b, 2a, 2b, 3a, 4a, 5a and 6a, respectively. When using the purified recombinant full-length HCV NS3/4A protease complexes, asunaprevir shows the Ki values of 0.4nM and 0.2nM, respectively for genotype 1a and genotype 1b. The mechanism of the inhibition is that the acylsulfonamide of asunaprevir interacts with the catalytic site of NS3 protease in a noncovalent manner. Asunaprevir inhibits HCV RNA replication in different cell lines, including liver, T lymphocytes, lung, cervix, and embryonic kidney. It shows no obvious activity against other RNA viruses. The permeability of asunaprevir is similar to the compound with good absorption in humans. The tests of metabolism rate show that asunaprevir exhibits low to intermediate metabolic clearance. Plasma and tissue exposures in vivo indicate that asunaprevir displays a hepatotropic disposition.
