Biological Activity

Asunaprevir (BMS-650032) is a potent hepatitis C virus (HCV) NS3 protease inhibitor for the treatment of hepatitis C virus infection. Asunaprevir competitively binds to the NS3/4A protease complex, with K(i) values of 0.4 and 0.24 nM against recombinant enzymes representing genotypes 1a (H77) and 1b (J4L6S), respectively. In cell culture, asunaprevir (BMS-650032) inhibited replication of HCV replicons representing genotypes 1 and 4, with 50% effective concentrations (EC(50)s) ranging from 1 to 4 nM, and had weaker activity against genotypes 2 and 3 (EC(50), 67 to 1,162 nM). Asunaprevir at doses of 200 to 600 mg resulted in rapid HCV RNA decreases from the baseline; maximal mean changes in HCV RNA over time were 2.7 and 3.5 log(10) IU/ml in the SAD and MAD studies, respectively. Plasma and tissue exposures in vivo in several animal species indicated that asunaprevir displayed a hepatotropic disposition (liver-to-plasma ratios ranging from 40- to 359-fold across species). Asunaprevir (BMS-650032) is currently in phase III clinical trials.

Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
