Paritaprevir
Based on 13 publication(s) in Google Scholar
Paritaprevir (ABT-450) is a potent, orally active and antiviral non-structural protein 3/4A (NS3/4A) protease inhibitor with EC50s of 1 and 0.21 nM against HCV 1a and 1b, respectively. Paritaprevir is also a SARS-CoV 3CLpro inhibitor with an IC50 of 1.31 μM. Paritaprevir is metabolized primarily by cytochrome P450 (CYP) 3A. The plasma concentration and half-life of Paritaprevir can be enhanced by Ritonavir (a CYP450 inhibitor).

Biological Activity
EC50: 1 nM (HCV 1a), 0.21 nM (HCV 1b)[1]
IC50: 1.31 μM (SARS-CoV 3CLpro)[3]
The acute toxicity of Paritaprevir is considered to be low. Single oral doses of ≤600 mg/kg in rats and ≤100 mg/kg in dogs produces no mortality and were well tolerated. However, since Paritaprevir is administered without ritonavir as a PK enhancer, the exposures are low, especially in male rats (rat 600 mg/kg, males: Cmax 1.82 μg/mL, AUC0-24 8.89 μg·h/mL; dog 100 mg/kg, mean: Cmax 61.3 μg/mL, AUC0-24 285 μg·h/mL).
