Description: Paritaprevir, also known as ABT-450 or Veruprevir, is an acylsulfonamide inhibitor of the NS3-4A serine protease manufactured by Abbott Laboratories that shows promising results as a treatment of hepatitis C. When given in combination with ritonavir and ribavirin for 12 weeks, the rate of sustained virologic response at 24 weeks after treatment has been estimated to be 95% for those with hepatitis C virus genotype 1. Resistance to treatment with paritaprevir is uncommon, because it targets the binding site, but has been seen to arise due to mutations at positions 155 and 168 in NS3.

More Info:

Biological target: Paritaprevir (ABT-450) is a potent non-structural protein 3/4A (NS3/4A) protease and SARS-CoV 3CLpro (IC50 of 1.31 μM.) inhibitor with EC50s of 1 and 0.21 nM against HCV 1a and 1b, respectively.
In vitro activity: ABT-450 inhibited genotype 1a-H77 and 1b-Con1 HCV subgenomic replicons in cell culture with EC50s of 1.0 and 0.21 nM, respectively. In the presence of 40% human plasma, the EC50s increased by 17- to 24-fold (Table 1). The CC50 of ABT-450 was >37 μM, resulting in an in vitro selectivity index of ≥37,000-fold. ABT-450 demonstrated activity across multiple HCV genotypes, with an EC50 of 5.3 nM against the genotype 2a JFH-1 subgenomic replicon and EC50s of 19, 0.09, and 0.69 nM against replicons containing NS3 protease from genotypes 3a, 4a, and 6a, respectively. As has been observed for other NS3/4A protease inhibitors such as simeprevir and asunaprevir, ABT-450 has reduced potency against genotype 3a, likely caused by the presence of the NS3 polymorphism D168Q, which is commonly found in this genotype.
