Boceprevir 是一种口服有效的选择性HCV NS3 蛋白酶抑制剂。在酶试验中的 Ki 为 14 nM，在基于细胞的复制子试验中 EC90 为 350 nM。它也是 SARS-CoV-2 3CLpro 抑制剂。

Boceprevir is a novel, potent, highly selective, orally bioavailable HCV NS3 protease inhibitor with Ki of 14 nM in both enzyme assay and EC90 of 350 nM in cell-based replicon assay.

In the HCV NS3 protease continuous assay, Boceprevir (SCH 503034) has a potency of 14 nM (Ki) average over a large number of runs. In the 72-h bicistronic subgenomic cell-based replicon assay in HuH-7 cells, the EC50 and EC90 values are determined to be 0.20 μM and 0.35 μM, respectively. Boceprevir is also found to be a very weak inhibitor of HNE (Ki=26 μM) representing a selectivity of 2200.

Boceprevir is an HCV Protease Inhibitor for the Treatment of Hepatitis C Virus Infection. The pharmacokinetic profile of Boceprevir is evaluated in several animal species. Boceprevir is moderately absorbed in rats (10 mg/kg), dogs (3 mg/kg), and monkeys (3 mg/kg) following oral administration. Absorption is relatively rapid in dogs but slower in mice (10 mg/kg), rats, and monkeys, as evidenced by mean absorption times (MAT) ranging from 0.5 to 1.4 h. The AUC is good in dogs and rats, moderate in mouse, and low in monkeys. The absolute oral bioavailability is modest in mouse, rats, and dogs (26-34%) but low in monkeys (4%)[1]. Boceprevir (100 mg/kg, orally) inhibit HCV NS3/4A protease activity in triple-transgenic mice.
