Danoprevir (ITMN-191) 是一种具有口服活性的NS3/4A蛋白酶抑制剂,IC50值为 0.29 nM。与其他 53 种蛋白酶 (IC50高于 10 μM) 相比,对 NS3/4A 具有高选择性。Danoprevir (ITMN-191) 抑制 HCV 基因型 1a, 1b, 4, 5, 6 (IC50s=0.2-0.4 nM) 和 2b, 3a (IC50s=1.6, 3.5 nM)。Danoprevir 也是SARS-CoV 3CLpro的抑制剂,IC50为 0.05 μM。
生物活性 | Danoprevir (ITMN-191) is an orally activeNS3/4A proteaseinhibitor for hepatitis C virus (HCV) with anIC50of 0.29 nM and is selective for NS3/4A over a panel of 53 proteases (IC50higher than 10 μM). Danoprevir (ITMN-191) inhibitsHCVgenotypes 1a, 1b, 4, 5, and 6 (IC50s=0.2-0.4 nM) as well as 2b and 3a (IC50s=1.6, 3.5 nM)[1][2]. Danoprevir is also aSARS-CoV3CLproinhibitor with anIC50of 0.05 μM[3]. |
IC50& Target | IC50: 0.29 nM (NS3/4A protease), 0.2-3.5 nM (HCV genotypes 1a, 1b, 2b, 3a, 4, 5, 6)[2] |
体外研究 (In Vitro) | In Huh7.5 cells transfected with chimeric recombinant virus, Danoprevir (ITMN-191) shows antiviral inhibition effects against HCV genotypes 1, 4 and 6 with IC50of 2-3 nM, which are >100-fold lower than genotypes 2/3/5 (280-750 nM)[1]. Danoprevir (ITMN-191) inhibits the reference genotype 1 NS3/4A protease half-maximally, but a high dose of Danoprevir (ITMN-191) (10 μM) shows no appreciably inhibition in a panel of 79 proteases, ion channels, transporters, and cell surface receptors. Danoprevir (ITMN-191) remains bound to and inhibits NS3/4A for more than 5 hours after its initial association. Danoprevir (ITMN-191) (45 nM) eliminates a patient-derived HCV genotype 1b replicon from hepatocyte-derived Huh7 cells with an EC50of 1.8 nM[2]. In HCV subgenomic replicon cell lines containing the individual mutations, V36M, R109K, and V170A substitutions confer little or no resistance to Danoprevir (ITMN-191), but the R155K substitution confers a high level (62-fold increase) of resistance to Danoprevir[3].

体内研究 (In Vivo) | Danoprevir (ITMN-191) (30 mg/kg, p.o.) administered to rats or monkeys shows that its concentrations in liver 12 hours after dosing exceed the Danoprevir concentration required to eliminate replicon RNA from cells[2].
