生物活性

製品説明 ダノプレビルは、C型肝炎ウイルス (HCV) のNS3/4A プロテアーゼのペプチドミメティック阻害剤であり、IC50は0.2-3.5 nMです。HCVジェノタイプ1A/1B/4/5/6に対する阻害効果は、2B/3Aより約10倍高くなっています。第2相。
in vitro

Danoprevir (0.29 nM) inhibits the reference genotype 1 NS3/4A protease half-maximally, but a high dose of this compound (10 μM) shows no appreciably inhibition in a panel of 79 proteases, ion channels, transporters, and cell surface receptors. It remains bound to and inhibits NS3/4A for more than 5 hours after its initial association. This chemical (45 nM) eliminates a patient-derived HCV genotype 1b replicon from hepatocyte-derived Huh7 cells with an EC50 of 1.8 nM. In HCV subgenomic replicon cell lines containing the individual mutations, V36M, R109K, and V170A substitutions confer little or no resistance to it, but the R155K substitution confers a high level (62-fold increase) of resistance to this compound. In Huh7.5 cells transfected with chimeric recombinant virus, it shows antiviral inhibition effects against HCV genotypes 1, 4 and 6 with IC50 of 2-3 nM, which are >100-fold lower than genotypes 2/3/5 (280-750 nM).

in vivo

Danoprevir (30 mg/kg) administered to rats or monkeys shows that its concentrations in liver 12 hours after dosing exceed the concentration of this compound required to eliminate replicon RNA from cells.

特徴 A peptidomimetic inhibitor of the NS3/4A protease of hepatitis C virus (HCV).

プロトコル(参考用のみ)

キナーゼアッセイ Continuous fluorescent resonance energy transfer (FRET) assay
The assay buffer contains 25 μM NS4A peptide, 50 mM Tris-HCl, pH 7.5, 15% vol/vol, 10 mM dithiothreitol, and 0.5 μM QXL520-labeled FRET substrate {Ac-DE-Dap(QXL520)-EE-Abu-ψ-[COO]-AS-Cys(5-FAMsp)-NH2}. K2040 enzyme (50 pM) is added to initiate the reaction. Reactions are set up in black 96-well plates, and fluorescence data is collected. Control reactions lacking inhibitors and enzyme are included. Initial rates are calculated from the linear phase of the reaction (up to 1 hour) and are used to obtain IC50. Recovery of activity from preformed this compound-NS3/4A complex is assessed by preincubating 10 nM NS3/4A with a two-fold excess of this chemical in 1× assay buffer for 15 min, followed by a rapid 200-fold dilution of the preformed complex into assay buffer containing substrate. A control reaction with the same final conditions without preincubation of NS3/4A and this compound is initiated by the addition of enzyme to an otherwise-complete reaction mixture. Additional control reactions lack either this chemical or NS3. The progress of the reactions is followed over 5 hours.

実験の流れ

Serially diluted Danoprevir is added to Huh7 cells harboring the K2040 replicon 1 day after cell plating. For antiviral assays, after a 48-hour incubation, intracellular RNA is extracted, and the level of HCV replicon RNA is quantified by reverse transcription (RT)-PCR assay with the primers (5'-CACTCCCCTGTGAGGAACTACTG-3' and 5'-AGGCTGCACGACACTCATACT-3') and a probe (5'-6-FAM-CTTCACGCAGAAAGCGTCTAGCCATGG-MGBNFQ-3' using an ABI Prism 7900 sequence detection system. Here, FAM is 6-carboxyfluorescin and MGBNFQ is a molecular-groove binding non-fluorescence quencher specific to the HCV 5' untranslated region. Single-tube reactions are performed using the TaqMan Gold RT-PCR kit. Triplicate reactions for the RNA standards and samples are performed in 50 μL with 5 μL intracellular RNA (50 ng). RT is carried out at 48 °C for 30 min followed by 10 min at 95 °C. The PCR is run as follows: 15 seconds at 95 °C and 1 min at 60 °C for 40 cycles. Each RNA concentration is determined in triplicate. The absolute concentration of replicon RNA is calculated based on its signal relative to that of a standard curve generated by known concentrations of an in vitro-transcribed RNA corresponding to a genotype 1b 5' untranslated region. Replicon levels in the presence of this compound are fitted to a four-parameter logistic function to obtain EC50.
