产品描述 | Dasabuvir (ABT-333) is a non-nucleoside inhibitor of the hepatitis C virus (HCV) non-structural protein 5B (NS5B), an RNA-dependent RNA polymerase, with potential activity against HCV. Upon administration and after intracellular uptake, dasabuvir binds HCV NS5B polymerase and blocks viral RNA synthesis and replication. The HCV NS5B protein is essential for the replication of the HCV RNA genome. |

体外活性 | ABT-333 (Dasabuvir) is at least 7,000-fold selective for the inhibition of HCV genotype 1 polymerases over human/mammalian polymerases. ABT-333 (Dasabuvir) inhibits the polymerase enzymatic activity of genotype 1 laboratory strain enzymes (H77, BK, N, and Con1 strains), as well as enzymes produced from polymerase genes from HCV genotype 1-infected subjects, with IC50s between 2.2 and 10.7 nM. ABT-333 inhibits replication of HCV subgenomic replicons in cell culture assays, with EC50 values of 7.7 and 1.8 nM against genotype 1a (H77) and 1b (Con1), respectively. In the presence of 40% human plasma, there is a 12- to 13-fold decrease in inhibitory potency, yielding EC50s of 99 and 21 nM for HCV genotype 1a (H77) and 1b (Con1) replicons, respectively[1]. |
激酶实验 | The recombinant HCV polymerases used in this study contain the first 570 amino acids of the 591-amino acid native protein sequence, with a six-histidine tag at the N terminus to facilitate purification by affinity chromatography. Briefly, ABT-333 (Dasabuvir) is incubated with 5 to 50 nM polymerase for 15 min at room temperature, follow by the addition of nucleoside triphosphates (NTPs) and [3H]UTP for 3 h at 30°C. After termination of the reaction, the precipitated RNA is captured by filtration through a GF/B filter. The amount of incorporated [3H]UTP is measured by scintillation counting with a Wallac 1450 MicroBeta counter. The percent inhibition is calculated from the initial rates of inhibited reactions relative to that of the uninhibited control reaction. The mean 50% inhibitory concentration (IC50) and the standard error of the mean (SEM) are calculated via nonlinear regression[1]. |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
