生物活性
ABT-333 is a nonnucleoside NS5B polymerase inhibitor for the treatment of HCV infection. An interferon-free combination of the protease inhibitor ABT-450 with ritonavir (ABT-450/r), the nonnucleoside polymerase inhibitor ABT-333, and ribavirin showed efficacy against the hepatitis C virus (HCV) in a pilot study involving patients with HCV genotype 1 infection. ABT-333 is currently under clinical trials for the treatment of Hepatitis C.

细胞系 | HCV replicon cells |
方法 | MTT analysis Both replicon-containing cell lines were maintained in Dulbecco’s modified Eagle’s medium (DMEM) containing 100 IU/ml penicillin, 100 g/ml streptomycin, and 200 g/ml G418 (all from Invitrogen, Carlsbad, CA) with 10% (vol/vol) fetal bovine serum (FBS).TheinhibitoryeffectsofdasabuvironHCVRNAreplication were determined in DMEM containing 5% FBS, with or without 40% human plasma (Bioreclamation, Westbury, NY), by measuring the activity of the luciferase reporter gene. The cells were incubated for 3 days in the presence of dasabuvir and subsequently were lysed and processed according to the manufacturer’s instructions (Promega, Madison, WI). The luciferase activity in the cells was measured using a Victor II luminometer (Perkin-Elmer, Waltham, MA); 50% effective concentration (EC50) values were calculated using nonlinear regression curve fitting to a 4-parameter logistic equation with GraphPad Prism 4 software. EC50s and standard deviations (SDs) were calculated from at least 3 experiments conducted in duplicate. The cytotoxicity of dasabuvir was determined with the colorimetric assay using MTT. |
浓度 | Dasabuvir inhibited 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. |

不同实验动物依据体表面积的等效剂量转换表(数据来源于FDA指南)
| 小鼠 | 大鼠 | 兔 | 豚鼠 | 仓鼠 | 狗 |
重量 (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
体表面积 (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
Km系数 | 3 | 6 | 12 | 8 | 5 | 20 |
动物 A (mg/kg) = 动物 B (mg/kg) × | 动物 B的Km系数 |
动物 A的Km系数 |
例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
