生物活性
TMC435350 (Simeprevir) is an oral HCV NS3/4A protease inhibitor. TMC435350 inhibited HCV replication in a cellular assay (subgenomic 1b replicon) with a half-maximal effective concentration (EC(50)) of 8 nM and a selectivity index of 5,875. In rats, TMC435350 was extensively distributed to the liver and intestinal tract (tissue/plasma area under the concentration-time curve ratios of >35), and the absolute bioavailability was 44% after a single oral administration. TMC435350 also displayed low in vitro clearance and high permeability, which were confirmed by in vivo pharmacokinetic studies. Data from phase I and II clinical trials of TMC-435350 (Simeprevir) have shown that TMC435350 is well tolerated as a once-daily oral therapy and provides potent antiviral activity in HCV genotype 1-infected subjects, with restoration of liver enzymes and no evidence of viral breakthrough.

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。
