生物活性
Tivantinib (ARQ 197)是第一个非ATP竞争性的c-Met抑制剂，Ki为0.355 μM，对Ron几乎没有作用活性，对EGFR， InsR， PDGFRα和FGFR1/4没有抑制作用。Tivantinib (ARQ 197) 抑制HGF/c-met诱导的细胞反应。Tivantinib (ARQ 197) 具有抗肿瘤活性，抑制A549, DBTRG和NCI-H441细胞增殖，IC50分别为0.38, 0.45, 0.29 μM。用ARQ-197处理，导致MAPK信号级联放大磷酸化降低，且阻断入侵和迁移。

| 方法 | Cell proliferation assay
Cells were seeded in 96-well plates overnight in a medium with 10% FBS. Each cell line was optimized for seeding cell number to ensure a similar degree of confluence at the end of the experiment in nontreated (control) wells. The next day, cells were treated with different concentrations of ARQ 197 for 24 hours at 37°C. After ARQ 197 treatment, the drug-containing medium was removed, and cells were washed twice with PBS and incubated in a drug-free medium for an additional 48 hours. Cells were then incubated and stained for 4 hours with the MTS reagent (final concentration of 0.5 mg/mL; Promega) per well and were lysed. The results were quantitated by spectrophotometry at λ = 450 nm. |

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。
