生物活性
TAS-115 (Pamufetinib) mesylate inhibited the kinase activity of both VEGFR2 and MET and their signal-dependent cell growth as strongly as other known VEGFR or MET inhibitors, with IC50 values of 30 and 32 nM for rVEGFR2 and rMET, respectively.
In vivo, TAS-115 (Pamufetinib) completely suppressed the progression of MET-inactivated tumor by blocking angiogenesis without toxicity when given every day for 6 weeks, even at a serum-saturating dose of TAS-115. TAS-115 (Pamufetinib) induced marked tumor shrinkage and prolonged survival in MET-amplified human cancer-bearing mice. TAS-115 is a unique VEGFR/MET-targeted inhibitor with improved antitumor efficacy and decreased toxicity.

| 方法 | Tumor cells (8000 cells/800 mL) with or without TAS-115 (1.0 μM) or erlotinib (0.3 μM) in the lower Transwell collagen–coated chambers are cocultured with MRC-5 (1000 cells/300 μL) cells in the upper chamber for 72 hours. The upper chamber is then removed. Cell viability is measured using the MTT assay. |

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 |

| 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。
