生物活性
Capmatinib (INCB28060)是一种新型, ATP竞争性的c-MET抑制剂,IC50为0.13 nM,Capmatinib 可抑制 c-MET 的磷酸化,以及 c-MET 通路下游效应蛋白如 ERK1/2、AKT、FAK、GAB1 和 STAT3/5。Capmatinib (INCB28060) 具有皮摩尔酶活效价,对 c-MET选择性比其它大部分人源激酶高出10000多倍。在肿瘤细胞里 INCB28060 可以抑制c-MET磷酸化以及c-MET介导的信号转导。Capmatinib (INCB28060) 抑制 c-MET依赖的细胞增殖和存活并且抑制anchorage非依赖性肿瘤细胞生长和细胞迁移。

方法 | Optimal cell density used in the viability assay was predetermined for individual cell lines. To determine compound potency, cells were seeded into 96-well microplates at the appropriate density in media containing 1% to 2% FBS and supplemented with serial dilutions of INCB28060 in a final volume of 100 μL per well. After 72-hour incubation, 24 μL of CellTiter 96 AQueous One Solution (Promega) was added to each well, and the plates were incubated for 2 hours in a 37°C incubator. The optical density was measured in the linear range using a microplate reader at 490 nm with wavelength correction at 650 nm. IC50 values were calculated using the GraphPad Prism Software. |

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。
