生物活性
SGX-523是一种选择性的Met抑制剂，IC50为4 nM，对BRAFV599E， c-Raf， Abl和p38α无抑制活性。SGX-523属于c-Met/肝细胞生长因子受体 (HGFR) 酪氨酸激酶抑制剂，使MET处于失活状态而不能接近其他蛋白激酶。SGX523有效抑制纯化的MET催化区，而不是紧密相关的受体酪氨酸激酶RON。SGX523是ATP竞争性抑制剂，作用于低活性和非磷酸化的MET时亲和力更高（MET-KD(0P), Ki= 2.7 nM）。

| 方法 | Scatter and Migration Assays
To measure the effect of SGX523 on HGF-induced cell scatter, MDCK cells were plated at 1 × 103per well in a 24-well plate and incubated at 37°C in 5% CO2 for 1 week in MEM and 10% fetal bovine serum. HGF (90 ng/mL) and various concentrations of SGX523 were added, and the cells were incubated for 18 h (37°C, 5% CO2 humidified incubator) and visualized. To investigate cell migration, A549 cells were plated in 12-well plates (6 × 104per well) and incubated to confluence. A channel was introduced into the monolayers by scratching with a pipette tip. Various dilutions of compound were added in starve medium in the presence and absence of HGF (90 ng/mL). Twenty-four hours later, wells were checked for cell migration. Cells were stained and visualized as described. |

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。
