细胞实验 |
---|
细胞系 | NCI-H1975 and HCC827 cell lines |
方法 | Cell viability assays. Cells were grown in 96-well plates based on optimal growth rates determined empirically for each line. Twenty-four hours after plating, cells were treated with the indicated compounds or controls for 72 hours. AlamarBlue (Invitrogen) was added (10% v/v) to the cells, and the plates were incubated for 3 hours and, then, subjected to fluorescence detection. For the comparative viability/ apoptosis assay, NCI-H1975 cells were treated with escalating concentrations of ganetespib for the indicated time periods and subjected to viability analysis via CellTiter Fluor (Promega) and apoptosis via Caspase Glo 3/7 (Promega). |

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。
