方法 | Cytotoxicity Assays. To study cytotoxicity in suspension cell lines, cells were plated in 96-well tissue culture plates at a density of 10,000 cells/well in RPMI 1640 supplemented with 10% FCS, 2 mm l-glutamine, 20 units/ml penicillin, and 20 μg/ml streptomycin. Drug was added to the culture medium to achieve final concentrations of 0.3 nm to 10 μm, with half-log increments, with and without VX-710 at a final concentration of 2.5 μM. The final volume of medium per well was 100 μl. Cells were incubated for 96 h at 37°C in a fully humidified atmosphere of 5% CO2 in air. Cell growth was assessed by the WST-1 colorimetric assay (Roche Diagnostics GmbH, Mannheim, Germany; Ref. 29 ), performed according to the manufacturer’s instructions. Briefly, 10 μl of WST-1 were added to each well, and culture plates were returned to the incubator for an additional 4 h. Subsequently, the absorbance at 450 nm (A450) and 600 nm (A600, background) was read for each well using a Microtek multiwell plate reader. Each drug exposure condition was assessed in quadruplicate. |

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。
