方法 | Cell proliferation assay The cell lines were added to the wells of 96-well plates containing 0.076 to 10,000 nmol/L CH5132799 and incubated at 37°C. After 4 days of incubation, Cell Counting Kit-8 solution (AbMole) was added and, after incubation for several more hours, absorbance at 450 nm was measured with Microplate-Reader iMark (Bio-Rad Laboratories). The antiproliferative activity was calculated by the formula (1 – T/C) × 100 (%), in which T and C represent absorbance at 450 nm of the cells treated with drugs (T) and that of untreated control cells (C). The IC50 values were calculated by using Microsoft Excel 2007. |

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 |

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。
