细胞系 | MCF-7 cells |
方法 | In Vitro Proliferation Assay Cells were seeded onto 96- well plates at the densities of 3000 cells/well. After 24 h of pre-cultivation, appropriate concentrations of the samples were added and the cells were cultured for 2 d. The relative growth ratio was determined by WST-1 assay using a cell counting kit (Dojindo Laboratories, Kumamoto, Japan) according to the manufacturer’s instructions. The IC50 value was determined from the dose response curve. At least three independent experiments were performed. The proliferation assay that tested the effects of DMS was performed using identical methods. Compounds with or without DMS were added to the wells and the plates were incubated for 78 h at 37 °C in a humidified atmosphere containing 5% CO2 before
the WST-1 assay was conducted. |

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。
