细胞系 | A431, SKBR3 and SW620 cells line |
方法 | Cell Proliferation Assay. Three human carcinoma cell lines, A431 (epidermoid carcinoma), SKBR3 (breast carcinoma), and SW620 (colon carcinoma), were used for the cell proliferation assays. All cell lines were obtained from the American Type Culture Collection. Cells were maintained in RPMI-1640 medium supplemented with 5% fetal bovine serum. Cells were plated in 96-well plates at the densities of 5.0 × 104/mL. On the next day, compounds were dosed at 0.5, 5, 50, 500, and 5000 ng/mL concentrations and the cells were cultured for 2 days. At the end of incubation, cell survival was determined by the sulforhodamine B assay as previously described.25 The IC50 values were obtained from the growth curves. |

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。
