细胞系 | Jurkat cells |
方法 | Cell lines culture and survival assays. Cell lines were cultured in RPMI-1640 medium, 10% fetal bovine serum (FBS), and penicillin/streptomycin at 37°C and 5% CO2. Medium was changed 12–24 h before all experiments. To measure IC50 values, cells (2–6 × 104) were incubated for 96 h with increasing concentrations of AS605240, prednisolone, L-asparaginase, MTX or DNR. To measure Combination Index (CI) values between AS605240 and the other drugs, 2-fold ratios of the calculated IC50 values (0.25×, 0.5×, 1×, 2× or 4×) of each drug were used either in combination or as single drugs. Cells were treated for a total of 96 h. When drug scheduling was applied, one of the drugs was added 48 h after the start of the experiment. Cell viability was measured by the MTT assay. IC50 and CI values were calculated with the GraphPad Prism 5 (GraphPad Software, La Jolla, CA, USA) and Calcusyn (Biosoft, Cambridge, UK) [65] softwares, respectively. |

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。
