方法 | XTT assay for cell proliferation. In brief, approximately 2*103cells were plated into microtiterplate wells in 100 ml RPMI-1640 growth media with indicated concentrations of inhibitor. The relative growth of cells was quantified at 24-h intervals using Cell Proliferation Kit II (XTT) as per manufacturer’s guidelines (Roche, Indianapolis, IN, USA). After incubation, 20 ml of XTT was added to the wells and allowed to incubate for 4–6 h. The colored formazan product was measured spectrophotometrically at 450 nm with correction at 650 nm, and IC50 values were determined using the GraphPad Prism 4.0 software. Data were subjected to a non-linear regression-fit analysis and IC50 values were determined as the concentration, that inhibited proliferation by 50%. All experiments were done in triplicate and the results normalized to growth of untreated cells. |

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。
