细胞系 | NCI-H929, NIH-3T3/LISN, COLO 205, HT29, and BxPC3 cells |
方法 | Cell proliferation assays. Cells were seeded in 96-well dishes, incubated overnight at 37°C, and treated with various concentrations of GSK1904529A for 72 h. For the NIH-3T3/LISN proliferation assays, cells were seeded on collagen-coated 96-well tissue culture plates (BD Biosciences) and allowed to adhere for 24 h. The tissue culture medium was replaced with serum-free medium and the cells were treated with DMSO or GSK1904529A for 2 h. IGF-I (30 ng/mL) was added and the cells were incubated at 37°C for 72 h. Cell proliferation was quantified using the CellTiter-Glo Luminescent Cell Viability Assay (Promega) following the manufacturer's recommendations. IC50 values were determined by using a four-parameter curve fit software package (XLfit4). |

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。
