方法 | Proliferation assays. Cell proliferation was evaluated using the tetrazolium compound 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)2-(4-sulfophenyl)-2H-tetrazolium, inner salt (MTS), according to the manufacturer’s instructions (CellTiter 96 Aqueous One Solution Cell Proliferation Assay). Cell numbers were quantified using a Coulter counter. Cells were cultured in 96-well plates: each well contained 104 cells in a total volume of 100 μl. Each assay included one plate The plate included blank wells (0 cells/0.1 ml), control wells (104 cells /0.1 ml), control wells with acetonitrylo, control wells treated with aprepitant and control wells treated with the most effective SP concentration and aprepitant. The plates were inoculated with aprepitant (5–70 μM for tumor cell lines) and were incubated for the first doubling time specific for each tumor cell line. The plates were also inoculated the most mitogenic exogenous SP nM concentration with the fifty-percent inhibition concentration (IC50) of aprepitant μM concentration approximately and without aprepitant for their first doubling times respectively. For the proliferation assay, 20 μl of the MTS reagent was added to each well 90 min before reading the samples on a multiscanner microplate reader (TECAN Spectra classic, Barcelona, Spain) at 492 nm. The quantity of product, as measured by optical density, is directly proportional to the number of living cells. |

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。
