细胞系 | PC12 cells |
方法 | Cell viability assay Cell viability was assayed using the Cell Counting Kit-8 (CCK-8; Dojindo Co., Kumamoto, Japan) according to the manufacture's protocol. Briefly, PC12 Cells were planted in 96-well plates at a density of 5000 cells per cm2 and incubated at 37 ℃ in a 5% CO2 humidified atmosphere for 24 h. Then the cells were treated with TBHP, FG-4592 and YC-1 as described above. After treatment the cells were washed with PBS, then 100 μL of DMEM and 10 μL of CCK-8 solution was added to each well of 96-well plates, and the plates was incubated for an additional 1 h. The absorbance was then measured at the wavelength of 450 nm by a microplate reader to assess the number of viable 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。
