| 细胞系 | CCl39 cells expressing FLAG-ERK5 |
| 方法 | Cells were serum-starved for 16 h prior to the addition of PD184352, or an equivalent of DMSO vehicle control for 90 min. Single dishes of cells were then stimulated with 10% FBS for 15 min and immune-complex kinase assays performed with either myelin basic protein (MBP; ERK1) or GST-MEF2C (ERK5), as a substrate. PD184352 inhibited FBS-induced ERK1 activation with an IC50 below 1 μM, whereas even a dose of 20 μM PD184352 was insufficient to inhibit ERK5 activity, induced in the same manner and assayed from the same cell extracts as ERK1. |

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。
