H 89 2HCl是一种有效的PKA抑制剂,Ki为48 nM,作用于PKA比作用于PKG选择性高10倍,比作用于PKC, MLCK,钙调蛋白激酶II和酪蛋白激I/II选择性高500倍。
H 89 2HCl is a potent PKA inhibitor with Ki of 48 nM, 10-fold selective for PKA than PKG, greater than 500-fold selectivity than PKC, MLCK, calmodulin kinase II and casein kinase I/II.
1% DMSO+30% polyethylene glycol+1% Tween 80
~30 μM
20或200mg/kg s.c.
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,已知某工具药用于小鼠的剂量为88 mg/kg , 则用于大鼠的剂量换算方法:将88 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到该药物用于大鼠的等效剂量44 mg/kg。
