PNU-120596是一种有效的α7 nAChR变构调节剂,EC50为216 nM。
PNU-120596 is a positive allosteric modulator of α7 nAChR with EC50 of 216 nM. This modulator increases the frequency of acetylcholine-evoked GABAergic postsynaptic currents in pyramidal neurons, which can be suppressed by TTX. In addition, studies show that PNU 120596 increases the average time the channel of AChR is open, but does not have any effect on the selectivity of ions flowing through the channel. Furthermore, PNU 120596 has little effect on α4β2, α3β4 and α9α10 receptors.

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。
