[ 靶点 ]

Acetylcholinesterase:0.7 nM (IC50)

Acetylcholinesterase:0.12 nM (Ki)

Butyrylcholinesterase:7 μM (IC50)

[体外研究]

氯化铵以快速可逆的方式抑制乙酰胆碱酯酶(AChE),并显示出对hAChE的强烈抑制,抑制常数Ki为0.12nM[1]。氯化铵对BChE具有抑制作用,IC50值为7μM(hBChE)[2]。

[体内研究]

氯化铵(6 mg/kg；p.o；每日；30-60天)在长期给药时对神经肌肉传递产生不良影响,并在重症肌无力小鼠模型中诱导对刺激的超敏反应[3]。氯化铵(6 mg/kg；p.o；每日；14 d)可减少运动终板中的AChR数量[3]。动物模型：患有重症肌无力的雌性Sprague-Dawley大鼠(体重250g)[3]剂量：6mg/kg给药：口服灌胃；每日的14、30、60、90、360天(提前24小时停止给药)结果：在第30-60天,大鼠的一般活动减少,对刺激过敏,但这些行为在第90天消失。导致突触后皱褶变性和简化,突触裂变宽,突触后小泡数量增加,第360天突触后膜中的AChR数量减少。
