Following the discovery of the weak, competitive and reversible acetylcholinesterase (AChE)-inhibiting activity of minaprine (3c) (IC50 = 85 microM on homogenized rat striatum AChE), a series of 3-amino-6-phenylpyridazines was synthesized and tested for inhibition of AChE. A classical structure-activity relationship exploration suggested that, in comparison to minaprine, the critical elements for high
发现米那匹林(3c)的弱,竞争性和可逆性乙酰胆碱酯酶(AChE)抑制活性(对均质大鼠纹状体AChE的IC50 = 85 microM)后,合成了一系列3-氨基-6-苯基哒嗪并测试了其抑制作用AChE。一项经典的构效关系研究表明,与米萘普林相比,高乙酰胆碱酯酶抑制的关键因素如下:(i)中央哒嗪环的存在;(ii)亲脂性阳离子头的必要性;(iii)改变哒嗪环与阳离子头之间的碳原子数为2至4-5。在研究的所有衍生物中,3- [2-(1-苄基哌啶-4-基)乙基氨基] -6-苯基哒嗪(3y)在纯化的AChE(电鳗)上的IC50为0.12 microM,
