Molecular modification of the potent and selective muscarinic antagonist 2‐ethylthio‐2,2‐diphenylacetic acid N,N‐diethylamino‐ethyl ester was performed in order to identify M2 selective antagonists able to cross the blood brain barrier and potentially useful in the treatment of Alzheimer's disease. Modifications included substitution or hydrogenation of one of the phenyl rings as well as their incorporation
对强效选择性毒蕈碱拮抗剂 2-乙硫基-2,2-二苯乙酸 N, N-二乙氨基-乙酯进行了分子修饰,以确定能够穿过血脑屏障并可能用于治疗的 M2 选择性拮抗剂阿尔茨海默氏病。修饰包括苯环之一的取代或氢化以及它们在三环系统中的结合。一般而言,引入的变化对亲和力和选择性都是有害的。某些化合物中仅存在适度的 M2 选择性,另一方面,这些化合物带有季铵基团,从而阻止它们渗透到大脑中。
