effective against Alzheimer's disease, we synthesized a series of aniline derivatives having a characteristic cyclic amine, 1-azabicyclo[3.3.0]octane ring, and evaluated their binding affinity for the central muscarinic cholinergic receptor. Among these compounds which showed high affinity to the M1 receptor, N-[2-(1-Azabicyclo[3.3.0]octan-5-yl)ethyl]-2-nitroaniline (9f fumarate, SK-946) showed the highest
为了开发对阿尔茨海默氏病有效的药物,我们合成了一系列具有特征性环胺的苯胺衍生物1-氮杂双环[3.3.0]辛烷环,并评估了它们对中央毒蕈碱胆碱能受体的结合亲和力。在这些对M1受体表现出高亲和力的化合物中,N- [2-(1-氮杂双环[3.3.0]辛烷-5-基)乙基] -2-硝基苯胺(富马酸酯9f,SK-946)显示出最高的亲和力。使用东avoid碱诱导的痴呆小鼠的被动回避测试评估了该化合物改善认知功能的能力。还通过1-氮杂双环[3.3.0]辛烷环的扩环合成了一些具有1-氮杂双环[3.3.1]壬烷环的苯胺,并显示出对中央毒蕈碱胆碱能受体的高亲和力。
