synthesized a series of quinoline derivatives having a characteristic 1-azabicyclo[3.3.0]octane amine ring, and performed pharmacological evaluation of them. Acetylcholine esterase inhibitory activities of these derivatives were unexpectedly weak. Tests for central nervous muscarinic cholinergic receptor binding affinity indicated that these compounds had higher affinities to muscarinic M1 receptors than to
为了发现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的1-氮杂双环[3.3.0]辛烷胺环的喹啉衍生物,并对其进行了药理学评价。这些衍生物的乙酰胆碱酯酶抑制活性出乎意料地弱。对中枢神经毒蕈碱胆碱能受体结合亲和力的测试表明,这些化合物对毒蕈碱M1受体的亲和力高于对M2受体的亲和力。还合成了一系列被1-氮杂双环[3.3.0]辛烷环取代的萘衍生物,并确定了毒蕈碱M1和M2受体的结合亲和力。这些化合物对M1受体的亲和力比喹啉衍生物和1- [N-(1-氮杂双环[3.3]。0]辛基-5-基)甲基-N-甲基氨基] -4-硝基萘具有最高的亲和力和选择性。使用东avoid碱诱导的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。
