function in the disease provides a basis for examining muscarinic agonists as potential therapeutic agents. This paper describes the design and synthesis of novel azabicyclic methyl esters as ligands for the muscarinic receptor. Replacement of the methyl ester by a 3-methyl-1,2,4-oxadiazole ring produces potent metabolically more stable muscarinic agonists capable of penetrating the central nervous system
与阿尔茨海默氏型痴呆症相关的认知缺陷与疾病中胆碱能功能的丧失之间的联系为检查毒蕈碱激动剂作为潜在治疗剂提供了基础。本文描述了新型的氮杂双环甲酯作为毒蕈碱受体配体的设计和合成。用3-甲基-1,2,4-恶二唑环取代甲酯可产生有效的代谢更稳定的毒蕈碱激动剂,能够穿透中枢神经系统。这些化合物相对于相应的甲酯通常显示出改善的亲和力。3-甲基1,2,4-恶二唑7b的亲和力是乙酰胆碱的4倍。关于氮杂双环的大小和几何形状以及杂芳族环的电子性质,讨论了受体亲和力。
