There are disclosed compounds of the formula
where R₁ is loweralkoxycarbonyl, -CH₂OH or -CONR₃R₄, R₃ and R₄ being independently hydrogen, loweralkyl or arylloweralkyl; and R₂ is -CH₂CH=CH₂,
R₅ and R₆ being independently loweralkyl or alternatively the group -NR₅R₆ as a whole being
R₇ being hydrogen, loweralkyl or arylloweralkyl; and a process for their preparation. The compounds are useful for enhancing cholinergic activity in mammals and hence for the treatment of various memory dysfunctions characterized by decreased cholinergic function such as Alzheimer's disease, and can, therefore, be used as medicaments.
公开了如下式子的化合物
其中 R₁ 是低级烷氧基羰基、-CH₂OH 或 -CONR₃R₄,R₃ 和 R₄ 独立地是氢、低级烷基或芳基低级烷基;R₂ 是 -CH₂CH=CH₂、
R₅和 R₆ 独立为低级烷基,或者作为一个整体的基团 -NR₅R₆ 是
R₇为氢、低级烷基或芳基低级烷基;及其制备方法。这些化合物有助于增强哺乳动物的胆碱能活性,从而治疗以胆碱能功能下降为特征的各种记忆功能障碍,如阿尔茨海默氏症,因此可用作药物。
