The invention provides N-cyclic sulfonamido compounds and salts of Formula I:
wherein A is as described in the specification and R
1
and R
2
combine to form a [3.3.1] or a [3.2.1] ring system, where the nitrogen is attached to the two bridgehead carbons, and the [3.3.1] or [3.2.1] ring systems are optionally fused with an heteroaryl or heterocycloalkyl ring. Compounds of Formula I are useful in treating or preventing cognitive disorders, such as Alzheimer's Disease. The invention also encompasses pharmaceutical compositions comprising compounds of Formula I, methods of treating cognitive disorders, such as Alzheimer's disease, and the intermediates useful in preparing the compounds of Formula I.
本发明提供了式I的N-环磺酰胺化合物和盐,其中A如说明书所述,且R1和R2结合形成[3.3.1]或[3.2.1]环系统,其中氮原子连接到两个桥头碳原子,并且[3.3.1]或[3.2.1]环系统可以与杂环
芳烃或杂环烷基环融合。I式化合物在治疗或预防认知障碍,如阿尔茨海默病方面有用。本发明还包括包含I式化合物的制药组合物,治疗认知障碍,如阿尔茨海默病的方法,以及制备I式化合物的中间体。
