Patent

CA 2632670

The invention provides N-cyclic sulfonamido compounds and salts of Formula (I): wherein A is as described in the specification and R1 and R2 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).

La présente invention se rapporte à des composés sulfonamides N-cycliques et à leurs sels, qui sont représentés par la formule (I). Dans ladite formule, A est tel que défini dans le descriptif de l'invention, et R1 et R2 se combinent pour former un système cyclique [3.3.1] ou [3.2.1], l'azote étant relié aux deux carbones têtes de pont, et les systèmes cycliques [3.3.1] ou [3.2.1] étant éventuellement fusionnés avec un cycle hétéroaryle ou hétérocycloalkyle. Les composés représentés par la formule (I) sont utiles pour traiter ou prévenir des troubles cognitifs tels que la maladie d'Alzheimer. L'invention concerne également des compositions pharmaceutiques contenant des composés représentés par la formule (I), des méthodes destinées à traiter des troubles cognitifs tels que la maladie d'Alzheimer, et des intermédiaires utiles pour préparer les composés représentés par la formule (I).
