NOVEL COMPOUNDS AND THEIR USE AS POSITIVE AMPA RECEPTOR MODULATORS
The invention provides novel compounds represented by general formula (I) wherein the bond represented by the broken line may be a single, double bond or absent; and if the bond is absent, then the nitrogen is substituted with a hydrogen and R2; X represents SO¿2? or C=O of CH2; Y represents -CH(R?4¿)-, -N(R4)- or -N(R4)-CH2-, O; and the meaning of R?2, R3, R4, R5, R6, R7, and R8¿ are as defined in the application. The compounds are useful as positive modulators of the AMPA-receptor.
