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 R<2>; X represents SO2 or C=O of CH2; Y represents -CH(R<4>)-, -N(R<4>)- or -N(R<4>)-CH2-, O; and the meaning of R<2>, R<3>, R<4>, R<5>, R<6>, R<7>, and R<8> are as defined in the application. The compounds are useful as positive modulators of the AMPA-receptor. |
