NOVEL COMPOUNDS AND THEIR USE AS POSITIVE AMPA RECEPTOR MODULATORS

摘要

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.
