    摘要: Compounds of formula I: wherein A is a heterocycle containing a nitrogen atom and optionally saturated or unsaturated and optionally further substituted by an oxo group (═O); R is: hydrogen, cyano, (C1-4)alkoxycarbonyl, carbamoyl; optionally substituted (C4-7)-cycloalkyl, aryl or heterocycle; (C1-8)alkyl, (C2-8)alkenyl or (C2-8)alkynyl optionally branched and/or substituted by (C4-7) cycloalkyl, aryl or heterocycle; aryloxy, heterocyclyloxy, aryl(C1-4)alkoxy, heterocyclyl(C1-4)alkoxy, amino substituted by one or two (C1-4)alkyl group(s), aryl-amino, heterocyclyl-amino, aryl(C1-4)alkyl-amino, or heterocyclyl(C1-4)alkylamino; Y is methylene or ethylene; W is an optionally substituted aryl or heterocycle; R1 is hydrogen, (C4-7)cycloalkyl or a (C2-8)alkyl, (C2-8)alkenyl or (C2-8)alkynyl group optionally substituted by hydroxy, oxo, (C4-7)cycloalkyl, aryl or heterocycle, and optionally interrupted by one or more heteroatom(s) or heterogroup(s); R2 is a (C1-6)alkyl or polyfluoro(C1-6)alkyl group; the N→O derivatives of the compounds of formula I and the pharmaceutically acceptable salts thereof. The compounds of formula (I) are PDE 4 inhibitors and may be used in compositions and methods involving PDE 4 inhibition.
