    • The present invention relates to 2-aminopyridine derivatives of the formula I: 1 or pharmaceutically acceptable salts thereof, wherein A and B are each independently H, or together, A and B form a ring fused to the phenyl ring, said ring being saturated or unsaturated and containing from 5 to 7 ring member atoms, where said ring member atoms may optionally comprise from 1 to 2 heteroatoms selected independently from the group consisting of N, O or S, provided that no two adjacent ring members are heteroatoms; X is oxygen or a single bond; Y is (C1-C6)alkyl; R1 is hydrogen, (C1-C6)alkyl or a (C1-C6 alkyl) group substituted with nullNR2R3 wherein R2 and R3 are either selected independently from the group consisting of H, alkyl, aryl, aralkyl or tetrahydronaphthalene, wherein said aryl group or said aryl moiety of said aralkyl group is phenyl or naphthyl, said alkyl group or said alkyl moiety of said aralkyl group contains from one to six carbon atoms and is straight-chained or branched, and said aryl group, said tetrahydronaphthalene or said aryl moiety of said aralkyl group is optionally substituted with from one to three of halogen, nitro, cyano, amino, (C1-C4)alkoxy and (C1-C4)alkylamino moieties, or R2 and R3 form, together with the nitrogen to which they are attached, a heterocyclic ring, or a cyclic or bicyclic ring which is saturated or unsaturated. The compounds of the invention have the ability to inhibit the activity of nitric oxide synthases (NOS), and hence, are useful in the treatment of diseases, conditions and disorders of the central nervous system, among others.
    • 本发明涉及式I的2-氨基吡啶衍生物或其药学上可接受的盐,其中A和B各自独立地为H,或者一起A和B形成与苯环稠合的环,所述环为饱和或不饱和的 并且含有5至7个环成员原子,其中所述环成员原子可以任选地包含1至2个独立地选自N,O或S的杂原子,条件是不存在两个相邻的环成员是杂原子; X是氧或单键; Y是(C 1 -C 6)烷基; R 1是氢,(C 1 -C 6)烷基或被-NR 2 R 3取代的(C 1 -C 6烷基)基团,其中R 2和R 3独立地选自H,烷基,芳基,芳烷基或四氢萘,其中所述芳基 或所述芳烷基的所述芳基部分是苯基或萘基,所述烷基或所述芳烷基的所述烷基部分含有1至6个碳原子并且是直链或支链的,并且所述芳基,所述四氢萘或所述芳基部分 的所述芳烷基任选被1至3个卤素,硝基,氰基,氨基,(C 1 -C 4)烷氧基和(C 1 -C 4)烷基氨基部分取代,或者R 2和R 3与氮原子一起形成 杂环,或饱和或不饱和的环状或双环。 本发明的化合物具有抑制一氧化氮合酶(NOS)活性的能力,因此可用于治疗中枢神经系统的疾病,病症和病症等。
