| 摘要 |
The invention relates to compounds of formula (I) where R1 represents a hydrogen or halogen atom or an -S(O)z-(C1-C4)alkyl, -S(O)z-(C1-C4)R3, -SO2-NH-(C1-C4)alkyl, -NHCO(C1-C4) alkyl, -CO(C1-C4)alkyl or -NHSO2-(C1-C4)alkyl group; m and n independently represent 0, 1 or 2; A represents a group of formula (a) or (b): where X is N or CH; R2 represents an -SO2-R3, -CO-R3 or -CO-(C1-C4)-alkyl group; R3 represents a phenyl group, optionally substituted by a (C1-C4)alkyl or (C1-C4)alkoxy group, one or two halogen atoms or a heterocycle; R4 represents a hydrogen or halogen atom or a (C1-C6)alkyl, (C1-C4)alkoxy, -COOH, -COO(C1-C4)alkyl, -CN, -CONR5R6, -NO2, -NHSO2(C1-C4)alkyl or -SO2NR5R6 group; z is 1 or 2; R5 and R6 independently represent a hydrogen atom or a (C1-C4)alkyl, phenyl or phenyl (C1-C4)alkyl group; and their salts or solvates, to a process for their preparation, to synthetic intermediates and to the pharmaceutical compositions comprising them.
