Claim:
Compounds of the general formula (I) in which: A is chosen among carbocyclic aromatic groups, heterocyclic aromatic groups, and arylC 1-4 alkyl; R 1 is chosen among: hydrogen, arylC 1-7 alkyl, optionally substituted on the aryl moiety with one or more groups chosen among hydroxy, C 1-4 alkoxy, halogen, haloC 1-4 alkyl; heterocyclylC 1-7 alkyl, optionally substituted on the heterocyclyl moiety with one or more groups chosen among C 1-4 alkyl and hydroxy; C 1-7 alkyl, optionally interrupted by an oxygen or sulphur atom or optionally substituted at any position by one or more groups chosen among hydroxy, thio, amino, carboxyl, aminocarbonyl, guanidinyl; R 2 is chosen among hydrogen, C 1-4 alkyl, arylC 1-4 alkyl and phenyl; or else R 1 and R 2 , taken together, form a saturated carbocyclic ring containing from 3 to 8 carbon atoms; R 3 is chosen among hydrogen, C 1-4 alkyl, arylC 1-4 alkyl, CONH 2 and COOR 5 in which R 5 is chosen between hydrogen and C 1-4 alkyl; R 4 is chosen among hydrogen, C 1-4 alkyl, aryl, arylC 1-4 alkyl and heterocyclyl; n is 2, 3 or 4; in the form of a racemic mixture or in the form of enantiomers, and pharmaceutically acceptable salts thereof.
