Patent ID: 7388022

Claim:
A compound selected from those of formula (I): wherein: n represents an integer from 1 to 6 inclusive, R 1 and R 2 , which may be identical or different, each independently of the other represent a hydrogen atom, a linear or branched (C 1 -C 6 )alkyl group or an aryl-(C 1 -C 6 )alkyl group in which the alkyl moiety may be linear or branched, R 3 and R 4 , which may be identical or different, each independently of the other represent a hydrogen atom or a linear or branched (C 1 -C 6 )alkyl group, R 5 and R 6 , which may be identical or different, each independently of the other represent a hydrogen atom or a linear or branched (C 1 -C 6 )alkyl, halogen, hydroxy, linear or branched (C 1 -C 6 )alkoxy, cyano, nitro, linear or branched (C 2 -C 6 )acyl, linear or branched (C 1 -C 6 )alkoxycarbonyl, linear or branched (C 1 -C 6 )trihaloalkyl or linear or branched (C 1 -C 6 )trihaloalkoxy group or an amino group optionally substituted by one or two linear or branched (C 1 -C 6 )alkyl groups, R 7 represents a hydrogen atom, a linear or branched (C 1 -C 6 )alkyl group or an aryl-(C 1 -C 6 )alkyl group in which the alkyl moiety may be linear or branched, it being understood that an aryl group means phenyl, biphenyl, naphthyl, dihydronaphthyl, tetrahydronaphthyl, indanyl or indenyl group, each of the groups being optionally substituted by one or more identical or different groups selected from halogen, linear or branched (C 1 -C 6 )alkyl, hydroxy, cyano, nitro, linear or branched (C 1 -C 6 )alkoxy, linear or branched (C 2 -C 7 )acyl, linear or branched (C 1 -C 6 )alkoxycarbonyl, linear or branched (C 1 -C 6 )trihaloalkyl and linear or branched (C 1 -C 6 )trihaloalkoxy groups and amino groups optionally substituted by one or two linear or branched (C 1 -C 6 )alkyl groups, its enatiomers, diastereoisomers and additional salts thereof with a pharmaceutically acceptable acid or base.
