Patent ID: 7741320

Claim:
A compound selected from those of formula (I): wherein: R Cy represents: a (C 3 -C 8 )cycloalkyl group which is unsubstituted or substituted by one or more identical or different groups selected from linear or branched (C 1 -C 6 )alkyl which is unsubstituted or substituted by one or more halogen atoms; linear or branched (C 1 -C 6 )alkoxy; hydroxy; and amino which is unsubstituted or substituted by one or two linear or branched (C 1 -C 6 )alkyl groups; or a (C 3 -C 8 )cycloalkyl-(C 1 -C 6 )alkyl group in which the alkyl moiety is linear or branched and which is unsubstituted or substituted on the cyclic moiety by one or more identical or different groups selected from linear or branched (C 1 -C 6 )alkyl which is unsubstituted or substituted by one or more halogen atoms; linear or branched (C 1 -C 6 )alkoxy; hydroxy; and amino which is unsubstituted or substituted by one or two linear or branched (C 1 -C 6 )alkyl groups; R 1 , R 2 , R 3 and R 4 , which may be the same or different, each represent a hydrogen atom; a halogen atom; a nitro group; a cyano group; a hydroxy group; a linear or branched (C 1 -C 6 )alkyl group which is unsubstituted or substituted by one or more halogen atoms; a linear or branched (C 1 -C 6 )cyanoalkyl group; a linear or branched (C 1 -C 6 )hydroxyalkyl group; a linear or branched (C 1 -C 6 )alkoxy group which is unsubstituted or substituted by one or more halogen atoms; a linear or branched (C 1 -C 6 )alkylthio group; a carboxy group; a linear or branched (C 1 -C 6 )alkoxycarbonyl group; an aryloxycarbonyl group; a linear or branched (C 1 -C 6 )acyl group; an amino group which is unsubstituted or substituted by one or two linear or branched (C 1 -C 6 )alkyl groups or by a linear or branched (C 1 -C 6 )acyl group; an aminocarbonyl group which is unsubstituted or substituted by one or two linear or branched (C 1 -C 6 )alkyl groups; an arylaminocarbonyl group; or a linear or branched (C 1 -C 6 )alkylsulphonylamino group; its enantiomers, diastereoisomers, and addition salts thereof with a pharmaceutically acceptable acid or base, it being understood that: “aryl” means a phenyl group which is unsubstituted or substituted by one or more identical or different groups selected from linear or branched (C 1 -C 6 )alkyl which is unsubstituted or substituted by one or more halogen atoms; linear or branched (C 1 -C 6 )alkoxy; hydroxy; and amino which is unsubstituted or substituted by one or two linear or branched (C 1 -C 6 )alkyl groups.
