Patent ID: 7494994

Claim:
A compound selected from those of formula (I): wherein: X represents a C(O) or SO 2 group, R 1 represents: an aryl group, or an NR 3 R 4 group wherein R 3 and R 4 , which may be the same or different, each independently represent a hydrogen atom, a linear or branched (C 1 -C 6 )alkyl group, a (C 3 -C 8 )cycloalkyl group or a (C 3 -C 8 )cycloalkyl-(C 1 -C 6 )alkyl group in which the alkyl moiety is linear or branched, or R 3 and R 4 , together with the nitrogen atom carrying them, form a 5- to 8-membered ring wherein one of the carbon atoms may be replaced by a nitrogen, oxygen or sulphur atom or by an SO or SO 2 group, wherein the ring thereby defined is optionally bridged by a linear or branched (C 1 -C 6 )alkylene group and is optionally substituted by one or more identical or different groups selected from halogen, linear or branched (C 1 -C 6 )alkyl, (C 3 -C 8 )cycloalkyl, linear or branched (C 1 -C 6 )alkoxy, linear or branched (C 1 -C 6 )polyhaloalkyl, carboxy, hydroxy, cyano, oxo, nitro and amino (optionally substituted by one or more linear or branched (C 1 -C 6 )alkyl groups), R 2 represents a linear or branched (C 1 -C 6 )alkyl group, a (C 3 -C 8 )cycloalkyl group or a (C 3 -C 8 )cycloalkyl-(C 1 -C 6 )alkyl group wherein the alkyl moiety may be linear or branched, it being understood that: an aryl group means phenyl, naphthyl or biphenyl, wherein such groups may be optionally substituted by one or more identical or different groups selected from halogen, linear or branched (C 1 -C 6 )alkyl, linear or branched (C 1 -C 6 )alkoxy, linear or branched (C 1 -C 6 )polyhaloalkyl, carboxy, hydroxy, cyano, nitro and amino (optionally substituted by one or more linear or branched (C 1 -C 6 )alkyl groups), its enantiomers and diastereoisomers, and addition salts thereof with a pharmaceutically acceptable acid or base.
