Patent ID: 7494995

Claim:
A compound selected from those of formula (I): wherein: R 1 represents an NR 3 SO 2 R 4 group wherein: R 3 represents a hydrogen atom or a linear or branched (C 1 -C 6 )alkyl group, R 4 represents a linear or branched (C 1 -C 6 )alkyl group, an aryl group or an NR 5 R 6 group wherein: R 5 and R 6 , which may be the same or different, each 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 5 and R 6 , 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, 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), 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 and 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 )poly-haloalkyl, 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.
