Patent ID: 7947852

Claim:
A compound selected from those of formula (I): wherein: R 1 represents a linear or branched (C 1 -C 6 )alkyl group, a linear or branched (C 1 -C 6 )alkenyl group, a linear or branched (C 1 -C 6 )haloalkyl group, a linear or branched (C 1 -C 6 )polyhaloalkyl group, a (C 3 -C 8 )cycloalkyl group, a (C 3 -C 8 )cycloalkyl-(C 1 -C 6 )alkyl group in which the alkyl moiety may be linear or branched, an aryl group, an aryl-(C 1 -C 6 )alkyl group in which the alkyl moiety may be linear or branched, a heteroaryl group or a heteroaryl-(C 1 -C 6 )alkyl group in which the alkyl moiety may be linear or branched, X represents a N—OR 2 group wherein R 2 represents a hydrogen atom or a linear or branched (C 1 -C 6 )alkyl group, it being understood that: the oxime ═N—OR 2 may be of Z or E configuration, “aryl” means phenyl, naphthyl or biphenyl, “heteroaryl” means a mono- or bi-cyclic aromatic group having from 1 to 3 hetero atoms selected from oxygen, sulphur and nitrogen, wherein the aryl and heteroaryl groups may be optionally substituted by 1 to 3 groups selected from linear or branched (C 1 -C 6 )alkyl, linear or branched (C 1 -C 6 )alkoxy, hydroxy, carboxy, formyl, nitro, cyano, linear or branched (C 1 -C 6 )haloalkyl, linear or branched (C 1 -C 6 )polyhaloalkyl, alkyloxycarbonyl and halogen, and enantiomers, diastereoisomers, and addition salts thereof with a pharmaceutically acceptable acid or base.
