Piperidine-4 sulphonamide compounds

A compound selected from those of formula (I):

• 33
• wherein:
• R1 represents hydrogen or linear or branched (C1-C6)alkyl,
• R2a and R2b, which may be identical or different, each independently of the other represents a group selected from hydrogen, halogen, linear or branched (C1-C6)alkyl, hydroxy, linear or branched (C1-C6)alkoxy, linear or branched (C1-C6)trihaloalkyl, cyano, nitro, amino, linear or branched (C1-C6)alkylamino, and di-(C1-C6)alkyl-amino in which each alkyl moiety is linear or branched,
• R3 represents hydrogen or hydroxy,
• X represents oxygen or methylene,
• V represents a linear or branched (C1-C6)alkylene chain optionally containing one or more unsaturations and being optionally substituted by one or more identical or different groups selected from halogen, hydroxy and linear or branched (C1-C6)alkoxy,
• U represents a bond or a linear or branched (C1-C6)alkylene chain,
• W represents a group selected from aryl and heteroaryl, each of those groups being optionally substituted by one or more identical or different groups selected from halogen, linear or branched (C1-C6)alkyl, hydroxy, linear or branched (C1-C6)alkoxy, linear or branched (C1-C6)trihaloalkyl, oxo, cyano, nitro, amino, linear or branched (C1-C6)-alkylamino, di-(C1-C6)alkylamino in which each alkyl moiety is linear or branched, pyridyl, linear or branched (C1-C6)alkylcarbonyl, aminocarbonyl (the amino moiety being optionally substituted by one or two identical or different linear or branched (C1-C6)alkyl), linear or branched (C1-C6)alkoxycarbonyl, linear or branched (C1-C6)trihaloalkylcarbonyl, linear or branched (C1-C6)alkylsulphonyl, and linear or branched (C1-C6)-trihaloalkylsulphonyl, its isomers, its hydrates, its solvates and addition salts thereof with a pharmaceutically acceptable acid or base,
• it being understood that:
• “aryl group” is understood to mean a group selected from phenyl, biphenyl, naphthyl, dihydronaphthyl, tetrahydronaphthyl, indanyl and indenyl,
• “heteroaryl group” is understood to mean a monocyclic aromatic or bicyclic system having from 5 to 12 ring members and containing from 1 to 3 identical or different hetero atoms selected from oxygen, nitrogen and sulphur, and in the case of a bicyclic system one of the rings has an aromatic character, it being possible for the other ring to be aromatic or partially hydrogenated.
