Patent ID: 7498330

Claim:
A compound of formula (I): wherein: represents 1-oxidopyridyl substituted by the remainder of the molecule in any one of the positions 2, 3 and 4, m and n, which are identical or different, each represent an integer of from 1 to 3, R 1 represents hydrogen or linear or branched (C 1 -C 6 )alkyl, R 2 and R 3 , which may be identical or different, each represent an atom or group selected from hydrogen, halogen, linear or branched (C 1 -C 6 )alkyl, hydroxy, linear or branched (C 1 -C 6 )acyloxy and linear or branched (C 1 -C 6 )alkoxy, or, together with the carbon atom carrying them, form a cycloalkane having from 3 to 6 carbon atoms, R 4 and R 5 each represent hydrogen, or are adjacent and, together with the carbon atoms carrying them, form a benzo ring, Ar represents aryl or heteroaryl, or enantiomers, or an addition salt thereof with a pharmaceutically acceptable acid, it being understood that: “aryl” is phenyl, optionally substituted by one or more identical or different groups selected from: halogen, linear or branched (C 1 -C 6 )alkoxy, hydroxy, carboxymethoxy, and carbamoylmethoxy optionally N-substituted by one or two groups selected from linear or branched (C 1 -C 6 )alkyl, hydroxy-(C 1 -C 6 )alkyl in which the alkyl moiety may be linear or branched, alkoxyalkyl in which the alkoxy and alkyl moieties are each linear or branched C 1 -C 6 , and pyridylalkyl in which the alkyl moiety is linear or branched C 1 -C 6 , and “heteroaryl” is thienyl or triazolyl optionally substituted by oxo.
