Patent ID: 7442692

Claim:
A compound selected from those of formula (I): wherein: R 3 represents a hydrogen atom, and R 1 and R 2 together with the carbon atoms carrying them form a benzene or naphthalene ring structure, each of the ring structures being optionally substituted by one or more identical or different substituents selected from hydrogen, halogen and linear or branched C 1 -C 6 alkyl optionally substituted by one or more halogen atoms, or R 1 represents a hydrogen atom, and R 2 and R 3 together with the carbon atoms carrying them form a benzene or naphthalene ring structure, each of the ring structures being optionally substituted by one or more identical or different substituents selected from hydrogen, halogen and linear or branched C 1 -C 6 alkyl optionally substituted by one or more halogen atoms, n represents 1 or 2, —X— represents a group selected from —(CH 2 ) m —O-Ak-, —(CH 2 ) m —NR 4 -Ak-, —(CO)—NR 4 -Ak- and —(CH 2 ) m —NR 4 —(CO)—, m represents an integer between 1 and 6 inclusive, Ak represents a linear or branched C 1 -C 6 alkylene chain optionally substituted by a hydroxy group, and R 4 represents a hydrogen atom, or linear or branched C 1 -C 6 alkyl group, Ar represents aryl or heteroaryl group, and its enantiomers, diasteroisomers, and addition salts thereof with a pharmaceutically acceptable acid, it being understood that: an aryl group means phenyl, biphenylyl or naphthyl, each of those groups being 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, hydroxy, cyano and linear or branched C 1 -C 6 trihaloalkyl, a heteroaryl group means thienyl or pyridyl, each of those groups being 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, hydroxy and linear or branched C 1 -C 6 trihaloalkyl.
