Claim:
A compound selected from those of formula (I): wherein: R 1 , R 2 , R 3 and R 4 , which may be the same or different, each represent an atom or group selected from hydrogen, halogen, linear or branched C 1 -C 6 alkyl, linear or branched C 1 -C 6 alkoxy, phenyl and cyano, X represents a bond, an oxygen atom or a group selected from —(CH 2 ) m —, —OCH 2 — and —NR 5 —, m represents 1 or 2, R 5 represents a hydrogen atom or a group selected from linear or branched C 1 -C 6 alkyl, COR 6 and CO 2 R 6 , R 6 represents a linear or branched C 1 -C 6 alkyl group, Y represents NR 7 , R 7 represents a hydrogen atom or a group selected from COR 9 and linear or branched C 1 -C 6 alkyl, the alkyl group being optionally substituted by a 5-oxo-4,5-dihydro-1H-1,2,4-triazol-3-yl or 2,3-dihydro-1,4-benzodioxin-2-yl group, R 9 represents a group selected from linear or branched C 1 -C 6 alkyl and aryl, Z represents a nitrogen atom, n represents 2, Ak represents a linear or branched C 1 -C 6 alkylene chain, Ar represents an aryl group, its optical isomers, and addition salts thereof with a pharmaceutically acceptable acid, it being understood that an aryl group means phenyl, biphenylyl or naphthyl, each of the groups optionally being 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, linear or branched C 1 -C 6 trihaloalkyl and linear or branched C 1 -C 6 trihaloalkoxy.
