    • The subject of the invention is compounds of formula I in which Ar1 represents optionally substituted naphthyl, phenyl, quinolyl or isoquinolyl; Ar2 represents optionally substituted phenyl or thienyl; R1, R2 and R'2 represent, independently of each other, H, (C1-C4)alkyl or R1 represents nothing and N is linked to Ar2 and, optionally, R2 and R'2 form a double bond, or R1 or R2 is linked to Ar2 and represents (C1-C3)alkylene; R3 and R4, which are identical or different, represent H, (C1-C4)alkyl or form with the nitrogen atom to which they are attached a saturated (C5-C7)heterocycle; Z1 represents (C1-C12)alkylene; Q1 represents methyl, amino, (C1-C4)alkoxycarbonylamino, (C1-C4)alkylamino, di(C1-C4)alkylamino, pyrrolidinyl, piperidino, morpholino, piperazinyl, 4-(C1-C4)alkyl piperazinyl, amidino, (C1-C4)alkylamidino, guanidino, (C1-C4)alkylguanidino, pyridyl, imidazolyl, pyrimidinyl, indolyl, hydroxyl, (C1-C4)alkoxy, (C2-C8)alkoxycarbonyl, amino(C1-C4)alkyl-N-(C1-C4)alkylamino, carbamoyl or phenyl which is optionally substituted; Q2 represents H or (C1-C4)alkyl; Q3 represents H or (C1-C4)alkyl or Q1 and Q3 are linked to form a heterocycle and represent together (C2-C3)alkylene whereas Z1 represents nothing, in the form of pure enantiomers or of mixtures thereof in any proportions, as well as their salts with acids. These compounds have an affinity for the biological receptors of neuropeptide Y (NPY) which are present in the central and peripheral nervous systems.
