The subject of the invention is the compounds of formula I ##STR1## in which Ar.sub.1 represents naphtyl, phenyl, quinolyl or isoquinolyl optionally substituted; Ar.sub.2 represents a phenyl or thienyl optionally substituted; R.sub.1, R.sub.2 and R'.sub.2 are independently of each other, H or (C.sub.1 -C.sub.4)alkyl; R.sub.1 represents nothing and N is attached to Ar.sub.2, and optionally R.sub.2 and R'.sub.2 form a double bond; or R.sub.1 or R.sub.2 is attached to Ar.sub.2 and represents a (C.sub.1 -C.sub.3)alkylene; R.sub.3 and R.sub.4, which are identical or different, represent H, (C.sub.1 -C.sub.4)alkyl or form, with the nitrogen atom to which they are attached, a (C.sub.5 -C.sub.7) saturated heterocycle selected from pyrrolidine, piperidine and hexahydroazepine; Z.sub.1 represents a (C.sub.1 -C.sub.12)alkylene, optionally interrupted or extended by a (C.sub.5 -C.sub.7)cycloalkyl or phenyl; Q.sub.1 represents methyl, amino, alkoxycarbonylamino, alkylamino, dialkylamino, a (C.sub.5 -C.sub.7) saturated heterocyclic amino group, amidino, alkylamidino, guanidino, alkylguanidino, pyridyl, imidazolyl, pyrimidinyl, indolyl, hydroxy, alkoxy, (C.sub.2 -C.sub.8)alkoxycarbonyl, amino(C.sub.1 -C.sub.4)alkyl-N-(C.sub.1 -C.sub.4)alkylamino or carbamoyl, or phenyl optionally substituted; Q.sub.2 represents H or alkyl; Q.sub.3 represents H or (C.sub.1 -C.sub.4)alkyl; or Q.sub.1 and Q.sub.3 are attached to form a heterocycle and together represent a (C.sub.2) or (C.sub.3)alkylene, whereas Z.sub.1 represents nothing, in the form of pure enantiomers or mixtures thereof in any proportions, as well as their salts with acids. These compounds have an affinity for the biological receptors of neuropeptides Y (NPY), which are present in the central and peripheral nervous system.
