Abstract

Compounds of formula (I) and their pharmaceutically active salts are gastrin and CCK receptor ligands, where Ar is a monocyclic aromatic group, R.sup.1 is halo, amino, nitro, cyano, sulphamoyl, sulphonyl, trifluoromethyl, C.sub.1 to C.sub.3 alkyl, C.sub.1 to C.sub.3 alkylamino, C.sub.1 to C.sub.3 dialkylamino, phenyl, substituted phenyl, C.sub.1 to C.sub.3 alkoxy, hydroxy, esterified hydroxy, C.sub.1 to C.sub.3 hydroxyalkyl, C.sub.1 to C.sub.3 alkylcarboxyamino, carboxy, esterified carboxy and amidated carboxy, m is 0, 1, 2, 3, or 4, provided that m is not more than 2 unless R.sup.1 is exclusively halo, x+y=0 or 1, R.sup.2 and R.sup.4 independently are II, or C.sub.1 to C.sub.3 alkyl, R.sup.3 is H or C.sub.1 to C.sub.15 hydrocarbyl, where one or more hydrogen atoms of die hydrocarbyl group may be replaced by a halogen atom, and where up to two of the carbon atoms may be replaced by a nitrogen, oxygen or sulphur atom, provided that R.sup.3 does not contain a --O--O-- group, R.sup.5 is H or C.sub.1 to C.sub.3 alkyl, U is a cyclic moiety, selected from the group consisting of aryl, aromatic heterocyclic, non-aromatic heterocyclic, and cycloalkyl groups, where the aryl or aromatic grou…
