Compounds of formula (Ia), (Ib) or (Ic), wherein A represents a group having two fused rings, or a group of formula (Id), R1(m) represents up to 6 substituents, K represents -O- , -S-, CH2-, -N(R2)- or -N(COR2)- , in which R2 is H or C1 to C3 alkyl, W is a carbonyl, sulphonyl or sulphinyl group, and X is a carbonyl, sulphonyl or sulphinyl group, provided that at least one of W and X contains carbonyl, Y and Z are as given in the description and their pharmaceutically acceptable salts are ligands at CCK and/or gastrin receptors.

Composés répondant aux formules (Ia), (Ib) ou (Ic), dans lesquelles A représente un groupe à deux cycles fusionnés ou un groupe de la formule (Id), R<1>(m) représente jusqu'à 6 substituants, K représente -O-, -S-, -CH2-, -N(R<2>)- ou -N(COR<2>)-, R<2> représentant H ou alkyle C1 à C3, W représente un groupe carbonyle, sulfonyle ou sulfinyle, et X représente également un groupe carbonyle, sulfonyle ou sulfinyle, à condition que W et/ou X contienne carbonyle, et Y et Z sont tels que définis dans le descriptif. Ces composés, ainsi que leurs sels pharmaceutiquement acceptables sont des ligands de récepteurs de cholécytokinine (CKK) et/ou de gastrine.
