Described herein are D4 receptor-selective compounds of the general formula: ##STR1## wherein: A and B are independently selected, optionally substituted, saturated or unsaturated 5- or 6-membered, homo- or heterocyclic rings; X.sub.1 is selected from CH.sub.2, O, NH, S, C.dbd.O, CH--OH, CH--N(C.sub.1-4 alkyl).sub.2, C.dbd.CHCl, C.dbd.CHCN, N-C.sub.1-4 alkyl, N-acetyl, SO.sub.2 and SO; X.sub.2 -- is selected from N.dbd., CH.sub.2 --, CH.dbd., C(O)--, O--, and S--; R.sub.1 represents C.sub.1-4 alkyl; Y is selected from CH and N; n is 0, 1 or 2; q is 1 or 2; R.sub.2 is C.sub.1-6 alkyl optionally incorporating a heteroatom selected from N, O and S; D is cyclohexane or benzene; and E is a saturated or unsaturated 5- or 6-membered heterocycle incorporating 1, 2 or 3 heteroatoms selected from O, N, and S, wherein E is optionally substituted with 1 or 2 substituents selected from halogen, C.sub.1-4 alkyl and halogen-substituted C.sub.1-4 alkyl; and acid addition salts, solvates and hydrates thereof. Their use as ligands for dopamine receptor identification and in a drug screening program, and as pharmaceuticals to treat indications in which the D4 receptor is implicated, such as schizophrenia, is also described.
