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--; Y is selected from N and CH; R.sub.1 represents C.sub.1-4 alkyl; n is 0, 1 or 2; q is 1 or 2; and Z is C.sub.5-10 alkyl optionally substituted with OH, halo, C.sub.1-4 alkyl or C.sub.1-4 alkoxy and optionally incorporating a heteroatom selected from O, N and S; 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.
本文描述了D4受体选择性化合物的一般公式:##STR1## 其中:A和B分别选自选择性取代的饱和或不饱和的5或6元杂环;X.sub.1选自CH.sub.2,O,NH,S,C.dbd.O,CH--OH,CH--N(C.sub.1-4烷基).sub.2,C.dbd.CHCl,C.dbd.CHCN,N--C.sub.1-4烷基,N-乙酰基,SO.sub.2和SO;X.sub.2...选自N.dbd.,CH.sub.2 --,CH.dbd.,C(O)--,O--和S--;Y选自N和CH;R.sub.1代表C.sub.1-4烷基;n为0、1或2;q为1或2;Z为C.sub.5-10烷基,可选择性地取代为OH、卤素、C.sub.1-4烷基或C.sub.1-4烷氧基,并可选择性地包含从O、N和S中选择的杂原子;以及其酸盐、溶剂化物和水合物。还描述了它们作为多巴胺受体配体用于鉴定和药物筛选计划,并作为治疗D4受体涉及的疾病,如精神分裂症的药物。
