    • 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; andZ 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.
    • 本文描述的是具有以下通式的D4受体选择性化合物:其中:A和B独立选择,任选取代的饱和或不饱和的5-或6-元,杂环或杂环; X 1选自CH 2,O,NH,S,C = O,CH-OH,CH-N(C 1-4烷基)2,C = CHCl,C = CHCN,N-C 1-4烷基,N-乙酰基, 所以; X2。 。 。 选自N =,CH 2 - ,CH =,C(O) - ,O-和S-; Y选自N和CH; R 1表示C 1-4烷基; n为0,1或2; q为1或2; 并且Z是任选地被OH,卤素,C 1-4烷基或C 1-4烷氧基取代并任选地引入选自O,N和S的杂原子的C 5-10-10烷基; 及其酸加成盐,溶剂化物和水合物。 还描述了它们作为多巴胺受体鉴定和药物筛选程序的配体的用途,以及用于治疗其中涉及D4受体的适应症的药物,例如精神分裂症。
