The invention relates to compounds of the general formula (I): ##STR1## wherein R.sup.1 represents a group CO.sub.2 R.sup.5, COR.sup.5, CONR.sup.5 R.sup.6 or SO.sub.2 R.sup.5 (wherein R.sup.5 and R.sup.6, which may be the same or different, each represents a hydrogen atom, a C.sub.1-6 alkyl or C.sub.3-7 cycloalkyl group, or a phenyl or phenyl-(C.sub.1-4)alkyl group in which the phenyl group is optionally substituted by one or more C.sub.1-4 alkyl, C.sub.1-4 alkoxy or hydroxy groups or halogen atoms, with the proviso that R.sup.5 does not represent a hydrogen atom when R.sup.1 represents a group CO.sub.2 R.sup.5 or SO.sub.2 R.sup.5); and one of the groups represented by R.sup.2, R.sup.3 and R.sup.4 is a hydrogen atom or a C.sub.1-6 alkyl, C.sub.3-7 cycloalkyl, C.sub.2-6 alkenyl or phenyl-(C.sub.1-3)alkyl group and each of the other two groups, which may be the same or different, represents a hydrogen atom or a C.sub.1-6 alkyl group; and physiologically acceptable salts and solvates thereof. The compounds are potent and selective antagonists of "neuronal" 5-hydroxytryptamine receptors and are useful in the treatment of psychotic disorders (e.g. schizophrenia and mania); anxiety; pain; gastric stasis; symptoms of gastrointestinal dysfunction such as occur with dyspepsia, peptic ulcer, reflux oesophagitis and flatulence; migraine; and nausea and vomiting.
本发明涉及通式(I)的化合物:其中R.sup.1代表CO.sub.2 R.sup.5、COR.sup.5、CONR.sup.5 R.sup.6或SO.sub.2 R.sup.5(其中R.sup.5和R.sup.6,可以相同也可以不同,分别代表氢原子、C.sub.1-6烷基或C.sub.3-7环烷基,或苯基或苯基-(C.sub.1-4)烷基,其中苯基可能通过一个或多个C.sub.1-4烷基、C.sub.1-4烷氧基或羟基或卤素原子取代,但R.sup.5不代表氢原子时,R.sup.1代表CO.sub.2 R.sup.5或SO.sub.2 R.sup.5的群);以及由R.sup.2、R.sup.3和R.sup.4代表的群中的一个是氢原子或C.sub.1-6烷基、C.sub.3-7环烷基、C.sub.2-6烯丙基或苯基-(C.sub.1-3)烷基,另外两个群中的每一个,可以相同也可以不同,代表氢原子或C.sub.1-6烷基群;以及其生理上可接受的盐和溶剂化物。这些化合物是"神经元"5-羟色胺受体的有效和选择性拮抗剂,可用于治疗精神分裂症(如精神分裂症和狂躁症);焦虑;疼痛;胃瘫;胃肠功能障碍的症状,如消化不良、消化性溃疡、反流性食管炎和胀气;偏头痛;以及恶心和呕吐。
