The invention relates to compounds of the general formula (I):
wherein
R' represents a group CO2R5, COR5, CONR5R6 or SO2R5 (wherein R5 and R6, which may be the same or different, each represents a hydrogen atom, a C1-6 alkyl or C3.7 cycloalkyl group, or a phenyl or phenyl- (C1-4) alkyl group in which the phenyl group is optionally substituted by one or more C1-4 alkyl, C1-4, alkoxy or hydroxy groups or halogen atoms, with the proviso that R5 does not represent a hydrogen atom when R' represents a group CO2R5 or SO2R5); and one of the groups represented by R2, R3 and R4 is a hydrogen atom or a C1-6 alkyl, C3-7 cycloalkyl, C2-6 alkenyl or phenyl-(C1-3)alkyl group and each of the other two groups, which may be the same or different, represents a hydrogen atom or a C1-6 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'代表基团 CO2R5、COR5、CONR5R6 或 SO2R5(其中 R5 和 R6 可以相同或不同,各自代表氢原子、C1-6 烷基或 C3.7环烷基,或苯基或苯基-(C1-4)烷基,其中苯基任选被一个或多个C1-4烷基、C1-4、烷氧基或羟基或卤素原子取代,但当R'代表CO2R5或SO2R5基团时,R5不代表氢原子);R2、R3 和 R4 所代表的基团之一是氢原子或 C1-6 烷基、C3-7 环烷基、C2-6 烯基或苯基-(C1-3)烷基,而另外两个基团(可以相同或不同)分别代表氢原子或 C1-6 烷基;及其生理上可接受的盐和溶剂。
这些化合物是 "神经元 "5-羟色胺受体的强效选择性拮抗剂,可用于治疗精神病(如精神分裂症和躁狂症)、焦虑、疼痛、胃淤血、胃肠功能紊乱症状(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。
