The invention relates to compounds of the general formula(l):
wherein
R' represents a hydrogen atom or a C1-10 alkyl, C3-7 Ikyl, C3-7cycloalkyl-(C1-4)-alkyl, C3-6 alkenyl, C3-10 alkynyl, phenyl or phenyl-(C1-3)alkyl group;
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 C1-6alkyl group; and X represents a halogen atom or a hydroxy, C1-4 alkoxy, phenyl-(C1-3-alkoxy or C1-6 alkyl group or a group NR6R8 or CONR6R8 wherein R5 and R6, which may be the same or different, each represents a hydrogen atom or a C1-6, alkyl or C3-4 alkenyl group, or together with the nitrogen atom to which they are attached form a saturated 5 to 7 membered ring; 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(l)的化合物:
其中
R'代表氢原子或C1-10烷基、C3-7烷基、C3-7环烷基-(C1-4)-烷基、C3-6烯基、C3-10炔基、苯基或苯基-(C1-3)烷基;
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,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;X代表卤素原子或羟基、C1-4-烷氧基、苯基-(C1-3-烷氧基或 C1-6 烷基或基团 NR6R8 或 CONR6R8,其中 R5 和 R6 可以相同或不同,各自代表氢原子或 C1-6、烷基或 C3-4 烯基,或与所连接的氮原子一起形成饱和的 5-7 分子环;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。
