  Synthesis and neuroleptic activity of benzamides. cis-N-(1-Benzyl-2-methylpyrrolidin-3-yl)-5-chloro-2-methoxy-4-(methylamino)benzamide and related compounds

  摘要：

  Three series of benzamides of N,N-disubstituted ethylenediamines (linear alkane-1,2-diamines), 1-substituted 2-(aminomethyl)pyrrolidines, and 1-substituted 3-aminopyrrolidines (cyclic alkane-1,2-diamines) were designed and synthesized as potential neuroleptics. All target compounds were evaluated for their inhibitory effects on apomorphine-induced stereotyped behavior in rats, and a good correlation between structure and activity was found throughout the series. In the linear series (analogues of metoclopramide), introduction of a benzyl group on the terminal nitrogen, rather than an ethyl group, and a methyl group on the p-amino group of metoclopramide both enhanced the activity. The resulting N-[2-(N-benzyl-N-methylamino)ethyl]-5-chloro-2-methoxy-4-(methylamino) benzamide(23) was about 15 times more active than metoclopramide. In the cyclic series, particularly among the benzamides of 1-benzyl-3-aminopyrrolidine, most of the compounds tested were more active than the corresponding linear benzamides. cis-N-(1-Benzyl-2-methylpyrrolidin-3-yl)-5-chloro-2-methoxy-4-(methylamino) benzamide (YM-09151-2, 55) was the most active among all of the compounds tested, being 13 and 408 times more potent than haloperidol and metoclopramide, respectively. Moreover, compound 55 exhibited a fairly high ratio of antistereotypic activity to cataleptogenicity compared with haloperidol and metoclopramide. It is expected that compound 55 may be used as a potent drug with few side effects in the treatment of psychosis.

  摘要：

  为了寻找作为潜在的广泛止吐药的多巴胺D2和5-羟色胺5-HT3受体双重拮抗剂，从4-氨基-5-氯-2-甲氧基苯甲酸衍生物和6-氨基-1,4-制备了许多苯甲酰胺。分别使用大鼠脑突触膜和大鼠皮质膜评估二烷基六氢-1,4-二氮杂卓对多巴胺D2和5-羟色胺5-HT3受体的结合亲和力。从多巴胺D2受体的体外受体结合和体内生物学分析结果中，选择1-乙基-4-甲基六氢-1,4-二氮杂环作为最佳胺部分。在氮原子上的4-氨基-5-氯-2-甲氧基苯甲酰基基团的4-位引入一个甲基和/或在5-位取代基的修饰引起多巴胺D2受体结合的显着增加亲和力以及有效的5-HT3受体结合亲和力。在这些化合物中，5-氯-N-（1-乙基-4-甲基六氢-1,4-二氮杂-6-基）-2-甲氧基-4-甲基氨基苯甲酰胺（82），5-溴（110）和5 -碘（112）类似物对多巴胺D2受体的亲和力比对甲氧氯普胺的亲和力要高得多（IC50 = 17

  A novel series of benzamides with a hexahydro-1,4-diazepine or hexahydroazepine ring in the amine moiety were prepared, and their binding affinities for 5-HT3 and dopamine D2 receptors were evaluated. The R isomer of the 1-ethyl-4-methylhexahydro-1,4-diazepinylbenzamide (R)-22 had potent affinity for both receptors. The R-enantiomer of the corresponding 1-ethylhexahydroazepinylbenzamide 28 showed potent
