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
制备了在胺部分具有六氢-1,4-二氮杂或六氢氮杂pine环的一系列新型苯甲酰胺,并评估了它们对5-HT3和多巴胺D2受体的结合亲和力。1-乙基-4-甲基六氢-1,4-二氮杂吡啶基苯甲酰胺(R)-22的R异构体对两种受体均具有强大的亲和力。相应的1-乙基六氢氮杂吡啶基苯甲酰胺28的R-对映异构体显示出对多巴胺D2受体的有效亲和力,而对5-HT3受体的亲和力降低,而S异构体是有效且选择性的5-HT3受体拮抗剂。
