A series of quinoxalin-2-carboxamides were designed as per the pharmacophoric requirements of 5-HT(3) receptor antagonists and synthesized by condensing the carboxylic group of quinoxalin-2-carboxylic acid with various amines in the presence of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and 1-hydroxybenzotriazole. The structures of the synthesized compounds were confirmed by physical
根据5-HT(3)受体拮抗剂的药效学要求设计了一系列喹喔啉-2-羧酰胺,并通过在1-(3-)存在下将喹喔啉-2-羧酸的羧基与各种胺缩合来合成二甲基氨基丙基)-3-乙基碳二亚胺盐酸盐和1-羟基苯并三唑。通过物理和光谱数据证实了合成化合物的结构。从豚鼠回肠针对5-HT(3)激动剂2-methy-5-HT的纵向肌肉-肠系膜神经丛制剂中评估了羧酰胺对5-HT(3)受体的拮抗作用。所有合成的化合物均显示5-HT(3)受体拮抗作用,(4-苄基哌嗪-1-基)(喹喔啉-2-基)甲酮是该系列中最有效的化合物。
