A series of novel 3-substituted quinoxalin-2-carboxamides were designed as per the pharmacophoric requirement for 5-HT(3) receptor antagonists and prepared by microwave irradiation and also by conventional method. The compounds were characterized by spectral data (IR, (1)H NMR, and MS) and the purity was ascertained by microanalysis. The synthesized compounds were evaluated for 5-HT(3) antagonisms
根据药效学要求,对5-HT(3)受体拮抗剂设计了一系列新型的3-取代的喹喔啉-2-羧酰胺,并通过微波辐射和常规方法制备。通过光谱数据(IR,(1)H NMR和MS)表征化合物,并通过微量分析确定纯度。评价了合成的化合物对5-HT(3)激动剂2-甲基-5-HT的豚鼠回肠纵向肌肉-肠系膜丛制备中的5-HT(3)拮抗作用。在测试化合物中,N- 3-[(4-甲基哌嗪-1-基)甲基] -4-羟基苯基} -3-甲氧基喹喔啉-2-碳氧酰胺4e显示出最有利的5-HT(3)受体拮抗作用。
