ligand‐based approach, 3‐methoxyquinoxalin‐2‐carboxamides were designed as serotonin type‐3 (5‐HT3) receptor antagonists and synthesized from the starting material o‐phenylenediamine in a sequence of reactions. The structures of the synthesized compounds were confirmed by spectral data. These carboxamides were investigated for their 5‐HT3 receptor antagonisms in longitudinal muscle myenteric plexus preparations
采用基于配体的方法,3-甲氧基喹喔啉-2-甲酰胺被设计为5-羟色胺3型(5-HT3)受体拮抗剂,并由原料邻苯二胺在一系列反应中合成。合成化合物的结构由光谱数据证实。研究了这些羧酰胺在来自豚鼠回肠的纵向肌肉肌间神经丛制剂中对标准 5-HT3 激动剂 2-甲基-5-HT 的 5-HT3 受体拮抗作用,并将它们的拮抗活性表示为 pA2 值。化合物6a(pA2:7.2)、6e(pA2:7.0)、6f(pA2:7.5)、6g(pA2:7.5)、6n(pA2:7.0)和6o(pA2:7.2)表现出的拮抗作用大于标准 5-HT3 拮抗剂,昂丹司琼(pA2:6.9)。
