inflammatory allergic reactions by blocking histamine release and pro-inflammatory cytokine expression. In this report, various amide analogs of gallic acid have been synthesized by introducing different amines through carbodiimide-mediated amide coupling and Pd/C-catalyzed hydrogenation. These compounds showed a modest to high inhibitory effect on histamine release and pro-inflammatory cytokine expression
没食子酸(3,4,5-三羟基苯甲酸)是一种天然产物,存在于各种食物和草药中,是众所周知的强效抗氧化剂。我们之前的报告表明,它通过阻断组胺释放和促炎细胞因子表达来抑制肥大细胞衍生的炎症过敏反应。在本报告中,通过碳二亚胺介导的酰胺偶联和 Pd/C 催化的氢化引入不同的胺,合成了各种没食子酸的酰胺类似物。这些化合物对组胺释放和促炎细胞因子表达表现出中等至高度的抑制作用。其中,带有酰胺的 (S)-苯基甘氨酸甲酯 3d 被发现比天然没食子酸更具活性。进一步优化产生了几种在体外抑制组胺释放的 (S)-和 (R)-苯基甘氨酸类似物。
