for anti-inflammatory drug development. In this study, several new 3-acetyl-7-hydroxycoumarin derivatives were designed, synthesized and tested as anti-inflammatory agents. Interestingly, Mannich bases and Betti bases were separately obtained under acidic or neutral conditions. The regioselectivity of aminomethylation was studied based on the atomic electron density distribution by analysing the Voronoi
7-羟基
香豆素是抗发炎药物开发的优先结构。在这项研究中,设计,合成和测试了几种新的3-乙酰基-7-羟基
香豆素衍
生物作为抗炎药。有趣的是,曼尼希碱和贝蒂碱是在酸性或中性条件下分别获得的。通过分析Voronoi变形密度(VDD)原子电荷,基于原子电子密度分布研究了
氨基甲基化的区域选择性,这可以合理地解释实验结果。对
一氧化氮(NO)和肿瘤坏死因子α(TNF-α)释放的检测表明,曼尼希碱比相应的贝蒂碱具有更强的抗炎活性。
