Oximes are known for their anti-inflammatory, antimicrobial, antioxidant, and anticancer activities. Frequently, modification of biologically active carbonyl compounds into oximes leads to increased activity. The present study reports the reactivity of 2-alkanoylnaphthohydroquinones against hydroxylamine under aerial conditions. Results show that, depending on the structure of the hydroquinones, the
肟以其抗炎、抗菌、抗氧化和抗癌活性而闻名。通常,将具有生物活性的羰基化合物修饰成肟会导致活性增加。本研究报告了 2-烷酰基萘氢醌在空气条件下对羟胺的反应性。结果表明,根据氢醌的结构,反应通过两种不同的化学途径进行,生成 2-(羟基氨基)-1,4-萘醌及其 C-3(羟基亚氨基)烷基衍生物。讨论了空气氧化下醌类化合物的形成和半胺中间体的 CC 裂解反应。在一组癌细胞上对取代的 1,4-萘醌进行体外筛选显示出中等的细胞毒活性。化合物19, 2-(hydroxyamino)-1,4-naphthoquinone 因其对前列腺癌细胞的抗癌效力而脱颖而出,如最低的 IC 50值 (8.08 μM ) 和最佳的选择性指数 (3.90) 所示。
