Infection by Helicobacter pylori increases 10 times the risk of developing gastric cancer. Juglone, a natural occurring 1,4-naphthoquinone, prevents H. pylori growth by interfering with some of its critical metabolic pathways. Here, we report the design, synthesis, and in vitro evaluation of a series of juglone derivatives, namely, 2/3-phenylaminojuglones, as potential H. pylori growth inhibitors. Results
幽门螺杆菌感染会使患胃癌的风险增加10倍。Juglone是一种天然存在的1,4-萘醌,可通过干扰幽门螺杆菌的某些关键代谢途径来阻止幽门螺杆菌的生长。在这里,我们报告设计,合成和体外评估一系列juglone衍生物,即2 / 3-苯基氨基juglones,作为潜在的幽门螺杆菌生长抑制剂。结果表明,5超过了12 phenylaminojuglones(在1.5 μ克/毫升)是1.5-2.2倍胡桃醌更活跃。有趣的是,大多数苯氨基聚醚(12个中的10个)的活性是甲硝唑(一种已知的幽门螺杆菌)的1.1-2.8倍。生长抑制剂。活性最高的化合物2-(((3,4,5-三甲氧基苯基)氨基)-5-羟基萘-1,4-二酮7]的生长抑制晕环(HGI = 32.25 mm)明显高于juglone和甲硝唑(HGI = 14.50和11.67 mm)。该系列的结构活性关系表明,Juglone支架中氮取代基的性质和位置可能
