We prepared a series of cinnamoyl-containing furanones by an affordable and short synthesis. The nineteen compounds hold a variety of substituents including electron-donating, electron-withdrawing, bulky and meta-substituted phenyls, as well as heterocyclic rings. Compounds showed antibiofilm activity in S. aureus, K. pneumoniae and, more pronounced, against P. aeruginosa. The disruption of quorum
我们通过经济且短的合成制备了一系列含肉桂酰基的呋喃酮。这十九种化合物含有多种取代基,包括给电子、吸电子、大体积和间位取代的苯基以及杂环。化合物对金黄色葡萄球菌、肺炎克雷伯菌以及更明显的铜绿假单胞菌表现出抗生物膜活性。使用紫罗兰素测试测试了群体感应 (QS) 的破坏,并且分子对接预测了 LasR 的拮抗作用作为一种合理的作用机制。三甲氧基化和二烯衍生物表现出最佳的抗生物膜和抗 QS 特性,因此成为进一步修饰的候选者。
