Sixteen analogues of fimbrolides (brominated 3-substituted-5-methylene-2(5H)-furanones), naturally occurring bacterial quorum sensing (QS) inhibitors, were synthesized by a novel sequence. The importance of the methylene group, either brominated or non-brominated, in LuxR-dependent QS inhibition was demonstrated. One of the most active furanone-type QS inhibitors was identified, with an IC50 of 0.6 μM.
通过一种新的合成序列,合成了十六种芬布罗类(溴化的3-取代-5-亚甲基-2(5H)-呋喃酮)类似物,这些化合物是天然存在的细菌群体感应(QS)抑制剂。实验证明了亚甲基团的重要性,无论是溴化的还是非溴化的,在LuxR依赖的QS抑制中。其中一种活性最强的呋喃酮型QS抑制剂被鉴定出来,其IC50值为0.6 μM。
