the effect of these compounds from concentrations of 1 to 100 µM. Significant reduction in biofilm formation was achieved by 3-hexylylquinoxalin-2(1H)-one (11), 3-hexylylquinoxalin-2(1H)-one-6-carboxylic acid (12), and 3-heptylylquinoxalin-2(1H)-one-6-carboxylic acid (14), ranging from 11% to 59% inhibition of the biofilm. This pilot study contributes to the development of anti-QS compounds to overcome
随着细菌菌株对抗生素的耐药性的提高,迫切需要用于控制感染的替代方法。群体感应(QS)是一种基于小分子的细菌通讯系统。QS使细菌生物膜形成和致病性发展。中断QS已成为发现药物的目标,但仍处于实验的早期阶段。在这项研究中,我们合成了一套基于脚手架(烷基喹喔啉-2(1H)-一种)的六种化合物,这是革兰氏阴性caviae Sch3菌的抗QS新特性。通过量化生物膜形成,我们能够从1到100 µM的浓度监测这些化合物的作用。3-己基喹喔啉-2(1H)-一(11),3-己基喹喔啉-2(1H)-6-羧酸(12)可显着减少生物膜形成。和3-庚基喹喔啉-2(1H)-一-6-羧酸(14),对生物膜的抑制作用为11%至59%。这项初步研究有助于开发抗QS化合物,以克服耐药菌菌株的临床挑战。
