MRSA and VRE strains in addition to potent MRSE biofilm eradication activities (MBEC = 2.35 μM). Several of the halogenated quinolines identified here reported low cytotoxicity against HeLa cells with minimal hemolytic activity against red blood cells. We believe that halogenated quinoline small molecules could play an important role in the development of next-generation antibacterial therapeutics capable
抗抗生素细菌和表面附着的生物膜继续在人类健康和疾病中发挥重要作用。需要创新的策略来确定新的治疗方法,以解决耐药和耐性细菌的感染。我们合成了14个新的卤代喹啉的聚焦库,以研究ClogP值对抗菌和生物膜清除活性的影响。在这些研究过程中,我们发现在HQ支架的2位选择的极耳比其他人具有更好的耐受性。我们很高兴看到多种化合物显示出对主要人类病原体表皮葡萄球菌的增强活性。特别是总部2(ClogP = 3.44)与有效的MRSE生物膜根除活性(MBEC = 2.35μM)相比,与MRSA和VRE菌株相比,对MRSE 35984浮游细胞(MIC = 0.59μM)表现出增强的活性。本文鉴定的几种卤代喹啉对HeLa细胞的细胞毒性低,对红细胞的溶血活性极低。我们认为,卤代喹啉小分子在下一代靶向和消除生物膜相关感染的抗菌药物的开发中可以发挥重要作用。
