耐药细菌的出现鼓励我们开发新的抗生素和策略,以弥补它们获得的不同耐药机制。耐药细菌的防御机制之一是形成生物膜。在此,我们表明,具有各种柔性或刚性侧链的苯并咪唑鎓盐作为强抗生素和抗菌膜剂。我们表明,它们的生物膜活性是由于它们能够破坏生物膜基质和细菌细胞膜。这些化合物能够避免生物膜的形成并分散成熟的生物膜,显示出在生物膜相关感染的治疗中的普遍用途。苯并咪唑盐损害生物膜和细菌膜结构完整性。
Emergence of resistant bacteria encourages us to develop new antibiotics and strategies to compensate for the different mechanisms of resistance they acquire. One of the defense mechanisms of resistant bacteria is the formation of biofilms. Herein we show that benzimidazolium salts with various flexible or rigid side chains act as strong antibiotic and antibiofilm agents. We show that their antibiofilm activity is due to their capacity to destroy the biofilm matrix and the bacterial cellular membranes. These compounds are able to avoid the formation of biofilms and disperse mature biofilms showing a universal use in the treatment of biofilm-associated infections. Benzimidazolium salts impair biofilm and bacterial membrane structural integrity.
