The development of resistance against most of the available antibiotics has made () a pathogen of high risk. In this study, thirty novel berberine derivatives are rationally designed, synthesized, and evaluated for their synergistic antibacterial activities against . Among them, compound shows the most potent synergetic effect to aztreonam against , including carbapenem-resistant and extended-spectrum
对大多数可用抗生素产生耐药性已使 () 成为高风险病原体。在这项研究中,合理设计、合成了三十种新型小檗碱衍生物,并评估了它们对 的协同抗菌活性。其中,化合物与氨曲南对包括碳青霉烯类耐药菌株和产广谱内酰胺酶菌株表现出最有效的协同作用。此外,在临床实践中观察到不同抗菌药物的组合和使用的协同效应,表明其对 的有效广谱抗生素增敏作用。与单独使用氨曲南治疗相比,联合使用氨曲南可显着提高幼虫的存活率。机理研究表明,通过靶向AdeB转运蛋白,抑制细菌的药物外流和铁的获取,从而实现与不同抗菌药物的协同抗菌功效。因此,小檗碱衍生物代表了一类新的抗菌佐剂家族,具有双功能抗菌作用的优点,值得进一步研究。
