The emergence of multidrug resistant (MDR) Gram-negative bacterial pathogens has raised global concern. Nontraditional therapeutic strategies, including antivirulence approaches, are gaining traction as a means of applying less selective pressure for resistance in vivo. Here, we show that rigidifying the structure of the siderophore preacinetobactin from MDR Acinetobacter baumannii via oxidation of the phenolate-oxazoline moiety to a phenolate-oxazole results in a potent inhibitor of siderophore transport and imparts a bacteriostatic effect at low micromolar concentrations under infection-like conditions.

刚性恶唑不动杆菌素类似物阻止鲍曼不动杆菌中铁载体的循环。

多药耐药(MDR)革兰氏阴性细菌病原体的出现引起了全球关注。非传统的治疗策略,包括抗病毒方法,正逐渐受到人们的关注,这是一种为体内抗药性施加较小选择性压力的方法。在这里,我们表明,通过将酚盐-恶唑啉部分氧化为酚盐-恶唑,使耐多药鲍曼不动杆菌中的铁载体前葡萄球菌素的结构刚性化,将产生有效的铁载体抑制剂,并在类似感染的低微摩尔浓度下产生抑菌作用。条件。
