strategy to fight antibiotic resistance, two-component systems (TCSs) have emerged as novel targets. Among TCSs, master virulence regulators that control the expression of multiple virulencefactors are considered as excellent antivirulence targets. In Staphylococcus aureus, virulencefactor expression is tightly regulated by a few master regulators, including the SaeRS TCS. In this study, we used a SaeRS
作为对抗抗生素耐药性的替代策略,两组分系统(TCS)已成为新的靶标。在TCS中,控制多种毒力因子表达的主要毒力调节剂被认为是出色的抗毒目标。在金黄色葡萄球菌中,毒力因子的表达受到包括SaeRS TCS在内的一些主要调控因子的严格调控。在这项研究中,我们使用了SaeRS GFP-reporter系统筛选SaeRS的天然化合物抑制剂,并将当归keiskei的异戊烯化查尔酮xanthoangelol B 1确定为热门产品。我们已经合成了1及其衍生物PM-56,并显示1和PM-56都具有对SaeRS TCS的优异抑制能力,如各种体外和体内实验所证明的。作为一种行动方式
