Proteins of methicillin-resistant Staphylococcus aureus (MRSA), an antibiotic sensor/signal transducer, are phosphorylated on exposure to β-lactam antibiotics. This event is critical for the onset of the biochemical events that unleash induction of antibiotic resistance. The phosphorylation and the antibiotic-resistance phenotype can be abrogated in the presence of inhibitors described herein that restore susceptibility of the organism to β- lactam antibiotics. The invention thus provides compounds and methods for abrogating antibiotic resistance to β-lactam antibiotics and for treating infections causes by antibiotics prone to developing resistance by potentiating β-lactam antibiotics.

甲氧西林金黄色葡萄球菌(MRSA)的蛋白质是一种抗生素感应器/信号传导体,在暴露于β-内酰胺类抗生素时会发生
磷酸化。这一事件对于引发
生物化学事件的开始至关重要,从而诱导抗生素抗性。在本文所述的
抑制剂存在的情况下,
磷酸化和抗生素抗性表型可以被废除,从而恢复该
生物对β-内酰胺类抗生素的敏感性。因此,该发明提供了化合物和方法,用于废除对β-内酰胺类抗生素的抗性,并通过增强β-内酰胺类抗生素来治疗由易于产生抗性的抗生素引起的感染。
