AmpC beta-lactamase confers resistance to beta-lactam antibiotics in many Gram negative bacteria. Inducible expression of AmpC requires an N-acetylglucosaminidase termed NagZ. Here we describe the synthesis and characterization of hydroxyazepane inhibitors of NagZ. We find that these inhibitors enhance the susceptibility of clinically relevant Pseudomonas aeruginosa to beta-lactams.
AmpCβ-内酰胺酶赋予许多革兰氏阴性细菌对β-内酰胺抗生素的抗性。AmpC的诱导表达需要一个称为NagZ的N-乙酰氨基葡糖苷酶。在这里,我们描述了NagZ的羟基氮杂环庚烷抑制剂的合成和表征。我们发现这些抑制剂增强了临床相关的铜绿假单胞菌对β-内酰胺的敏感性。
