inhibitor, was identified as circumventing the β-lactam drug resistance in methicillin-resistant Staphylococcus aureus (MRSA). We describe the concise total syntheses of a series of natural products, which enabled determination of the absolute configuration of fusarilactone A and provided structure-activity relationship information. Based on previous reports, we speculated that the target protein of this
Hymeglusin 是一种先前已知的真核羟甲基戊二酰
辅酶 A (
HMG−CoA) 合酶
抑制剂,被认为可以规避耐
甲氧西林金黄色葡萄球菌(MRSA) 中的 β-内酰胺耐药性。我们描述了一系列
天然产物的简明全合成,从而能够确定镰刀菌内酯A的绝对构型并提供构效关系信息。根据之前的报道,我们推测这种规避作用的靶蛋白可能是MRSA细菌
HMG−CoA合酶(mvaS)。我们发现这种酶受到hymeglusin剂量依赖性抑制。此外,MRSA mvaS
基因的过度表达和定点诱变研究表明了其结合位点和作用机制。
