由难以治疗的耐甲氧西林金黄色葡萄球菌(MRSA)引起的感染是一个严重的全球公共卫生问题,因为MRSA已经对许多类别的抗生素产生了广泛的耐药性。我们在此公开了一类新的非β-内酰胺类抗生素--恶二唑的发现,它能抑制耐甲氧西林金黄色葡萄球菌的青霉素结合蛋白2a。恶二唑对万古霉素和利奈唑胺耐药的MRSA和其他革兰氏阳性细菌菌株显示出杀菌活性,在小鼠感染模型中具有体内疗效,并具有100%的口服生物利用度。
Infections caused by hard-to-treat methicillin-resistant Staphylococcus aureus (MRSA) are a serious global public-health concern, as MRSA has become broadly resistant to many classes of antibiotics. We disclose herein the discovery of a new class of non-β-lactam antibiotics, the oxadiazoles, which inhibit penicillin-binding protein 2a (PBP2a) of MRSA. The oxadiazoles show bactericidal activity against vancomycin- and linezolid-resistant MRSA and other Gram-positive bacterial strains, in vivo efficacy in a mouse model of infection, and have 100% oral bioavailability.
