A structure-activity relationship (SAR) for the oxadiazole class of antibacterials was evaluated by syntheses of 72 analogs and determination of the minimal-inhibitory concentrations (MICs) against the ESKAPE panel of bacteria. Selected compounds were further evaluated for toxicity, plasma protein binding, pharmacokinetics (PK), and a mouse model of methicillin-resistant (MRSA) infection. Oxadiazole shows potent antibacterial activity, exhibits low clearance, a high volume of distribution, and 41% oral bioavailability, and shows efficacy in mouse models of MRSA infection.
通过合成72种类似物并测定对ESKAPE细菌组的最低抑菌浓度(MIC),评估了恶二唑类抗菌剂的构效关系(SAR)。对选定的化合物进一步评估其毒性、血浆蛋白结合率、药代动力学(PK)以及耐甲氧西林金黄色葡萄球菌(MRSA)感染的小鼠模型。恶二唑显示出强效抗菌活性,清除率低,分布容积高,口服生物利用度为41%,并在MRSA感染的小鼠模型中显示出疗效。
