Novel antibiotics are forced to be developed on account of multidrug-resistant bacteria with serious threats to human health. This work developed isatin-derived azoles as new potential antimicrobial agents. Bioactive assay revealed that isatin hybridized 1,2,4-triazole 7a exhibited excellent inhibitory activity against E. coli ATCC 25,922 with an MIC value of 1 µg/mL, which was 8-fold more potent than
由于多重耐药菌严重威胁人类健康,因此被迫开发新型抗生素。这项工作开发了靛红衍生的唑类作为新的潜在抗菌剂。生物活性测定表明,靛红杂交的 1,2,4-三唑7a对大肠杆菌ATCC 25,922表现出优异的抑制活性,MIC 值为 1 µg/mL,其效力是参考药物诺氟沙星的 8 倍。活性分子7a具有杀死一些细菌和真菌的能力,并且显示出诱导对大肠杆菌ATCC25922抗性的低倾向。初步机理研究表明,杂化7a 可能通过插入 DNA 并可能与 DNA 聚合酶 III 相互作用来阻止脱氧核糖核酸 (DNA) 复制,从而发挥其抗菌效力。
