Abstract A novel series of quinoline-containing fused heterocyclic compounds with a 1,2,4-triazolo[3,4-b][1,3,4]thiadiazine core were designed and synthesised. The newly synthesized derivatives were characterized by FTIR, 1H and 13C NMR, and ESI mass spectra. All compounds exhibited excellent activities against Gram-negative and Gram-positive bacteria (MIC < 4.5 μg/mL), and some of the compounds were
摘要 设计并合成了一系列以 1,2,4-三唑并[3,4- b ][1,3,4]噻二嗪为核心的含喹啉稠合杂环化合物。新合成的衍生物通过 FTIR、1 H 和13 C NMR 以及 ESI 质谱进行了表征。所有化合物均对革兰氏阴性菌和革兰氏阳性菌表现出优异的活性(MIC < 4.5 μg/mL),部分化合物对金黄色葡萄球菌和大肠杆菌具有活性,MIC 值在 5.10 至 6.10 μg/mL 之间毫升。计算分子对接研究显示在 –7.34 至 –8.10 kcal/mol 范围内具有良好的结合分数,并且预测四种化合物对细菌 DNA 促旋酶 (2XCT) 显示出显着的亲和力。
