sulfonyl-hybridized imidazolyl ethanols as potential DNA-targeting antibacterial agents was constructed via the unique ring-opened reaction of oxiranes by imidazoles for the first time. Some developed target hybrids showed potential antimicrobial potency against the tested microbes. Especially, imidazole derivative 5f could strongly suppressed the growth of MRSA (MIC = 4 μg/mL), which was 2-fold and 16-fold more potent
一种新型磺酰杂交咪唑基乙醇作为潜在的DNA靶向抗菌剂的构建通过环氧乙烷的由咪唑首次独特的开环反应。一些开发的目标杂交体显示出对测试微生物的潜在抗菌效力。尤其是咪唑衍生物5f可以强烈抑制 MRSA 的生长(MIC = 4 μg/mL),其效力是阳性对照磺胺噻唑和诺氟沙星的 2 倍和 16 倍。该化合物表现出相当低的诱导细菌耐药性的倾向。抗菌机制探索表明化合物5f可以嵌入MRSA DNA中形成稳定的5f-DNA 复合物,可能阻碍 DNA 复制发挥抗菌作用。分子对接表明分子5f可以通过氢键与二氢叶酸合成酶结合。这些结果表明咪唑衍生物5f可以作为探索新型抗菌候选物的有前途的分子。
