microbes was synthesized by one-pot three-component reaction. Noticeably, fluorobenzyl derivative 5d (MIC = 2 μg/mL) was active against drug resistant E. coli infection and exerted no obvious toxicity towards human mammalian cells. Compound 5d also displayed good anti-biofilm activity and low possibility to induce drug resistance. Mechanism investigation elucidated that molecule 5d could disrupt E. coli

生物 5d (MIC = 2 μg/mL) 对耐药性大肠杆菌感染有活性,对人类哺乳动物细胞没有明显的毒性。化合物5d还表现出良好的抗
生物膜活性,诱导耐药性的可能性很小。机制研究阐明分子 5d 可以破坏大肠杆菌膜通过产生活性氧 (ROS) 然后嵌入
脱氧核糖核酸 (DNA) 形成稳定的 5d-DNA 复合物,从而导致细菌死亡。这些结果表明
磺胺氨基膦酸盐将有助于开发新的潜在抗菌剂。
