wounds and live as biofilm, which causes antibiotic resistance and wounds unhealed. To investigate the effects of 5‐substituted 3,4‐dihalo‐5H‐furan‐2‐one compounds on biofilm formation of P. aeruginosa, a set of 5‐(aryl‐1′‐hydroxy‐methyl)‐ or 5‐(aryl‐2‐methylene)‐3,4‐dihalo‐5H‐furan‐2‐one compounds were designed and synthesized. Their inhibitory activities on biofilm formation of P. aeruginosa were studied
铜绿假单胞菌(P.aeruginosa)会在大多数伤口上定居并以生物膜的形式生活,这会导致抗生素耐药性并使伤口无法愈合。为了研究5-取代的3,4-二卤代5 H-呋喃2-1化合物对铜绿假单胞菌生物膜形成的影响,铜绿假单胞菌是一组5-(芳基1′-羟甲基)或5-设计并合成了(芳基-2-亚甲基)-3,4-二卤代-5 H-呋喃-2-酮化合物。通过MIC分析,生物膜抑制作用的定量分析和SEM观察生物膜形成对铜绿假单胞菌生物膜形成的抑制活性进行了研究。发现化合物2i,3f,3i铜绿假单胞菌对铜绿假单胞菌具有明显的生物膜形成抑制作用。此外,进行分子对接以鉴定这些化合物具有LasR受体结合位点的关键结构特征。
