Use of biofilm dispersing NO-donor compounds in combination with antibiotics has emerged as a promising new strategy for treating drug-resistant bacterial biofilm infections. This paper details the synthesis and preliminary evaluation of six cephalosporin-3'-diazeniumdiolates as biofilm-targeted NO-donor prodrugs. Each of the compounds is shown to selectively release NO following reaction with the
生物膜分散NO供体化合物与抗生素的结合使用已成为治疗耐药细菌生物膜感染的有前途的新策略。本文详细介绍了六种头孢菌素3'-二氮杂二醇盐作为生物膜靶向NO供体前药的合成和初步评估。已显示每种化合物在与细菌特异性酶β-内酰胺酶反应后选择性释放NO,并在体外触发铜绿假单胞菌生物膜的分散。
