Just say NO to biofilms: NO‐donors are used to disperse a bacterial biofilm so that co‐administered antibiotics will kill the more susceptible unattached cells. The chemically stable cephalosporin‐3′‐diazeniumdiolate NO‐donor prodrug (see scheme) is activated by bacterial β‐lactamases and facilitates this two‐step biofilm erradication.
只需对生物膜说不:NO 供体用于分散细菌生物膜,这样共同施用的抗生素将杀死更敏感的未附着细胞。化学稳定的头孢菌素-3'-二氮烯二醇NO-供体前药(见方案)被细菌β-内酰胺酶激活并促进这种两步生物膜的根除。
