against non‐replicating bacteria (for example, bacteria within biofilms). We report a series of halogenated phenazines (HP), inspired by marine antibiotic 1, that targets persistent bacteria. HP 14 demonstrated the most potent biofilm eradication activities to date against MRSA, MRSE, and VRE biofilms (MBEC=0.2–12.5 μM), as well as the effective killing of MRSA persister cells in non‐biofilm cultures
常规抗生素对非复制性细菌(例如生物膜内的细菌)无效。我们报告了一系列受海洋抗生素1启发的卤化吩嗪(HP),其针对持久性细菌。HP 14展示了迄今为止针对MRSA,MRSE和VRE生物膜(MBEC = 0.2–12.5μM)的最有效的生物膜根除活动,以及在非生物膜培养物中可有效杀死MRSA持久性细胞。一线治疗MRSA,万古霉素和达托霉素,无法根除MRSA生物膜或非生物膜,持久旁边14。HP 13显示强抗菌活性对生长缓慢的分枝 杆菌(MIC = 3.13μM),这是全球细菌感染致死的主要原因。HP类似物通过对哺乳动物细胞无毒的机制有效靶向持久性细菌,并且可能对慢性细菌感染的治疗产生重大影响。
