Antimicrobial peptides (AMPs) are a key component of the human immune system. Synthetic AMP mimics represent a novel strategy to counteract the increasing incidence of antimicrobial resistance. Here, we describe the synthesis of novel glyoxamide derivatives via ring-opening reactions of N-hexanoyl, N-benzoyl and N-naphthoylisatins with N,N-dimethylethane-1,2-diamine and N,N-dimethylpropane-1,3-diamine
抗菌肽(AMPs)是人类免疫系统的关键组成部分。合成的AMP模拟物代表了一种新的策略来抵消抗菌素耐药性的增加。在这里,我们描述了通过N-己酰基,N-苯甲酰基和N-萘甲芥子素与N,N-二甲基乙烷-1,2-二胺和N,N-二甲基丙烷-1,3-的开环反应合成新型乙二酰胺衍生物的方法。二胺。这些都转化为盐酸(HCl)或碘化季铵盐(MeI)盐,并且它们均对金黄色葡萄球菌具有抗菌活性。通过其抑制区和最小抑制浓度(MIC)进行了研究。HCl盐22b表现出最低的MIC,为16μgmL -1,而相应的MeI盐22c具有的MIC为39μgmL -1。我们还研究了活性化合物对MRC-5正常人肺成纤维细胞的体外毒性及其对金黄色葡萄球菌已建立的生物膜的活性。
