  Cefiderocol (S-649266), A new siderophore cephalosporin exhibiting potent activities against Pseudomonas aeruginosa and other gram-negative pathogens including multi-drug resistant bacteria: Structure activity relationship

  摘要：

  The structure-activity relationship (SAR) for a novel series of catechol conjugated siderophore cephalosporins is described with their in vitro activities against multi-drug resistant Gram-negative pathogens including Pseudomonas aeruginosa, Acinetobacter baumannii, Stenotrophomonas maltophilia and Enterobacteriaceae. Cefiderocol (3) was one of the best molecules which displayed well-balanced and potent activities against multi-drug resistant Gram-negative pathogens including carbapenem resistant bacteria among the prepared compounds with the modified C-7 side chain and the modified C-3 side chain. Cefiderocol (3) is a highly promising parenteral cephalosporin for the treatment of multi-drug resistant Gram-negative infection. (C) 2018 Elsevier Masson SAS. All rights reserved.

  YFJ-36 的发现：儿茶酚共轭 β-内酰胺的设计、合成及其对革兰氏阴性菌的抗菌活性

  摘要：

  头孢地可是第一个被批准的针对多重耐药革兰氏阴性菌的儿茶酚缀合头孢菌素，但其应用受到吡咯烷连接子化学稳定性差、对肺炎克雷伯菌和鲍曼不动杆菌效力中等、盐制备过程复杂以及潜在潜力的限制。超敏反应。为了解决这些问题，设计、合成和评估了一系列新型儿茶酚共轭衍生物。进行了广泛的结构-活性关系和结构-代谢关系（SMR），发现了具有新硫醚连接基的有前途的化合物86b （代码号YFJ-36）。与头孢地考相比， 86b表现出优异的广谱体外抗菌活性，尤其是针对鲍曼不动杆菌和肺炎克雷伯菌。在小鼠全身感染模型中观察到有效的体内功效。此外， 86b在 pH 6-8 的流体介质中的物理化学稳定性得到增强。由于季铵连接基， 86b还降低了潜在的过敏风险。 86b的改进性能支持了其进一步的研究和开发。
