Zidebactam (WCK 5107) 是一种新型β-内酰胺增强剂 (BLE),由 Wockhardt 开发,对多种革兰氏阴性病原体表现出独立的抗菌活性。齐德巴坦被称为β-内酰胺“增强剂”,因为与伙伴β-内酰胺药物联合使用时,齐德巴坦不仅可以抑制β-内酰胺酶,还可以靶向PBP2并增强伙伴药物的效力。该手稿详细介绍了Zidebactam的立体选择性合成,以及制备稳定的(2S,5R)-6-benzyloxy-7-oxo-1,6-diaza-bicyclo[3.2.1]钠盐的技术/工艺。 ]-辛烷-2-甲酸和手性纯侧链,N -Boc-( R )-(-)-哌啶甲酸乙酯通过手性拆分得到。通过DBO羧酸的钠盐与Boc-( R )-(-)-乙基哌啶酰肼的偶联,然后进行必要的化学转化,实现了齐达巴坦的聚合合成。单晶X射线分析建立了齐德巴坦的立体化学,经验式为C 13 H 21 N 5 O 7 S.2H

extended spectrum β-lactamase inhibitor (ESBLI). It’s combination with cefepime (WCK 5222) is in phase III clinical studies. Five process impurities were found in zidebactam (1) drug substance using process development through reverse phase high performance liquid chromatography (HPLC) method. To give access to the reference standards for the impurity profile of the drug substance as well as the final product
