In the past 20 years, peptide‐based antibiotics, such as vancomycin, teicoplanin, and daptomycin, have often been considered as second‐line antibiotics. However, in recent years, an increasing number of reports on vancomycin resistance in pathogens appeared, which forces researchers to find novel lead structures for potent new antibiotics. Herein, we report the total synthesis of a defined endo‐type B
在过去的20年中,基于肽的抗生素,例如万古霉素,替考拉宁和达托霉素,通常被认为是二线抗生素。然而,近年来,有关病原体对万古霉素耐药性的报道越来越多,这迫使研究人员为有效的新抗生素寻找新的先导结构。在此,我们报告了一个确定的内切型B PPAP文库的总合成及其对多重耐药金黄色葡萄球菌和各种对万古霉素耐药的肠球菌的抗生素活性。鉴定出了四个结合了高活性和低细胞毒性的新化合物,表明PPAP核心可能成为抗生素研究中一种新的非基于肽的前导结构。
