The bacterial deacetylase LpxC is a promising target for the development of novel antibiotics being selectively active against Gram-negative bacteria. In chiral pool syntheses starting from d- and l-ribose, a series regio- and stereoisomeric monohydroxytetrahydrofuran derivatives was synthesized and tested for LpxC inhibitory and antibacterial activities. Molecular docking studies were performed to
细菌脱乙酰酶 LpxC 是开发对革兰氏阴性菌有选择性活性的新型抗生素的有希望的目标。在从d-和l-核糖开始的手性池合成中,合成了一系列区域和立体异构单羟基四氢呋喃衍生物并测试了 LpxC 抑制和抗菌活性。进行分子对接研究以合理化获得的结构 - 活性关系。(2 S ,3 R ,5 R )-构型的 3-羟基四氢呋喃衍生物ent- 8 ((2 S ,3 R ,5 R ) -N,3-Dihydroxy-5-(4-[4-(morpholinomethyl)phenyl]ethynyl}phenyl)tetrahydrofuran-2-carboxamide) 被发现是合成系列中最有效的 LpxC 抑制剂 (K i = 3.5 µM)一羟基四氢呋喃衍生物,对大肠杆菌BL21(DE3)和D22菌株表现出最高的抗菌活性。
