Abstract

Herein, we describe a reliable and efficient approach for the first chemical synthesis of biologically significant and complex 3--(-3-hydroxydecanoyl) modified uridine diphosphate -acetylglucosamine that is the native substrate of LpxC involved in the biosynthesis of the cell wall of . The synthetic protocol provides a successful example for the reliable preparation of modified nucleoside diphosphate sugar, which features judiciously selected protecting groups, the formation of pyrophosphate linkage with 5'-phosphate nucleoside as nucleophile, and the straightforward purification process.

摘要

在此,我们描述了一种可靠且高效的方法,用于首次化学合成具有生物学意义的复杂3-(-3-羟基癸酰基)修饰的尿苷二磷酸-N-乙酰葡糖胺,它是参与[具体生物]细胞壁生物合成的LpxC的天然底物。该合成方案为可靠制备修饰的核苷二磷酸糖提供了一个成功范例,其特点是精心选择了保护基团,以5'-磷酸核苷作为亲核试剂形成焦磷酸键,以及纯化过程简便直接。
