Development of the efficient method for the analysis and identification of the target proteins with which biologically active glycosides directly interact is highly desirable in many research fields. In this article, we report an efficient strategy for the preparation of chemical probes of biologically active glycosides using a reaction sequence of i) a boron-mediated aglycon delivery (BMAD) with an
在许多研究领域中,开发用于分析和鉴定与生物活性糖苷直接相互作用的靶蛋白的有效方法是非常需要的。在本文中,我们报告了一种有效的策略,用于制备生物活性糖苷的化学探针,其反应序列为 i) 硼介导的糖苷配基递送 (BMAD) 与 N 3 -功能化的 1,2-脱水葡萄糖供体,ii)去保护,和 iii) 应变促进的叠氮化物-炔烃环加成。使用合成的化学探针,我们成功地证明了强心苷的靶蛋白,毛花苷 C ( 1 ),可以在人类结肠癌 HCT116 细胞中进行可视化和鉴定。
