part of a search for a substrate for droplet-based microfluidic screening assay of α-N-acetylgalactosaminidases, spectral and physical characteristics of a series of coumarin derivatives were measured. From among these a new coumarin-based fluorophore, Jericho Blue, was selected as having optimal characteristics for our screen. A reliable method for the challenging synthesis of coumarin glycosides
为了寻找用于基于液滴的α- N-乙酰半乳糖苷酶微滴筛选分析底物的一部分,对一系列香豆素衍生物的光谱和物理特性进行了测量。从这些新的基于香豆素的荧光团中,我们选择了具有最佳特性的Jericho Blue。然后开发了一种可靠的方法,用于挑战性合成α-GalNAc香豆素苷,并通过9个实例进行了证明。以这种方式制备的耶利哥蓝的α-GalNAc糖苷在筛选条件下显示出良好的功能。
