Boronic acids that change fluorescent properties upon sugar binding are very important reporter units for the development of small molecule lectin mimics (boronolectins). Aimed at developing long wavelength fluorescent boronic acid reporter compounds, we have designed and synthesized a series of boronic acid analogs 2a-d with an extended pi conjugation. Such designs are based on earlier fluorescent
在糖结合时改变荧光特性的硼酸是开发小分子凝集素模拟物(硼凝集素)的非常重要的报告单位。为了开发长波长荧光硼酸报告化合物,我们设计并合成了一系列具有扩展 pi 共轭的硼酸类似物 2a-d。此类设计基于较早的荧光硼酸,其在糖结合时会改变荧光特性。与相应的母体生色团相比,这些具有扩展共轭的新化合物显示出更长的激发和发射波长。新化合物的荧光变化模式也与相应的母体化合物不同。
