this context, the synthesis of readily functionalizable phosphonium-tagged coumarin derivatives enabling a dual mass-tag and fluorescence labelling of analytes or (bio)molecules of interest through a single-step protocol, is reported. The utility of these coumarins is illustrated through the preparation of fluorogenic substrates that facilitated identification of the peptide fragment released by specific
荧光香豆素是一类重要的小分子有机荧光团,在不同的成熟和新兴研究领域中普遍存在,其中包括生物化学和化学生物学。目前的工作旨在通过质谱法研究基于香豆素的结合物的可检测性差,同时保持香豆素核心的重要光物理性质。在这种情况下,已经报道了易于功能化的带有-标记的香豆素衍生物的合成,该合成的香豆素衍生物能够通过一步操作对目标分析物或(生物)分子进行双重质量标记和荧光标记。这些香豆素的用途通过荧光底物的制备来说明,该底物有助于鉴定由特异性蛋白水解裂解释放的肽片段。
