The present invention provides a fluorescent amino acid derivative which can be synthesized by simple steps, can be excited particularly by a blue laser ray region of visible light, and has an improved light stability. These objects can be achieved by a fluorescent amino acid derivative which is an acridone derivative substituted with an amino acid to comprise an electrophilic substituent group between the amino acid and the acridone derivative. Instead of a conventional strategy that aminophenylalanine is used as a starting material to form a fluorescent group through a coupling reaction and an intramolecular cyclization reaction, a fluorescent acridone derivative is used as a starting material to furnish the material to a reactive group by a position-specific electrophilic substitution reaction, and then the acridone derivative having the reactive group is allowed to couple with an amino acid derivative.
本发明提供了一种荧光氨基酸衍生物,可以通过简单的步骤合成,特别能够被可见光的蓝色激光区域激发,并具有改善的光稳定性。这些目标可以通过一种荧光氨基酸衍生物实现,该衍生物是一种取代了氨基酸的蒽醌衍生物,包含在氨基酸和蒽醌衍生物之间的亲电取代基团。与传统策略不同,传统策略是使用氨基苯丙氨酸作为起始材料,通过偶联反应和分子内环化反应形成荧光基团,本发明使用荧光蒽醌衍生物作为起始材料,通过位置特异性亲电取代反应将材料提供给反应基团,然后将具有反应基团的蒽醌衍生物与氨基酸衍生物偶联。
