    • The subject of the present invention is to provide a fluorescent substance excitable under visible light, having higher photostability and a long fluorescence lifetime. Another subject is to provide a fluorescent substance consists of a non-natural amino acid applicable to peptide synthesis systems.Searching fluorescent substances, which are fluorescent amino acids and excitable under visible light, having the lowest possible molecular weight for a high photostability resulted in forming a condensed polycyclic aromatic compound by subjecting a compound having an acridone structure to substitution with an amino acid and further condensation with a benzene ring. Thus, the subject is achieved by the fluorescent substance consisting of amino acid-substituted benzoacridone derivative excitable under visible light.
    • 本发明的主题是提供在可见光下可激发的荧光物质,具有较高的光稳定性和较长的荧光寿命。 另一个主题是提供由适用于肽合成系统的非天然氨基酸组成的荧光物质。 在具有高光稳定性的情况下,以具有最低可能分子量的荧光氨基酸和可见光激发的荧光物质搜索导致通过使具有吖啶酮结构的化合物用氨基酸取代并进一步缩合形成稠合多环芳族化合物 与苯环。 因此,通过由可见光可激发的氨基酸取代的苯并吖啶酮衍生物构成的荧光物质来实现。
