An object of the present invention to provide a firefly luciferin and firefly luciferin analog that are modified to maintain luminescent activity by luciferase in a firefly bioluminescent system. In particular, it is an object of the present invention to provide a new luminescent substrate for which the emission wavelength in a firefly bioluminescent system is shifted to a longer wavelength than that of a conventional luminescent substrate. The present invention provides a luciferin in which the benzothiazole ring moiety has been modified at the 7-position, a luciferin analog in which the benzene ring moiety has been modified at the 6-position, and a luciferin analog in which the 6-(dialkylamino)-2-naphthalenyl moiety has been modified at the 5-position.
本发明的目标是提供一种经过改性的萤火虫荧光素和萤火虫荧光素类似物,以维持萤火虫生物发光系统中荧光酶的发光活性。特别是,本发明的目标是提供一种新的荧光底物,其在萤火虫生物发光系统中的发射波长比传统荧光底物的发射波长更长。本发明提供了一种荧光素,其中苯并噻唑环部分在7位被改性,一种荧光素类似物,其中苯环部分在6位被改性,以及一种荧光素类似物,在6-(二烷基氨基)-2-萘基部分在5位被改性。
