Abstract

The dimethylamino group of AkaLumine ((4. S)-2-[(1. E,3. E)-4-[4-(dimethylamino)phenyl]-1,3-butadien-1-yl]-4,5-dihydro-4-thiazolecarboxylic acid), a red-light-emitting firefly luciferin analogue, was replaced by cyclic amino groups (1-pyrrolidinyl, 1-piperidino, 1-azepanyl, and 4-morpholino) to give AkaLumine analogues exhibiting desirable bioluminescence with emission maxima in the red region (656-667 nm). In particular, a bioluminescence reaction of 1-pyrrolidinyl analogue with a recombinant Photinus pyralis luciferase showed a higher quantum yield than that with AkaLumine, giving an improved bioluminescence intensity. The 1-pyrrolidinyl analogue also showed the strongest luminescence in whole-body luciferase-expressing mice among the analogues, indicating that a quantum yield improvement of a luciferin analogue is effective to increase bioluminescence imaging intensity.
