Interestingly, only the D-form of firefly luciferin produces light by luciferin-luciferase (L-L) reaction. Certain firefly luciferin analogs with modified structures maintain bioluminescence (BL) activity; however, all L-form luciferin analogs show no BL activity. To this date, our group has developed luciferin analogs with moderate BL activity that produce light of various wavelengths. For in vivo bioluminescence imaging, one of the important factors for detection sensitivity is tissue permeability of the number of photons emitted by L-L reaction, and the wavelengths of light in the near-IR (NIR) range (700-900 nm) are most appropriate for the purpose. Some NIR luciferin analogs by us had performance for in vivo experiments to make it possible to detect photons from deep target tissues in mice with high sensitivity, whereas only a few of them can produce NIR light by the L-L reactions with wild-type luciferase and/or mutant luciferase. Based on the structure-activity relationships, we designed and synthesized here a luciferin analog with the 5-allyl-6-dimethylamino-2-naphthylethenyl moiety. This analog exhibited NIR BL emissions with wild-type luciferase (max = 705 nm) and mutant luciferase AlaLuc (max = 655 nm).
