Firefly luciferase adenylates and oxidizes d-luciferin to chemically generate visible light and is widely used for biological assays and imaging. Here we show that both luciferase and luciferin can be reengineered to extend the scope of this light-emitting reaction. d-Luciferin can be replaced by synthetic luciferin analogues that increase near-infrared photon flux >10-fold over that of d-luciferin
This disclosure relates to luciferin amides of formula (I) shown below:
Each variable in formula (I) is defined in the specification. These compounds can be used to detect fatty acid amide hydrolase activities in vitro, in live cells, or in vivo.
