Synthesis, Chemi- and Bioluminescence Properties, and Photolysis of a Coelenterazine Analogue Having a Photoreactive Azido Group

Abstract

Abstract A photoreactive analogue of coelenterazine having an azido group was synthesized. The analogue showed similar chemi- and bioluminescence properties to those of the natural coelenterazine. Photolysis of the analogue in the presence of diethylamine gave a derivative azepine as the major product.
