Coelenterazine Analogs for Bioassays and Molecular Imaging
Coelenterazine (CTZ) is a common substrate of marine luciferases upon emission of bioluminescence (BL) in living organisms. Because CTZ works as a “luminophore” in the process of BL emission, the chemical modification has been centered for improving the optical properties of BL. In this review, we s...

| description | Coelenterazine (CTZ) is a common substrate of marine luciferases upon emission of bioluminescence (BL) in living organisms. Because CTZ works as a “luminophore” in the process of BL emission, the chemical modification has been centered for improving the optical properties of BL. In this review, we showcase recent advances in CTZ designs with unique functionalities. We first elucidate the light-emitting mechanisms of CTZ, and then focus on how the rational modification of CTZ analogs developed in recent years are connected to the development of unique functionalities even without luciferases, which include color tunability covering the visible region, specificity to various proteins (e.g., luciferase, albumin, and virus protein), and activatability to ions or reactive oxygen species (ROS) and anticancer drugs. This review provides new insights into the broad utilities of CTZ analogs with designed functionalities in bioassays and molecular imaging. |
