Coelenterazine: a two-stage antioxidant in lipid micelles

Free Radical Biology and Medicine, 2004
Coelenterazine is a luciferin found in many marine bioluminescent organisms. This luciferin also possesses high antioxidant properties and an exceptional ability to protect cells exposed to oxidative stress. It has been suggested that coelenterazine's antioxidative mechanisms include the formation of an oxidation product, coelenteramine, also endowed ...

Ca2+-Triggered Coelenterazine-Binding Protein Renilla: Expected and Unexpected Features

International Journal of Molecular Sciences, 2023
Ca2+-triggered coelenterazine-binding protein (CBP) is a natural form of the luciferase substrate involved in the Renilla bioluminescence reaction. It is a stable complex of coelenterazine and apoprotein that, unlike coelenterazine, is soluble and stable

New red-shifted coelenterazine analogues with an extended electronic conjugation

Tetrahedron Letters, 2012
A new promising approach to the development of red-shifted coelenterazine analogues was described. In order to alter the photochemical properties of native coelenterazine, we have designed and synthesized analogues bearing a new electron-rich structure ...

Bioluminescent Properties of Semi-Synthetic Obelin and Aequorin Activated by Coelenterazine Analogues with Modifications of C-2, C-6, and C-8 Substituents

International Journal of Molecular Sciences, 2020
Ca2+-regulated photoproteins responsible for bioluminescence of a variety of marine organisms are single-chain globular proteins within the inner cavity of which the oxygenated coelenterazine, 2-hydroperoxycoelenterazine, is tightly bound. Alongside with

Coelenterazine-dependent luciferases

Biochemistry (Moscow), 2015
Bioluminescence is a widespread natural phenomenon. Luminous organisms are found among bacteria, fungi, protozoa, coelenterates, worms, molluscs, insects, and fish. Studies on bioluminescent systems of various organisms have revealed an interesting feature - the mechanisms underlying visible light emission are considerably different in representatives ...

Three Efficient Methods for Preparation of Coelenterazine Analogues

Chemistry - A European Journal, 2016
AbstractThe growing popularity of bioluminescent assays has highlighted the need for coelenterazine analogues possessing properties tuned for specific applications. However, the structural diversity of known coelenterazine analogues has been limited by current syntheses. Known routes for the preparation of coelenterazine analogues employ harsh reaction
