HeLa cells produce coelenterazine chemiluminescence in vitro.

, 2016
(A) 5x105 HeLa cells were imaged sequentially, at 5 min intervals for 1 hour. (B) Quantification of HeLa (black) or buffer (white) coelenterazine chemiluminescence at each time point (n = 3).

5‐HT2A receptor agonism by tert‐leucinamide and valinamide synthetic cannabinoids: In vitro and in vivo evidence

British Journal of Pharmacology, Volume 183, Issue 16, Page 4715-4734, August 2026.
Abstract Background and Purpose New synthetic cannabinoid receptor agonists (SCRAs) are associated with severe adverse effects, including unexpected psychiatric symptoms. These compounds are mainly active through their potent agonism on the cannabinoid receptors CB1 and CB2.

A coelenterazine-dependent luciferase from the deep-sea coral Anthoptilum murrayi Kölliker, 1880 (Cnidaria: Octocorallia: Pennatulacea)

bioRxiv
Bioluminescence is the production of visible light by living organisms through biochemical reactions in which specialized enzymes known as luciferases catalyze the oxidation of light-emitting substrates (luciferins), producing photons.

Presence of coelenterazine in mesopelagic fishes from the Strait of Messina

, 1995
Coelenterazine, a luciferine, and luciferase activity specific to coelenterazine were detected and assayed in various tissues of mid-water fishes, Argyropelecus hemigymnus, Chauliodus sloani, Myctophum punctatum, Vinciguerria attenuata and Cyclothone ...

Sulfuryl group transfer from coelenterazine sulfate to PAP by other sulfotransferases.

, 2022
We surveyed four sulfotransferases (STs) for their ability to transfer the sulfate from coelenterazine sulfate to PAP producing coelenterazine. The mouse estrogen ST was chosen based on sequence similarity (Fig 9) to the Coel-ST and the others based on ...

Es werde Licht! Licht als Antrieb und Regulator in synthetischen Zellen

Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.
Zellen sind Systeme außerhalb des Gleichgewichts, die ihre Eigenschaften in Raum und Zeit regulieren. In biomimetischen synthetischen Zellen bietet Licht eine einzigartige Möglichkeit, Vorgänge räumlich und zeitlich anzutreiben und zu kontrollieren.

NanoLuc/h-coelenterazine: an efficient pair for bioluminescence imaging in vivo and in vivo

Russian journal of hematology and transfusiology
Introduction. Bioluminescent labeling of tumor cells is becoming the standard in preclinical studies of novel anti-cancer drugs. Despite the variety of luciferases, many are not suitable for in vivo imaging.Aim: to compare different Nanolux substrates in

Maintain the light, long-term seasonal monitoring of luminous capabilities in the brittle star Amphiura filiformis

Scientific Reports
The European brittle star Amphiura filiformis emits blue light, via a Renilla-like luciferase, which depends on the dietary acquisition of coelenterazine.

Let There be Light! Light as an Engine and Regulator in Synthetic Cells

Angewandte Chemie International Edition, Volume 65, Issue 24, 8 June 2026.
Cells are out‐of‐equilibrium systems that regulate their spatiotemporal features. In biomimetic synthetic cells, light offers a unique way for energizing and regulating events in space and time. This review explores the implementation of light‐responsive tools in synthetic cells to replicate biological functions and enable new bioinspired behaviors ...
