Luciferase‐free Luciferin Electrochemiluminescence

open access: yesAngewandte Chemie International Edition, 2022
AbstractLuciferin is one of Nature's most widespread luminophores, and enzymes that catalyze luciferin luminescence are the basis of successful commercial “glow” assays for gene expression and metabolic ATP formation. Herein we report an electrochemical method to promote firefly's luciferin luminescence in the absence of its natural biocatalyst ...

Bioluminescent Sensors for Ca++ Flux Imaging and the Introduction of a New Intensity-Based Ca++ Sensor

open access: yesFrontiers in Bioengineering and Biotechnology, 2021
Sensitive detection of biological events is a goal for the design and characterization of sensors that can be used in vitro and in vivo. One important second messenger is Ca++ which has been a focus of using genetically encoded Ca++ indicators (GECIs ...

Label-free phenotypic profiling identified D-luciferin as a GPR35 agonist. [PDF]

open access: yesPLoS ONE, 2012
Fluorescent and luminescent probes are essential to both in vitro molecular assays and in vivo imaging techniques, and have been extensively used to measure biological function.

Analysis of the Anticipatory Behavior Formation Mechanism Induced by Methamphetamine Using a Single Hair

open access: yesCells, 2023
While the suprachiasmatic nucleus (SCN) coordinates many daily rhythms, some circadian patterns of expression are controlled by SCN-independent systems. These include responses to daily methamphetamine (MAP) injections.

Structure-Functional Analysis of Human Cytochrome P450 2C8 Using Directed Evolution

open access: yesPharmaceutics, 2021
The human genome includes four cytochrome P450 2C subfamily enzymes, and CYP2C8 has generated research interest because it is subject to drug–drug interactions and various polymorphic outcomes.

Luciferins Under Construction: A Review of Known Biosynthetic Pathways

open access: yesFrontiers in Ecology and Evolution, 2021
Bioluminescence, or the ability of a living organism to generate visible light, occurs as a result of biochemical reaction where enzyme, known as a luciferase, catalyzes the oxidation of a small-molecule substrate, known as luciferin.

A luciferin analogue generating near-infrared bioluminescence achieves highly sensitive deep-tissue imaging

open access: yesNature Communications, 2016
D-luciferin is the standard bioluminescent substrate for in vitro and in vivo imaging. Here the authors introduce AkaLumine-HCl, a soluble luciferin analogue with a near-infrared emission maximum, which allows deep tissue imaging at lower concentrations ...

Electrochemically Generated Luminescence of Luminol and Luciferin in Ionic Liquids

open access: yesChemElectroChem, 2023
Electrochemiluminescence (ECL) is the generation of light triggered by an electrochemical reaction. ECL has been extensively studied in solvent‐based electrolytes, but there is a lack of data on using electrode reactions to populate an excited‐state ...

Synthesis of N-peptide-6-amino-D-luciferin Conjugates

open access: yesFrontiers in Chemistry, 2018
A general strategy for the synthesis of N-peptide-6-amino-D-luciferin conjugates has been developed. The applicability of the strategy was demonstrated with the preparation of a known substrate, N-Z-Asp-Glu-Val-Asp-6-amino-D-luciferin (N-Z-DEVD-aLuc).
