Metabolic fate of drugs of abuse and new psychoactive substances: A pilot study on a novel workflow using a zebrafish embryo model combined with human microdosing

British Journal of Clinical Pharmacology, EarlyView.
Aim The aim of this study was to develop a novel workflow to identify human urine biomarkers for drugs of abuse and new psychoactive substances. Metabolites of amphetamine, cocaine, LSD, MDMA, methamphetamine, THC, MDMB‐CHMICA, and MDPPP were first identified in a zebrafish embryo (ZE) metabolism study followed by comparison to most abundant human ...

Photothermal CO2 Hydrogenation: Reactions, Mechanisms, and Catalyst Design

Carbon Energy, EarlyView.
Reactions, mechanisms, and catalyst design for photothermal CO2 hydrogenation. ABSTRACT Photothermal CO2 hydrogenation has attracted extensive attention because it provides a green and sustainable approach to fuel and chemicals production. The photothermal catalyst plays a critical role in CO2 conversion through a range of reactions.

Formation of a Nickel−Methyl Species in Methyl-Coenzyme M Reductase, an Enzyme Catalyzing Methane Formation

Journal of the American Chemical Society, 2007
An organometallic methyl−nickel species was detected in the enzyme methyl-coenzyme M reductase (MCR). This is the key enzyme in microbial methane production and is probably also involved in anaerobic methane oxidation. Incubation of MCR with 13C-bromomethane results in the formation of an electron paramagnetic resonance (EPR) active nickel−methyl ...

Formic Acid Stabilization on Supported Ionic Liquid Phases: Insights from Solid‐State NMR Spectroscopy

Chemistry – A European Journal, EarlyView.
Solid‐state NMR spectroscopy reveals insights into interactions between formic acid and molecularly‐modified silica surfaces. Our findings contribute to a mechanistic understanding of the stabilization of formic acid by ionic liquid structures, with significant implications for the formic acid production from CO2 hydrogenation and adaptive catalysis ...

Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

Chemistry – A European Journal, EarlyView.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

Catabolism and interactions of uncultured organisms shaped by eco-thermodynamics in methanogenic bioprocesses

Microbiome, 2020
Background Current understanding of the carbon cycle in methanogenic environments involves trophic interactions such as interspecies H2 transfer between organotrophs and methanogens. However, many metabolic processes are thermodynamically sensitive to H2
