Trimerization of aromatic nitriles [PDF]

open access: yes, 1977
Triazine compounds and cross-linked polymer compositions were made by heating aromatic nitriles to a temperature in the range of about 100 C to about 700 C, in the presence of a catalyst or mixture of catalysts.

Synthesis of Sulfur Enriched Cyclohexenes via the Tungsten‐Promoted Dearomatization of a Phenyl Sulfone

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 9, 2 March 2026.
A method for synthesizing sulfur‐substituted cyclohexenes is reportedthat leverages the η2‐coordination of a phenyl sulfone to [WTp(NO)(PMe3)] (Tp = trispyrazolylborate). Three sequential protonation and nucleophilic additions to the bound arene, followed by oxidative decomplexation, affords functionalized cyclohexenes bearing sp3‐ and sulfur‐enriched ...

Short-chain fatty acids affect skeletal muscle composition, fiber recruitment, and metabolism of the small yellow croaker (Larimichthys polyactis)

open access: yesAquaculture Reports
Recent studies have revealed that intestinal short-chain fatty acids (SCFAs) can affect muscles muscle metabolism in mammals by promoting glycogen metabolism and lipid oxidation.

A Synthetic Model of the Nonheme Iron–Superoxo Intermediate of Cysteine Dioxygenase [PDF]

open access: yes, 2018
A nonheme Fe(II) complex (1) that models substrate-bound cysteine dioxygenase (CDO) reacts with O2 at −80 °C to yield a purple intermediate (2). Analysis with spectroscopic and computational methods determined that 2 features a thiolate-ligated Fe(III ...

Under the ROS…thiol network is the principal suspect for autophagy commitment. [PDF]

open access: yes, 2010
Low molecular weight and protein sulphydryls undergo reactive oxygen species (ROS)-mediated oxidation. However, in contrast to the irreversible damages that oxidative conditions yield on biomolecules, the oxidation of reactive cysteines frequently ...

Medical Gas Plasma Inactivates Adenoviruses via Capsid Oxidation

open access: yesSmall, Volume 22, Issue 15, 12 March 2026.
Oxidative modification of three adenoviral capsid proteins after gas plasma treatment. Schematic representation of the viral infection process, starting with the initial attachment of the virus via its fiber protein binding to the cellular receptors (CAR and/or CD46). In the secondary attachment step, the penton base binds to integrin structures on the

An iron-oxygen intermediate formed during the catalytic cycle of cysteine dioxygenase [PDF]

open access: yes, 2016
Cysteine dioxygenase is a key enzyme in the breakdown of cysteine, but its mechanism remains controversial. A combination of spectroscopic and computational studies provides the first evidence of a short-lived intermediate in the catalytic cycle.

Crystal structure of plant γ‐glutamyl peptidase 1: implications for sulfur metabolism and secondary metabolite biosynthesis

open access: yesThe FEBS Journal, Volume 293, Issue 5, Page 1400-1414, March 2026.
The crystal structures of Arabidopsis thaliana γ‐glutamyl peptidase 1 (GGP1), including the covalent intermediate state, were determined. GGP1 is involved in both glutathione degradation in the primary metabolism and glutathione conjugate processing in the secondary metabolism of glucosinolate and camalexin biosynthesis.

On the Origin of Western Diet Pathologies [PDF]

open access: yes, 2010
The ratio of the two sulfur-containing amino acids, methionine (Met) and cysteine (Cys), may be a determining factor for which foods contribute to longevity and health. It is shown here that substantially more Met than Cys is consistently found in foods,

Biophysical Features of Bacillithiol, the Glutathione Surrogate of Bacillus subtilis and other Firmicutes [PDF]

open access: yes, 2013
Bacillithiol (BSH) is the major low-molecular-weight (LMW) thiol in many low-G+C Gram-positive bacteria (Firmicutes). Evidence now emerging suggests that BSH functions as an important LMW thiol in redox regulation and xenobiotic detoxification, analogous
