Synthesis of Cyanate Esters Based on Mono-O-Methylated Bisphenols with Sulfur-Containing Bridges

Molecules, 2019
We described a synthetic approach to bisphenol-based monocyanate esters based on mono-O-methylation of parental bisphenols followed by cyanation of the residual phenolic hydroxyl. Structures of the synthesized compounds were determined by the application

Support‐Controlled Reaction Pathways via Dynamic Sulfur‐Mediated Interfaces for Selective Urea Electrolysis

Advanced Functional Materials, EarlyView.
Sulfur‐doped graphitized carbon nanofibers act as adaptive catalyst–support platforms, enabling dynamic sulfur‐mediated reconstruction and strong metal–support interactions. This unique behavior enhances catalyst stability and controls reaction pathways, achieving highly selective urea oxidation (∼92% N2) coupled with efficient hydrogen evolution ...

Anti‐Carbamylated Protein Antibodies Stabilize Carbamylated Histone H3 to Promote Synovial Activation and Neutrophil Extracellular Trap‐Mediated Bone Loss in Rheumatoid Arthritis

Arthritis &Rheumatology, EarlyView.
Objective Carbamylation, a nonenzymatic post‐translational modification, contributes to rheumatoid arthritis (RA) pathogenesis. Anti‐carbamylated protein antibodies (anti‐CarP) occur in around 50% of patients with RA and associate with greater joint damage. Neutrophil extracellular traps (NETs) are a major source of carbamylated autoantigens. We sought

Anti–Carbamylated Fibrinogen Autoantibodies of IgG and IgA Isotypes Contribute to a Better Prognostic Stratification in Very Early Rheumatoid Arthritis: Data From the French National ESPOIR Cohort

Arthritis &Rheumatology, EarlyView.
Objective The aim of this study was to investigate the prevalence and longitudinal evolution of anti–carbamylated fibrinogen antibodies (ACa‐Fib) of IgG and IgA isotypes in early rheumatoid arthritis (RA) and determine whether these antibodies provide additional diagnostic and prognostic information beyond anti–cyclic citrullinated peptide (anti‐CCP ...

Carbon Dot Nano‐Spacers in Triazine Networks for Integrated Photothermal Seawater Desalination and H2O2 Production

Carbon Energy, EarlyView.
Cyanated carbon dots (CN‐CDs) are synthesized by the hydrothermal method with carboxymethyl cellulose and cyanobenzoic acid, and CD‐CTN is obtained in situ via cyclotrimerization of CN‐CDs. CD‐CTN possesses excellent photothermal catalytic H2O2 production in seawater, and desalted H2O2 could be obtained, which demonstrates the practical application for

An Electrophilic Uridine Building Block for Post‐Synthetic RNA Modification as Exemplified for Spin Labeling

Chemistry – A European Journal, EarlyView.
An electrophilic 5‐isothiocyanatomethyl uridine building block enables modular post‐synthetic RNA labeling with primary amine‐containing probes. Positioning the functionality in the major groove minimizes structural perturbation and allows facile conjugation of sensitive tags such as TEMPO spin labels for paramagnetic relaxation enhancement studies ...

Linear and Two‐Dimensional Infrared Spectroscopy of the Multifunctional Vibrational Probe, 3‐(4‐Azidophenyl) Propiolonitrile. Deperturbing a Fermi Triad by Isotopic Substitution

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Linear infrared spectroscopy combined with isotope labeling and density functional theory unravels the origin of a Fermi triad in a multifunctional vibrational chromophore. Ultrafast 2DIR‐spectroscopy reports directly on the dynamics and the intramolecular vibrational energy flow pathways in the isotopically deperturbed system. Abstract Infrared probes
