Photocatalyzed Ring Expansion of α‐Ketosulfonylaziridines: Ready Access to δ‐Sultams

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
A novel radical–polar crossover (RPC) photoredox‐catalyzed reaction for the synthesis of δ‐sultams from N‐sulfonyl α‐ketoaziridines through a controlled ring opening–expansion process is presented. This method allows the easy access to sultams with an unprecedented substitution pattern in up to 85% yield and 2:1 d.r., and highlights the potential of ...

Making Blank Faces Expressive: Chemical Approaches to the Modification of Chemically Inert Peptides

Journal of Peptide Science, Volume 32, Issue 3, March 2026.
As an alternative to the conventional approach, which combines amino acid monomers in a one‐by‐one fashion to peptide derivatives, the chemical modification of existing peptides has attracted significant attention in recent years. However, such approaches generally target the reactive functional groups in cysteine and lysine residues, particularly in ...

Calprotectin Is a Circulating Biomarker and Potential Therapeutic Target for Sarcopenia in Chronic Obstructive Pulmonary Disease

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 1, February 2026.
ABSTRACT Background Sarcopenia, an important complication of chronic obstructive pulmonary disease (COPD), is significantly associated with increased mortality. Systemic inflammation is an important trigger of COPD‐related skeletal muscle dysfunction. Calprotectin is a damage‐associated molecular pattern involved in the inflammatory response, but its ...

Green synthesis of silver nanoparticles using fermentation extracts from a mangrove soil bacterium: morphological characterization, and antifungal activities against rice blast fungus

Pest Management Science, Volume 82, Issue 2, Page 2035-2047, February 2026.
This study synthesized silver nanoparticles (RFE‐AgNPs) with multifaceted inhibitory effects on Pyricularia oryzae using mangrove soil bacterial natural products and evaluated their toxicity effects on Artemia salina. Abstract BACKGROUND Rice blast, caused by Pyricularia oryzae, poses a formidable threat to global rice production.

Frame‐Shifted Synthesis of Oligoheterocycles as a Platform for Molecular Design

Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.
Modern chemistry seeks to turn the simple raw materials into complex molecules that matter in health, agriculture, and technology. Among these, oligoheterocycles stand out for their versatility, yet they are most often built by cross‐coupling reactions that often rely on expensive metal catalysts.

Symmetrical Imidazo[1,5‐a]pyridine Dimers as Novel Organic Light Emitters: Bidirectional Synthesis and Photoluminescence Characterization

European Journal of Organic Chemistry, Volume 29, Issue 3, January 22, 2026.
Imidazo[1,5‐a]pyridine dimers are synthesized via a bidirectional strategy and characterized by single‐crystal X‐ray diffraction. The key substitution position for tuning optical properties is identified. Photophysical studies, supported by density functional theory calculations, show fluorescence in the 490–580 nm range, with the most planar system ...
