Aldehyde Electrophilicity and Ring Strain Govern Xylose Acetalization Pathways for Biobased Chemical Production

ChemSusChem, Volume 19, Issue 1, January 2026.
Reaction kinetics and operando heteronuclear single quantum coherence nuclear magnetic resonance studies revealed the reaction pathway of xylose acetalization with different aldehydes. Product distribution and yields were significantly influenced by aldehyde electrophilicity and the orientation of xylose hydroxyl groups.

The Silk Route to Green Catalysis: Silk Fibroin as a Recyclable Ligand for Iron‐Catalyzed Olefin Epoxidation

ChemSusChem, Volume 19, Issue 1, January 2026.
Iron coordinated on silk fibroin from Bombyx mori is easily prepared and catalyzes olefin epoxidation under mild, sustainable conditions with O2. With minimal iron loading, the catalyst is highly recyclable and fully regenerable, offering a green route to heterogeneous catalysis.

Natural Products Targeting Notch Signaling in Cancer: Mechanistic Insights and Food‐Based Chemoprevention Potential

Food Frontiers, Volume 7, Issue 1, January 2026.
The Notch signaling pathway plays a dual role in cancer, acting as both a tumor promoter and suppressor depending on cellular context. This review highlights how natural products modulate Notch signaling to inhibit tumor initiation, progression, angiogenesis, and cancer stem cell maintenance.

Analysis of Methylated Quaternary Ammonium Compounds Using Hydrophilic Interaction Liquid Chromatography Combined With Mass Spectrometry

Mass Spectrometry Reviews, Volume 45, Issue 1, Page 107-119, January/February 2026.
ABSTRACT Liquid chromatography‐mass spectrometry (LC–MS) is a powerful technique for the detection and quantification of methylated quaternary ammonium compounds (mQACs), such as acylcarnitines and methylated amino‐acid‐derived (betainized) compounds, in biological matrices.
