A Postbiotic‐Inducing Ganoderma applanatum Polysaccharide Repairs the Intestinal Barrier via a Phocaeicola vulgatus ‐ Tridecylic Acid Axis

Advanced Science, EarlyView.
This study identifies GAP2, a bioactive polysaccharide fraction derived from Ganoderma applanatum, as a postbiotic inducer that repairs intestinal barrier damage in a gut microbiota‐dependent manner. GAP2 enriches Phocaeicola vulgatus, which degrades GAP2 and promotes tridecylic acid production, triggering Rho/CDC42 signaling and tight‐junction ...

Macrocyclization of ω‐Isocyano Aldehydes

Angewandte Chemie, EarlyView.
The ω‐isocyano aldehydes readily undergo cyclization to afford α‐acyloxy, α‐hydroxy, α‐acetamido, and α‐keto macrolactams, as well as tetrazole‐fused macrocycles, via C(sp3)─C(sp2) bond formation, providing access to diverse α‐functionalized medium‐sized lactams and macrolactams. ABSTRACT Medium‐sized rings and macrocycles constitute a privileged class

A ROS‐Responsive and Mucoadhesive Thermosensitive Hydrogel Encapsulated with Mizoribine for Synergistic Dry Eye Therapy

Advanced Science, EarlyView.
The ROS‐responsive in situ thermosensitive MZR@SPPP hydrogel system enables dual‐stage drug loading and sustained ocular delivery. Upon administration, it gelates at ocular surface temperature, enhancing ocular adhesion. By scavenging free radicals, restoring NRF2‐mediated antioxidant defense and mitochondrial homeostasis, and suppressing inflammatory ...

Chalcogen‐Bond‐Driven Electrochemical Bromide Sequestration in Benzothiazole‐Functionalized Covalent Organic Frameworks

Angewandte Chemie, EarlyView.
To address the unresolved challenge of selective bromide removal from reverse‐osmosis permeate, we developed benzothiazole‐functionalized COF/rGO electrodes that exploit directional chalcogen bonding to preferentially capture Br− over Cl−. The mesoporous BTzTp@rGO electrode achieved a maximum Br− uptake of 36.7 mg g−1, a Br−/Cl− selectivity factor of ...
