Metal‐Catalyzed Benzannulation: Recent Advances in Catalyst Design, Mechanistic Insights, and Aromatic Framework Construction

The Chemical Record, EarlyView.
This review offers a contemporary overview of metal‐catalyzed benzannulation (2018–present) encompassing transition, main‐group, post‐transition, and rare‐earth‐metal catalysts. It systematically highlights catalyst design, mechanistic insights, stereo‐ and regioselectivity, and synthetic applications toward aromatic and heteroaromatic scaffolds, while

Four‐dimensional immuno‐mechanobiomaterials: Dynamic material cues that program host response to prevent fibrosis and enable regeneration

VIEW, EarlyView.
Dynamic immuno‐mechanobiomaterials with time‐programmed mechanical adaptation orchestrate host responses through precise mechanotransduction and immune‐stromal regulation. These adaptive biomaterials minimize mechanical mismatch, attenuate the forign dy response and fibrosis, promote angiogenesis and controlled extracellular matrix remodeling, and ...

Brief encounters and lasting impressions—How target protein half‐life affects reactive metabolite signaling

The FEBS Journal, EarlyView.
Lipid‐derived reactive electrophile molecules (REMs) are generated from fatty acids through lipoxygenase or cyclooxygenase‐assisted catalysis, or free radical‐induced lipid peroxidation events. REMs so‐produced covalently modify nearby protein‐cysteines, and in the case of ‘first responder’ proteins, can trigger gain‐of‐function signaling with context ...

Liquid Chromatography Coupled With High‐Resolution Mass Spectrometry Profiling of Metabolites in Cassia alata Flower Extracts and Their DPPH Free Radical Scavenging Activity

Analytical Science Advances, Volume 7, Issue 2, December 2026.
ABSTRACT Cassia alata flowers remain phytochemically under‐characterized relative to the leaves. However, floral tissues can harbour distinct and, in some species, more abundant phenolic and flavonoid profiles, representing an unexploited source of antioxidant phytochemicals with potential functional‐food and nutraceutical relevance. Also, Cassia alata

Recyclable and Degradable Covalent Adaptable Polymer Networks (CANs) Based on Dynamic Thiol–Yne Reactions

Journal of Applied Polymer Science, Volume 143, Issue 44, November 20, 2026.
Covalent adaptable networks based on activated alkynes, that is, alkynones, and multifunctional thiols (three and tetrafunctional) are tested in two different recycling strategies: (i) mechanical recycling based on their vitrimeric properties and (ii) chemical recycling based on the reversible thiol addition on the vinylene compound.

Curvature‐Induced Kinetic Trapping in Chemical Reactions

Journal of Computational Chemistry, Volume 47, Issue 30, November 15, 2026.
Reaction path curvature helps to detect obstacles to reaction progress in the absence of activation energy barriers. ABSTRACT Crossing an activation energy barrier in a chemical reaction needs time because enough kinetic energy needs to redistribute into the barrier‐crossing mode.
