Precision Chemistry for Protein Lysine Modification

Chemistry – A European Journal, EarlyView.
Selective modification of lysine residues is challenging due to their similar intrinsic reactivity. Inspired by enzymatic recognition, ligand‐guided electrophiles enable site‐selective labeling and functionalization, while ligand‐guided catalyses achieve regioselective installation of bio‐relevant post‐translational modifications.

Cross‐Dehydrogenative Coupling Reactions With Redox‐Active Guanidine Reagents

Chemistry – A European Journal, EarlyView.
ABSTRACT Cross‐dehydrogenative coupling (CDC) reactions are attractive and environmentally friendly ways to form new C‐C and other element‐element bonds. Here, we report the first CDC reactions triggered by a redox‐active guanidine reagent. N‐phenyltetrahydroisoquinoline and derivatives with electron‐donating and withdrawing substituents at the N ...

Synthesis of the Core Tetracycle of the Spirobiflavonoid Daphnodorin C

European Journal of Organic Chemistry, EarlyView.
Core spirotetracycle of daphnodorin C: Oxidative ring contraction of benzofuro[3,2‐b]chromenones affords novel 2,3′‐spirobi[benzofuran]diones, rather than the isomeric spiroketals. The first synthesis of the spirobi[benzofuran]dione core structure of the spirobiflavonoid daphnodorin C is described.

Formation of Bicyclic Skeletons by Aerobic, Manganese‐Mediated Cyclization of β‐Oxoesters

European Journal of Organic Chemistry, EarlyView.
Manganese(III) promotes aerobic radical cyclization reactions of β‐oxoesters with an ω‐alkenyl side chain at the β’‐position to give bicyclic products with a 1,4‐dicarbonyl structure. Bicyclic perhydro‐pentalene, ‐indene, and ‐azulene, as well as decaline skeletons were accessed by aerobic manganese(III)‐mediated radical cyclizations of cyclic β ...

Retro‐Hetero‐Michael Addition Strategies in Organic Synthesis

European Journal of Organic Chemistry, EarlyView.
In this review, synthetic approaches to carbo‐ and heterocyclic compounds, including natural products, published in the last 15 years (2011–2025) which have either relied upon or included a retro‐hetero‐Michael addition step at any stage are discussed.

Diphenyl Disulfide‐Promoted Racemization of 1‐Arylethanols for Photobiocatalytic Dynamic Kinetic Resolution

European Journal of Organic Chemistry, EarlyView.
Purple‐light activation of aggregated diphenyl disulfide unlocks the photocatalyst‐free racemization of 1‐arylethanols. The resulting sulfur radical process operates under mild conditions and couples with the enzymatic acylation by Candida antarctica lipase B in a photobiocatalytic dynamic kinetic resolution, revealing new opportunities for sulfur ...

“Effects of High‐Intensity Ultrasound on the Structural, Technofunctional, and Allergenic Properties of Groundnut (Arachis hypogaea L.) Protein Isolates: A Review”

Food Chemistry International, EarlyView.
ABSTRACT The growing global demand for sustainable, nutritionally balanced protein sources has intensified interest in plant‐derived proteins, particularly those derived from oilseeds such as groundnut (Arachis hypogaea L.). However, although groundnut protein isolates (GPIs) have high nutritional quality, they exhibit limitations in technofunctional ...

Advances in protein–polyphenol complexation: Unraveling mechanisms, modulation, and functional outcomes

Food Biomacromolecules, EarlyView.
Abstract Polyphenolic compounds have attracted increasing market demand and extensive attention due to their potential health benefits and bioactivities. Meanwhile, proteins are widely used in the food industry for their nutritional and functional properties. However, the application of proteins in the food industry is often limited by challenges, such

Polydatin Alleviates APAP‐Induced Hepatotoxicity by Targeting C/EBPβ to Suppress the NLRP3 Inflammasome Signaling Pathway

iNew Medicine, EarlyView.
PD alleviates APAP‐induced ALI by inhibiting the NLRP3 inflammasome signaling pathway. C/EBPβ is identified as a direct target via multimethod validation. PD promotes the deacetylation of C/EBPβ via Sirt1. The Sirt1/C/EBPβ/NLRP3 signaling axis is defined for PD's hepatoprotective effect.
