Harnessing Synergistic Cooperation of Neighboring Active Motifs in Heterogeneous Catalysts for Enhanced Catalytic Performance

Advanced Materials, EarlyView.
This review examines the critical role of neighboring active motifs in heterogeneous catalysts, emphasizing how their synergistic cooperativity can be rationally designed to modulate catalytic properties. The discussion centers on the modulation of electronic and geometric structures, categorizing the catalytic systems into metal‐acid (Brønsted/Lewis ...

Direct Access to α,β‐Unsaturated γ‐Lactams via Palladium‐Catalysed Carbonylation of Propargylic Ureas.

Advanced Synthesis &Catalysis, Volume 367, Issue 5, March 4, 2025.
Abstract Additive carbonylations typically necessitate strong nucleophiles, such as alcohols or amines. In this study, we carbonylated a poorly nucleophilic urea, under oxidant‐free conditions. Our straightforward carbonylative strategy enables access to versatile α,β‐unsaturated γ‐lactams featuring an aminocarbonyl fragment, utilizing readily ...

Dimethyl Itaconate Alleviates Escherichia coli‐Induced Endometritis Through the Guanosine‐CXCL14 Axis via Increasing the Abundance of norank_f_Muribaculaceae

Advanced Science, EarlyView.
The research findings indicate that dimethyl itaconate (DI) alleviates Escherichia coli (E. coli) induced endometritis by modulating the gut microbiota and enriching the abundance of norank_f_Muribaculaceae, thereby increasing the production of guanosine.

Reactive Cysteines in Proteins are the Dominant Reductants for Platinum(IV) Prodrug Activation in Live Cells

Angewandte Chemie, EarlyView.
Pt‐Luc was developed as a pioneering bioluminescent reporter for real‐time monitoring of Pt(IV) reduction in live cells. Using this advanced reporter, we identified that reactive cysteines in proteins, rather than those in small molecules, predominantly mediate the reduction of Pt(IV) prodrugs.

Surface Engineering‐Induced d‐Band Center Down‐Regulation in High‐Entropy Alloy Nanowires for Enhanced Nanozyme Catalysis

Advanced Science, EarlyView.
PtRuFeCoNi HEA NWs are synthesized by adjusting the metal composition and surface‐engineered with PDA to create HEA NWs@PDA nanozymes with superior catalytic activities and photothermal properties. DFT calculations confirm that self‐polymerized PDA surface engineering moderately lowers the d‐band center of the HEAs, optimizes the surface charge ...
