Harnessing Carbenoid Reactivity From Imidazoles and Oxiranes

Advanced Synthesis &Catalysis, EarlyView.
The combination of azole compounds and oxiranes exhibits carbenoid reactivity at elevated temperatures, as demonstrated by the successful benzoin condensation of aromatic aldehydes. Using this catalytic system to polymerize bifunctional aldehyde/oxirane monomers yields thermosets with glass transition temperatures above 100°C.

ROS Activated NETosis of Bone Marrow CD55+ Intermediate Mature Neutrophils Through HIF1α‐PADI4 Pathway to Initiate Bone Aging

Advanced Science, EarlyView.
In this study, we find CD55+ neutrophils show activated NETosis within bone marrow, induce BMSC senescence and osteogenesis inhibition, finally leading to bone aging initiation. Mechanistically, ROS synergizes with the CD55‐driven HIF1α‐PADI4 pathway to promote NETosis.

Biocatalytic Nanoregulators Restore Joint Redox‐Immune Homeostasis in Rheumatoid Arthritis

Advanced Science, EarlyView.
Mesenchymal stem cell‐derived extracellular vesicles (EVs) coat ruthenium‐loaded metal‐organic frameworks (Ru@ZrMOF), creating a targeted therapeutic (Ru@ZrMOF/EVs). This platform scavenges ROS, generates oxygen, and polarizes macrophages from M1 to M2, alleviating inflammation, inhibiting pannus, promoting cartilage repair, and downregulating HIF‐1α ...

Vm–MSI: a Vancomycin–Antimicrobial Peptide Conjugate Combating Resistant Bacteria and Broadening the Antimicrobial Spectrum

Advanced Science, EarlyView.
A series of vancomycin‐antimicrobial peptide conjugates is synthesized and evaluated to identify the optimal combination. Vm‐MSI, selected from multiple candidates, exhibited potent activity against vancomycin‐resistant and Gram‐negative bacteria by disrupting membranes and inducing oxidative stress, thereby expanding vancomycin's antibacterial ...
