BMEMat, EarlyView.The synthesized CCzymes possess both antioxidant enzyme activity and pharmacological properties inherent to Coptis chinensis. By their antioxidant enzyme activity, CCzymes can attenuate oxidative stress within the inflammatory region of ulcerative colitis (UC), while their pharmacological activity acts on macrophage polarization and the intestinal ...

Synthesis, characterization, and crystal structure of 2-(2-azidophenyl)-3-oxo-3H-indole 1-oxide
Acta Crystallographica Section E: Crystallographic CommunicationsAn attempt to explore the reactivity of the nitro group in the presence of gold catalysis in comparison to the azide group yielded intriguing results. Surprisingly, only the nitro group exhibited reactivity, ultimately giving rise to the formation of the

Advancing design strategies in smart stimulus‐responsive liposomes for drug release and nanomedicine
BMEMat, EarlyView.Schematic illustration of stimulus‐responsive liposomes designed for controlled drug release and nanomedicine. The innermost circle represents different liposomal structures, including unilamellar, multilamellar, and multivesicular liposomes. The middle layer illustrates the responsive phospholipid components.

ChemistryEurope, EarlyView.Cathepsin B‐sensitive peptide–adjuvant conjugates are designed, synthesized, and evaluated to deliver an antigenic peptid and an adjuvant targeting Toll‐like receptors 7 and 8 (TLR7/8) to antigen presenting cells. The adjuvant is released by cathepsin B resulting in antigen presentation and TLR mediated T cell activation.

Skeletal Editing from Pyridine to Aniline via C‐Insertion and N‐Isomerization
ChemistryEurope, EarlyView.A concise protocol is presented that converts pyridines into anilines by externalizing the original pyridine nitrogen at either the "ipso" or "ortho" position, which results in para or meta‐primary aniline products. A key carbene‐insertion step precedes nitrogen migration, preserving both ring size and overall structure.

ChemistryEurope, EarlyView.In this work, a catalytic enantioselective imidation approach is presented for the preparation of enantioenriched sulfinamidines from sulfenamides, employing a chiral dirhodium(II) tetracarboxylate catalyst. This method enables the imidation of N,N‐bisalkyl sulfenamides in yields of up to 98% and enantiomeric ratios up to 98:2, with a catalyst loading ...
