Photocatalyzed Ring Expansion of α‐Ketosulfonylaziridines: Ready Access to δ‐Sultams
Angewandte Chemie, EarlyView.A novel radical–polar crossover (RPC) photoredox‐catalyzed reaction for the synthesis of δ‐sultams from N‐sulfonyl α‐ketoaziridines through a controlled ring opening–expansion process is presented. This method allows the easy access to sultams with an unprecedented substitution pattern in up to 85% yield and 2:1 d.r., and highlights the potential of ...

Advanced NanoBiomed Research, EarlyView.Encapsulated acriflavine (ACF) and copper oxide nanoparticles (CuO NPs) are coreleased from coaxial nanofibers, producing synergistic antiglioblastoma multiforme effects. ACF suppresses the hypoxia‐inducible factor 1α pathway related to many downstream factors for tumor growth, while CuO NPs generate reactive oxygen species that assist cuproptosis ...

Dual Modality Semiconducting Polymer Nanoparticles for Use in Optical and Magnetic Resonance Imaging
Advanced NanoBiomed Research, EarlyView.Well‐defined dual‐modality semiconducting polymer nanoparticles composed of red‐emitting conjugated polymers functionalized with novel gadolinium‐based contrast agents have been prepared. The assemblies show a greatly enhanced relaxivity performance compared to the clinical standard, Dotarem, while offering ultrabright fluorescence, ideal for optical ...

Site‐Selective Peptide and Protein Functionalization with Cyclopropenium Cations
Angewandte Chemie, EarlyView.A cysteine‐selective bioconjugation using aromatic cyclopropenium cations is reported. The reaction proceeds rapidly under aqueous conditions, enabling site‐selective installation of tetrasubstituted cyclopropene rings on peptides and proteins. The method shows preference for internal cysteines and provides conjugates that serve as efficient radical ...
