Human Leukocyte Elastase Triggered Nanoparticles for Targeted Antimicrobial Delivery and Oral Microbial Modulation

Advanced NanoBiomed Research, EarlyView.
This study explores enzyme‐responsive nanoparticles for targeted antimicrobial release in inflamed oral environments. Nanoparticles formed by complexing peptides and chlorhexidine respond to human leukocyte elastase and release chlorhexidine selectively. P7 (ECAAPVCE)‐based formulations show optimal properties and stability, with antimicrobial activity

Chemoenzymatic Synthesis of Well‐Defined α(2,8)‐ and α(2,9)‐Linked Oligosialosides

Angewandte Chemie, EarlyView.
Well‐defined α(2,8)‐ and α(2,9)‐linked oligosialic acids of different lengths can be prepared by employing recombinant bacterial polysialyltransferases in combination with chemically modified CMP‐Neu5Ac derivatives. After transfer, a sialoside is formed bearing an artificial entity, which blocks further glycosylation.

Flavin Catalysts in Organic Synthesis

Angewandte Chemie, EarlyView.
Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.

Inverse Vulcanization Through Epoxide Chemistry: A Low Temperature Non‐Olefin Route to Sulfur‐Rich Polymer Networks

Angewandte Chemie, EarlyView.
Epoxide monomers undergo base‐catalyzed ring‐opening copolymerization with elemental sulfur to afford sulfur‐rich polymers under mild conditions. The resulting materials exhibit excellent mechanical performance, strong adhesion (up to 10 MPa on stainless steel), and outstanding reprocessability.
