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

open access: yesAdvanced 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

Isosteric Engineering of Enzymes: Overcoming Activity–Stability Trade‐Offs by Site‐Selective CH → N Substitutions

open access: yesAngewandte Chemie, EarlyView.
Coupling biosynthetic noncanonical amino acid production with genetic code expansion enables site‐specific incorporation of azatryptophans into PET‐degrading enzymes (PETases). By isosteric single‐atom editing of a conserved tryptophan, AzaPETases break the activity–stability trade‐off, delivering higher catalytic efficiency at elevated temperature and

Peptidthioester und Peptidtriazolderivate durch Duale Modifikation von Peptidthiosulfonaten auf dem Harz

open access: yesAngewandte Chemie, EarlyView.
Es wird eine Strategie zur dualen Modifikation von Peptiden auf der Festphase vorgestellt, die die S‐Alkinylierung von Peptidthiosulfonaten und eine regioselektive, iridiumkatalysierte Azid‐Thioalkin‐Zykloaddition umfasst. Dieses Verfahren ermöglicht zuverlässig den Zugang zu Peptiden mit komplexen, nicht‐kanonischen Modifikationen und ist mit ...
