Direct Access to α,β‐Unsaturated γ‐Lactams via Palladium‐Catalysed Carbonylation of Propargylic Ureas.

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 5, March 4, 2025.
Abstract Additive carbonylations typically necessitate strong nucleophiles, such as alcohols or amines. In this study, we carbonylated a poorly nucleophilic urea, under oxidant‐free conditions. Our straightforward carbonylative strategy enables access to versatile α,β‐unsaturated γ‐lactams featuring an aminocarbonyl fragment, utilizing readily ...

Self‐Adjusting Engineered Probiotic for Targeted Tumor Colonization and Local Therapeutics Delivery

open access: yesAdvanced Science, EarlyView.
Zou et al. developed an engineered strain of Escherichia coli Nissle 1917 with precise targeting abilities for colonization and on‐demand payload release. The engineered probiotic survives and embolizes tumors only in the presence of more than 5 mM L‐lactate. Furthermore, the introduction of an α‐hemolysin circuit enhances its anti‐tumor effect.

Tumor Microenvironment Triggered In Situ Coagulation of Supramolecularly Engineered Platelets for Precise Tumor Embolization

open access: yesAdvanced Science, EarlyView.
Occlusion of tumor blood vessels represents a promising yet challenging approach in cancer treatment. Herein, supramolecularly engineered platelets conjugated with morphology‐transformable nanoparticles is developed for precise tumor embolization. The engineered platelets actively accumulate at tumor sites following induced blood vessel injury.
