Degrading GPX4 via Biomimetic Nanoparticle‐Mediated In Situ Synthesis of Deep‐Learning‐Designed Binder‐Degron Chimeras for Prostate Cancer Therapy

open access: yesAdvanced Science, EarlyView.
A deep‐learning‐designed binder is fused to a combinatorial degron to create a binder‐degron chimera (bdC) that recruits the CUL2‐RING ubiquitin ligase complex. Encapsulation in a prostate‐cancer‐targeted, CD47‐camouflaged nanocarrier enables tumor‐specific in situ bdC expression, triggering GPX4 degradation and ferroptosis, thereby establishing a ...

In Situ Bioorthogonal Synthesis of PROTACs via Dual‐Responsive Cleavage for Synergistic Photo‐Immunotherapy

open access: yesAdvanced Science, EarlyView.
A bioactive self‐delivering SNAP‐TAC platform responds to tumor‐associated cathepsin B and glutathione, enabling in situ bioorthogonal synthesis of a BRD4‐degrading proteolysis‐targeting chimera within the tumor microenvironment. The resulting BRD4 degradation and PD‐L1 downregulation synergize with photodynamic therapy‐induced immunogenic cell death ...

Hydrogel Phase Transition‐Driven Soft Gating Circumvents Debye Screening for Advanced Biosensing

open access: yesAdvanced Science, EarlyView.
A 3D soft gate utilizes a macroscopic hydrogel phase transition to effectively circumvent Debye screening in high‐salt environments. The intact matrix maximizes transmembrane ion flux via volumetric Donnan enrichment and superhydrophilicity. Target‐triggered network disassembly abolishes these effects, introducing a synergistic physical barrier.

H4K12 Lactylation Regulates NDUFS7 to Drive Microglia Reverse Electron Transport in Spinal Cord Injury

open access: yesAdvanced Science, EarlyView.
Lactate accumulation after SCI promotes H4K12la lactylation, which upregulates NDUFS7, triggering mitochondrial RET and ROS, enforcing pro‐inflammatory microglial polarization. MM@mPTC, a biomimetic nanotherapeutic, degrades LDHA in activated microglia, reducing H4K12la lactylation and blocking RET, thus curbing ROS, fostering a reparative phenotype ...

Checkpoint‐Directed Glycoengineering Reprograms the Vascular Lumen for Siglec‐Mediated Immune Regulation

open access: yesAdvanced Science, EarlyView.
Checkpoint‐directed glycoengineering installs sialylated ligands on the donor vascular lumen during ex vivo preservation, creating a localized Siglec‐7/9‐engaging interface. The engineered glycocalyx suppresses immune‐cell activation, complement deposition, and microvascular injury in arterial and kidney allografts while preserving endothelial ...

Molecular Electrocatalysis Coupled With a Palladium Membrane Reactor Affords Selective Nitrogen Reduction

open access: yesAdvanced Science, EarlyView.
A palladium membrane reactor delivers active hydrogen to homogeneous nickel terpyridine catalysts, which then selectively hydrogenate dinitrogen to ammonia. ABSTRACT Ammonia production is a cornerstone of modern industry and society, yet the conventional Haber–Bosch process accounts for nearly 2% of the global CO2 emissions. A promising and potentially

The Azidofunctionalization of Alkenes

open access: yesChemistryEurope
The azidofunctionalization of alkenes has emerged as a powerful difunctionalization strategy, expanding the toolbox of synthetic chemistry. This transformation enables the simultaneous installation of an azide and a second functional group onto an alkene,
