Fragmentation of Vancoresmycin Reveals a Strong Dependence on Global Molecular Architecture for Antibacterial Activity

ChemMedChem, Volume 21, Issue 15, 14 August 2026.
Fragmentation of the natural product vancoresmycin reveals an essential role of global architecture for biological potency. Vancoresmycin is a structurally complex tetramic‐acid‐containing natural product with potent activity against Gram‐positive bacteria, yet its structure–activity relationships remain poorly defined.

Polydopamine-mediated in situ synthesis of gold nanoparticles uniformly distributed on silk fibers as reusable catalysts for efficient 4-nitrophenol reduction

Journal of Industrial Textiles
Developing green fibrous materials with uniformly distributed metal nanoparticles for highly efficient and recyclable catalysis remains a major challenge. Herein, we developed a simple, effective, and green method to immobilize gold nanoparticles (AuNPs)

Auto‐Click Synthesis of a Copper(I)–N‐Heterocyclic Carbene Porous Organic Polymer and Its Transmetalation to Palladium(II) for Azide–Alkyne Cycloaddition and Cross‐Coupling Reactions

European Journal of Inorganic Chemistry, Volume 29, Issue 23, 13 August 2026.
An azide‐functionalized Cu(I)–NHC complex acts as both a monomer and a catalyst in an auto‐click polymerization, yielding a Cu(I)–NHC polymer that can be transmetalated to Pd(II). The two materials catalyze copper‐catalyzed azide–alkyne cycloaddition, C–N/C–O coupling, and Suzuki–Miyaura reactions, while copper reloading restores activity.

Targeting Golgi–STING Signaling to Reprogram Innate and Adaptive Immunity for the Treatment of Implant‐Associated Infections

Advanced Science, Volume 13, Issue 43, 3 August 2026.
This study presents an ultrasound‐responsive nanoplatform, CS‐BT@MZ@NEs, with a BaTiO3/Mn‐Zif‐8 core and a chondroitin sulfate coating for Golgi targeting. By leveraging neutrophil hitchhiking, it enables targeted delivery to infection sites. Under ultrasound stimulation, CS‐BT@MZ@NEs generates ROS and modulates Golgi pH to activate cGAS–STING ...

Boosting the Photocatalytic Performance of Layered Double Hydroxides by In Situ Reactions with Metal Nanoclusters

Aggregate, Volume 7, Issue 8, August 2026.
An interfacial engineering strategy based on in situ reactions between metal nanoclusters and layered double hydroxides enables simultaneous nanocluster size regulation, heterojunction construction, and mesopore generation. The reconstructed interface enhances visible‐light harvesting, charge separation, and mass transport, providing a general strategy

Physiologically‐based pharmacokinetic modelling of uridine 5′‐diphosphoglucorosultransferase (UGT) substrate drugs in pregnant women

British Journal of Clinical Pharmacology, Volume 92, Issue 8, Page 2764-2776, August 2026.
Aims While pregnancy‐related changes in phase I enzyme activity are well‐documented, less is known about the impact on phase II enzymes. This study aimed to test the hypothesis that changes in the pharmacokinetics (PK) of uridine 5′‐diphosphoglucuronosyltransferase (UGT) substrates during pregnancy result from altered enzyme expression or activity ...
