Functional and Network PHAs via Stereoselective Polymerization and Tailored Post‐Transformation

Angewandte Chemie, Volume 138, Issue 36, 1 September 2026.
Catalyst‐controlled stereoselective (co)polymerization of functionalized lactones produces vinyl‐, allyl‐, and propargyl‐functionalized PHAs with high syndiotacticity and a broad applicable temperature window, which can be further transformed into crosslinked PHA thermosets, elastic supramolecular networks, and functional grafts. ABSTRACT Incorporation

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Perivascular Matrix Densification Dysregulates Angiogenesis and Activates Pro‐Inflammatory Endothelial Cells

Advanced Science, Volume 13, Issue 49, 3 September 2026.
Perivascular matrix densification promotes the emergence of aberrant endothelial tip cells (ATECs) that invade and persist within fibrotic microenvironments. Using in vivo lineage tracing and a human microvessel model, this study shows that fibrous matrix cues destabilize VE‐cadherin–mediated junctions to gate TGF‐β signaling, inducing a pro ...

The Jekyll and Hyde Nature of Tetrazoles in Polymer Science: From Intrinsic Electronic Duality to Programmable Macromolecular Function

Angewandte Chemie International Edition, Volume 65, Issue 36, 1 September 2026.
Tetrazoles are reframed as substitution‐programmable heterocycles rather than static functional groups in polymer chemistry. By linking electronic identity to synthetic strategy and polymer architecture, this mini‐review establishes a design framework for translating tetrazole duality into predictable macromolecular function.

1,3‐Dipolar Cycloaddition of Nitroalkanes as a Tool of DOS/LOS‐Like Strategy for the Synthesis of Isoxazoles and Isoxazolines

ChemistryEurope, Volume 4, Issue 9, September 2026.
A broadly applicable synthetic platform based on a DOS/LOS‐like strategy is implemented for the case of sp3‐enriched isoxazole/isoxazoline building blocks. The method is based on a [3+2] cycloaddition of nitroalkanes and various alkenes or alkynes. The utility of the proposed approach is illustrated by the discovery of JAK2‐selective inhibitors.
