Diarylethene‐Containing Photoswitchable Analogues of Tubulysins—Design, Synthesis, Biological, and Structural Evaluation

European Journal of Organic Chemistry, EarlyView.
Diarylethene‐containing cyclic tubulysin analogues were designed, synthesized, and evaluated as light‐responsive cytotoxic agents. One analogue showed reversible photoswitching, photoregulated tubulin polymerization inhibition, and photoform‐dependent cytotoxicity.

Boronic Acid Inhibitors of β‐Lactamases: A Promising Strategy Against Antimicrobial Resistance

Medicinal Research Reviews, EarlyView.
ABSTRACT The rise of antimicrobial resistance (AMR) poses a critical threat to global health, mostly due to the proliferation of β‐lactamases, a class of enzymes responsible for the inactivation of β‐lactam antibiotics. Among the most promising strategies to restore β‐lactam efficacy is the use of β‐lactamase inhibitors (BLIs), with boronic acid ...

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

Synthesis and Reactivity of 3-Aminosydnones in Cycloaddition Reactions With Alkynes. [PDF]

Chemistry
The synthesis, functionalization, and reactivity as dipoles of 3‐aminosydnones have been investigated. These neglected compounds undergo smooth cycloaddition reactions with strained alkynes, leading to 1‐aminopyrazoles. ABSTRACT We present in this article the synthesis, functionalization, and properties of 3‐aminosydnones, a forgotten class of ...

Oxadiazolone‐Triazole Derivatives as a New Scaffold for Modulation of Angiotensin II‐Induced Vascular Contraction

ChemMedChem, Volume 21, Issue 17, 14 September 2026.
A novel series of candidate AT1 receptor antagonists based on oxadiazolone‐triazole scaffolds was designed and synthesized. Most compounds reduced angiotensin II‐induced vascular contraction in an initial biological screening, with compound 7f emerging as the most active derivative.

Precision Chemistry for Protein Lysine Modification

Chemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.
Selective modification of lysine residues is challenging due to their similar intrinsic reactivity. Inspired by enzymatic recognition, ligand‐guided electrophiles enable site‐selective labeling and functionalization, while ligand‐guided catalyses achieve regioselective installation of bio‐relevant post‐translational modifications.
