A Convenient, Safe, and Atom‐Economical Route to a Large Portfolio of Grubbs‐Type Catalysts for Olefin Metathesis via Four‐Coordinate Ruthenium Alkylidynes

Angewandte Chemie, Volume 138, Issue 16, 13 April 2026.
It may seem counterintuitive to first target a ruthenium alkylidyne when Grubbs‐type ruthenium carbene complexes are the actual goal. In the end, however, this tactic pays valuable dividends in terms of practicality, atom economy, flexibility as well as safety: the new route provides ready access to a large assortment of catalysts for alkene metathesis

Betulin Protects Against Cardiac Hypertrophy by Improving AMPK/Nrf2‐Dependent Mitochondrial Function

Phytotherapy Research, Volume 40, Issue 5, Page 2878-2894, May 2026.
Betulin effectively mitigates pressure overload‐induced cardiac hypertrophy in both Ang II‐infused and TAC‐operated mice. Mechanistically, betulin activated AMPK phosphorylation, promoted Nrf2 nuclear translocation, and upregulated antioxidant genes (HO‐1 and NQO‐1), thereby restoring mitochondrial function in cardiomyocytes.

Equipped for success: genomes and metabolomes of the European Amanita muscaria are conserved in its novel South African range

New Phytologist, Volume 250, Issue 3, Page 1863-1883, May 2026.
Summary Plants and soils have been moved around the world for centuries, but invasive mushrooms receive scant attention. The Amanita muscaria species complex was introduced to South Africa in the context of forestry, but its origins, ecology and recent evolution are unstudied. We sequenced the genomes of 24 Northern and Southern Hemisphere A. muscaria,

Design, Synthesis, and Evaluation of New Polyhydroxylated Bis‐Chalcones as Potential COX‐2 Selective Inhibitors

ChemMedChem, Volume 21, Issue 8, 28 April 2026.
Novel polyhydroxylated bis‐chalcones were successfully synthesized and demonstrated COX‐2 selective inhibition. The most potent and selective inhibitor exhibited a mixed‐type inhibition mechanism with COX‐2. Its additional bulk preferentially blocked the access to the active pocket of COX‐1 rather than COX‐2. Selective inhibition of COX‐2 is considered

Recent Developments in Sustainable Solubilization

ChemSusChem, Volume 19, Issue 8, 28 April 2026.
We highlight several recent developments in sustainable solubilization. Particular attention is given to the use of bio‐based solvents derived from renewable resources, the strategic use of water as a solvent, and alternative, sustainable solubilizers such as hydrotropes.

Molecular Engineering of the Helminth TGF‐β Mimetics, TGM1 and TGM4, Reveals a Novel Antagonist of TGF‐β Signaling in Fibroblasts

The FASEB Journal, Volume 40, Issue 7, 15 April 2026.
The helminth TGF‐β mimic TGM4 activates SMAD signaling in macrophages and T cells through canonical TGF‐β receptors and the CD44 co‐receptor, through Domains 1–5 (D1‐5). In fibroblasts, which express lower levels of CD44, TGM4 binds but does not transduce a signal; furthermore, it inhibits activation by agonist ligands such as TGF‐β itself, in a manner
