ChemMedChem, Volume 21, Issue 16, 27 August 2026.Proline‐derived Au(I)–NHC complexes display potent anticancer activity against lung and triple‐negative breast cancer cells. The cationic complexes promote DNA intercalation, thioredoxin reductase inhibition, ROS overproduction, and mitochondrial membrane depolarization, ultimately triggering apoptotic cell death through a multimodal mechanism of ...

ChemistryEurope, Volume 4, Issue 8, August 2026.A new family of pentamethylcyclopentadienyl (C5Me5, Cp*) iridium(III), rhodium(III), and ruthenium(III) complexes bearing bidentate 1,2‐dioxime ligands was developed and their catalytic performances were evaluated in the hydrogen‐borrowing‐type H/D exchange of amines using D2O as both solvent and deuterium source. Iridium derivatives achieved excellent

Polyesterase activity and thermostability of carboxylesterases from Thermoleophilum album YS‐3
The FEBS Journal, Volume 293, Issue 15, Page 4724-4743, August 2026.Three novel α/β‐hydrolases from thermophilic bacterium Thermoleophilum album display carboxylesterase and polyesterase activity. These enzymes hydrolyse PET, PLA and PCL both at high and moderate temperatures. TA21 shows superior activity, efficiently converting MHET to terephthalic acid. Structural features underlying substrate binding highlight their

ChemBioChem, Volume 27, Issue 14, 29 July 2026.5‐Keto‐4‐deoxy glucarate dehydratase and 2‐keto‐3‐deoxy‐L‐arabinonate dehydratase share many similarities like structure, reaction mechanism, and their generated product, but exhibit very high substrate specificity. Here, we explore the evolutionary development of this specificity in the context of the enzyme superfamily and attempt to find promiscuous
