How eriophyid mites shape metal metabolism in leaf galls on Tilia cordata

New Phytologist, Volume 246, Issue 5, Page 2222-2242, June 2025.
Summary Metal metabolism in plant–galler interactions is largely unknown. We hypothesise that the mites manipulate metal distribution by sequestration of excessive levels and differential regulation of metalloproteins to support the main functions of gall‐nutrition, protection and microenvironment.

Systematic Review on 1,2,3‐Oxadiazoles, 1,2,4‐Oxadiazoles, and 1,2,5‐Oxadiazoles in the Antimycobacterial Drug Discovery

ChemMedChem, Volume 20, Issue 9, May 5, 2025.
The review focuses on relationships of oxadiazole derivative structures and their antimycobacterial activity including target structures in mycobacteria, in vitro or in vivo pharmacokinetic parameters, and toxicity. Apart from direct antimycobacterial activity, some 1,2,4‐oxadiazole derivatives can potentiate the antimycobacterial effect of ethionamide

Design and Synthesis of Tetrahydropyrrolo[3,4‐c]Pyrazole Sigma‐1 Receptor Ligands

ChemMedChem, Volume 20, Issue 9, May 5, 2025.
This study highlights the tetrahydropyrrolo[3,4‐c]pyrazole scaffold as a promising platform for S1R ligands development. Key findings include compound 19’s high S1R affinity (Ki=75 nM), influenced by strategic nitrogen substitutions and reduced steric hindrance.

Enzymatic Production of Opine‐Type Chiral Amines with Controlled Stereoselectivity

ChemCatChem, Volume 17, Issue 9, May 8, 2025.
The remarkable behavior of a ketimine reductase to enable control over the newly formed stereocenter in the reductive amination between α‐keto acids and α‐amino esters is reported. Mechanistic understanding for this unique property is provided at the molecular level within the enzyme active site.
