Von Richter Cinnolines Synthesis Revisited—Approach to Polysubstituted Cinnoline Derivatives as Important Scaffolds for Kinase Inhibitors

open access: yesChemistrySelect, Volume 11, Issue 29, 3 August 2026.
A revised von Richter cyclization of 2‐aminoalkyne precursors enables the synthesis of polysubstituted 4‐halocinnoline derivatives. By addressing the key challenge of hydrolytic instability, this catalyst‐free approach delivers scaffolds amenable to late‐stage C‐4 functionalization.

Shared and specific molecular mechanisms of proteasome inhibitors in chemotherapy‐induced peripheral neurotoxicity

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 16, Page 5120-5147, August 2026.
This study compares the molecular mechanisms of chemotherapy‐related peripheral neurotoxicity of two proteasome inhibitors, bortezomib and carfilzomib, using a multidisciplinary approach to reveal that, alongside shared effects on mitochondria structure and function, the more neurotoxic drug BTZ has specific effects on microtubules and mitochondrial ...

ERF transcription factor StPti5 is a regulator of endophyte community maintenance in potato

open access: yesNew Phytologist, Volume 251, Issue 3, Page 1344-1360, August 2026.
Summary We have recently identified an ethylene response factor, StPti5, as a susceptibility factor that negatively regulates immune responses to diverse pathogens. Here, we investigated the role of StPti5 in the processes involved in the colonization of potato with beneficial organisms.

Acyclic Hydrocarbon α,ω‐Dienes: From Biomass and Plastic Upcycling to Carbocycles, Precision Polymers, and Cross‐Linked Elastomers

open access: yesChemSusChem, Volume 19, Issue 14, 29 July 2026.
Hydrocarbon α,ω‐dienes are mainly produced from steam‐cracking derivatives, but high costs, complexity, and environmental impact limit their use. This review highlights sustainable paths from biomass and plastic upcycling, and surveys catalytic transformations into carbocycles and specialty polymers, emphasizing their role as modular building blocks ...

Dilithium Enediamide Derived From 1,4‐Diaza‐1,3‐Diene: An Electron Reservoir Enabling Variable Reactivity Toward Carbonyl Compounds

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 21, 25 July 2026.
Upon reduction of 1,4‐diaza‐1,3‐diene 1 to the dilithium enediamide 2, the polarity of the C = N bonds is reversed ‐ a classic case of umpolung. This behavior is particularly evident in reactions of the dianion 2 with carbonyl compounds and also explains why 1,4‐diaza‐1,3‐diene ligands do not always act merely as spectator ligands. 1,4‐Diaza‐1,3‐dienes
