Click‐Functionalized Cyanine Fluorogenic Dimers for Improved Detection of GPCRs: Application to Imaging of ApelinR in Living Cells

Chemistry – A European Journal, EarlyView.
A click‐mediated functionalization of a cyanine 5.5 bearing a terminal alkyne gave a rapid access to a library of ten new cyanine dyes and their corresponding dimers. A structure‐interaction relationship study led to the identification of an optimal dimer which was conjugated to the apelin‐17 ligand and enabled imaging of ApelinR under no‐wash ...

Conformational Switch in the Alpha‐Synuclein C‐Terminal Domain Directs Its Fibril Polymorphs

Chemistry – A European Journal, EarlyView.
The conformational state of the C‐terminal domain determines the fibril morphology of full‐length wild‐type alpha‐synuclein: high C‐terminus flexibility promotes twisted fibrils, while partial C‐terminal folding drives the assembly of rod‐like fibrils.

Comprehensive Analysis of Crystalline Hydrophobic Alkylated Poly(ethyleneimine)s

Chemistry – A European Journal, EarlyView.
Alkylation of polyethyleneimine (PEI) induces crystalline hydrophobic domains, critical for CO₂‐mediated desalination. Structural evolution during acid/base treatment and ion exchange is revealed by PXRD, SAXS, and inelastic neutron scattering. Findings highlight reversible domain disruption and nanostructure formation, enabling recyclable polymer ...

Copper‐Catalyzed Regioselective Meta C─H Bond Olefination of Anilides

Chemistry – A European Journal, Volume 31, Issue 31, June 3, 2025.
A Copper‐catalyzed meta C─H olefination of pivanilides with β‐styrenyl and β‐alkyl‐alkenyl iodonium salts was achieved using a weakly coordinated directing group (DG). The involvement of a Heck‐like four‐membered transition state was plausibly critical in ensuring the challenging meta selectivity.

Determination of Quaternary Ammonium Compounds

Journal of Pharmaceutical Sciences, 1961
Abstract The official potassium ferricyanide assays of quaternary ammonium, preparations can be modified to include a potentiometric titration with silver nitrate instead of the suggested iodometric method for the determination of the excess ferricyanide. Sodium nitrite interferes with the ferricyanide assay methods.
