Reaction of a Pyridinium Salt with N,N-Dimethylhydrazine.

Synthesis and characterizations of pyridinium salts including poly(pyridinium salt)s and their applications

Antibacterial activity and characteristics of modified ferrite powder coated with a gemini pyridinium salt molecule.

This report describes the synthesis of an antibacterial material consisting of a gemini quaternary ammonium salt (gemini-QUAT) immobilized on ferrite powder, and its antibacterial activity. A gemini-QUAT containing two pyridinium residues per molecule, 4,4'-[1,3-(2,2-dihydroxylmethyl-1,3-dithiapropane)]bis (1-octylpyridinium bromide), was immobilized on ferrite powder by a reaction between the ...

Development of a novel, multifunctional, membrane-interactive pyridinium salt with potent anticancer activity.

The synthesis and biological evaluation of a novel pyridinium salt is reported. Initial membrane interaction with isolated phospholipid monolayers was obtained with the pyridinium salt, and two neutral analogues for comparison, and the anticancer effects of the best compound established using a cytotoxicity screening assay against glioma cells using both an established cell line and three short...

Pyridinium Salts, Insertion Reaction, Oximes Pyridinium Salts with electron-withdrawing groups in the 3-position react with aliphatic ketoximes

Die Anlagerung von Nucleophilen an quartäre Pyridinium-Salze ist seit langem bekannt [2], ebenso die Beobachtung, daß Ringöffnungsund Umlagerungsreakt ionen sich anschließen können, gerade bei der Einwirkung von z.B. Hydroxidoder Alkoxid-Ionen und Aminen [3, 4]. Quartäre Salze von Pyridincarbaldoximen, die ausgeprägt hydrophile Eigenschaf ten haben, werden als Reaktivatoren bei In toxika t ion ...

Synthesis and crystal structure of a new pyridinium bromide salt: 4-methyl-1-(3-phen­oxy­prop­yl)pyridinium bromide

In the cation of the title mol-ecular salt, C15H18NO+·Br-, the pyridinium and phenyl rings are inclined to one another by 11.80 (8)°. In the crystal, the Br- anion is linked to the cation by a C-H⋯Br hydrogen bond. The cations stack along the b-axis direction and are linked by further C-H⋯Br inter-actions, and offset π-π inter-actions [inter-centroid distances = 3.5733 (19) and 3.8457 (19) Å], ...
