Inclusion of Quaternary Ammonium Compounds by Calixarenes
Journal of Inclusion Phenomena and Molecular Recognition in Chemistry, 1994In weakly polar solvents, strong association occurs between calixarene anions and tetraalkylammonium cations, with the magnitude of the observed equilibrium constants depending upon the charge on the anion, the solvent, the ring size of the calixarene and the nature of the alkyl group of the cation. Large upfield shifts of the methyl resonances of the [

New Quaternary Ammonium Compounds with Adrenomimetic Action
Science, 1960Quaternary salts of two triesters of p -dimethylaminothiophenol and phosphoric acid or thiophosphoric acid have effects similar to epinephrine on blood pressure, heart rate, and the nictitating membrane of the anesthetized cat. Two analogous compounds derived from phenol are depressor.

Virucidal activity of some quaternary ammonium compounds.
Arzneimittel-Forschung, 1978Four different quaternary ammonium compounds were tested by microtechniques for evaluating their activity against the type species of six viral groups very frequently involved in human and animal pathology. Three disinfectants showed good activity against five of the representative viruses under test, while the fourth proved less effective.
