Inactivation of the Germicidal Action of Quaternary Ammonium Compounds*
Journal of the American Pharmaceutical Association (Scientific ed.), 1948Abstract The need for means of inactivating the anti‐bacterial activity of quaternary ammonium germicides is summarized. Anionic detergents and soaps fail to inactivate surface‐active cationic detergents. Suramin sodium is the most satisfactory inactivator of any in a group of sulfonates and sulfonic acids tested for this purpose.

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.
