KULL, F. C. (CIBA Pharmaceutical Products Inc., Summit, N. J.), P. C. EISMAN, H. D. SYLWESTROWICZ, AND R. L. MAYER. Mixtures of quaternary ammonium compounds and long-chain fatty acids as antifungal agents. Appl.

A total of 10 cyanogen bromide peptides were isolated from the S-beta-carboxymethyl iron protein of nitrogenase. Purification of these peptides was performed mainly by gel filtration on Sephadex G-50; by ascending paper chromatography using the solvent system of pyridine, isoamyl alcohol, 0.1 M ammonium hydroxide; and also, in some cases, with additional steps such as anion exchange column chro...

In 1916 Jacobs, Heidelberger, and coworkers at the Rockefeller Institute reported the discovery of a new class of synthetic compounds which possessed potent bactelicidal properties. By reacting hexamethylenetetramine with a large variety of substituted benzylor alkyl-halides, nujmerous quaternary salts of this base were obtained. It was observed that most of these salts had pronounced bacterici...

quaternary ammonium compounds (qacs) are employed both as disinfectants for manual processing lines and surfaces in the food industry, and in human medicine area. qacs also cause cell death by protein denaturation . one of the qac is cetyl trimethyl ammonium bromide (ctab) that appears to rapture the cell membrane. the primary site of action of ctab has been suggested to be the lipid components...

Hyoscine-N-butyl bromide is a widely used antispasmodic belonging to the belladonna alkaloid class of semisynthetic quaternary ammonium compounds. These compounds exert a spasmolytic action on the smooth muscles of the bile-gastrointestinal tract, genitourinary tract, salivary glands (xerostomia), and also on the visual apparatus - in particular, the irido-ciliary complex. As a consequence, the...

The effects of the cationic surfactant (cationic cetyl trimethyl ammonium bromide, CTAB) on the improvement of the sludge dewaterability using the cationic flocculant (cationic polyacrylamide, CPAM) were analyzed. Residual turbidity of supernatant, dry solid (DS) content, extracellular polymeric substances (EPS), specific resistance to filtration (SRF), zeta potential, floc size, and settling r...
