Quaternary ammonium amalgams as Zintl ion salts and their use in the synthesis of novel quaternary ammonium salts.
dodecapeptide 5 does not seem to follow this trend, which may suggest that secondary interactions exist between the terpenoid and peptide moieties. Although we still need to perform many experiments to develop a reliable mechanistic model to explain the observed phenomenon, our preliminary observations show an interesting potential in this area and investigation along this line is in progress i...
متن کاملMicrowave synthesis of quaternary ammonium salts.
The microwave synthesis of several quaternary ammonium salts is described. The synthesis provides comparable or better yields than published methods with reduced reaction times and in the absence of solvent.
متن کاملInteractions of Quaternary Ammonium Compounds and Proteins
A simple met.hod of titration with a cationic detergent has been developed which permits rapid estimation of the concentration of urinary protein with a minimum of manipulations and time. The method depends on the formation of an insoluble anion-cation complex between quaternary ammonium ions, hereinafter referred to as the cationic detergent, and proteins, in the present instance mainly human ...
متن کاملAntibacterial activity of gemini quaternary ammonium salts.
A series of gemini quaternary ammonium salts (chlorides and bromides), with various hydrocarbon chain and spacer lengths, were tested. These compounds exhibited antibacterial activity against both Gram-positive and Gram-negative bacteria and were not mutagenic. The strongest antibacterial effect was observed for TMPG-10 Cl (against Pseudomonas aeruginosa ATCC 27853) and TMPG-12 Br (against Stap...
متن کامل[Quaternary ammonium compounds--new occupational hazards].
Quaternary ammonium compounds (QACs, quats) belong to organic ionic chemical agents which display unique properties of both surfactants and disinfectants. Their wide distribution in the work environment and also in private households brings about new occupational hazards. This paper reviews reports about the health effects of QACs. QACs could play a role of sensitizers and irritants to the skin...
