Photo-Induced Thermal Crosslinking of Epoxy Compounds by the Use of Quaternary Ammonium Salts Having Phenacyl Groups.

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...

Microwave 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.

Antibacterial 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...
