Sustainable triazine-derived quaternary ammonium salts as antimicrobial agents.

The first examples of highly efficient antimicrobial triazine-derived bis imidazolium quaternary ammonium salts (TQAS) are reported. TQAS have been prepared with an easy, atom efficient, economically sustainable strategy and tested as antimicrobial agents, reaching MIC values below 10 mg L-1. Distinctively, TQAS have low MIC and low cytotoxicity.
