Abstract: Lipopeptides on the basis of L-glutamic acid and glutamine di- and monoesters with aliphatic alcohols of various lengths that contain L-arginine, L-ornithine, and L-lysine were synthesized. The behavior of these amphiphiles in aqueous medium was shown to depend on their structure.

Key words: cationic amphiphiles, lipopeptides, delivery systems
