Irregular cationic lipotetrapeptides for pharmaceutical multifunctional transport systems

New cationic branched lipotetrapeptides based on l-amino acids and higher alkanols were prepared. Study of their physicochemical and membrane-forming properties revealed that phase transition temperature of these amphiphiles locates in the range of physiological norm. The particle sizes of liposomal dispersions with high aggregation stability are in dimension applicable to penetrate into small blood vessels.
