Newlipophilic polyamines in which natural or synthetic tetraamines were linked via the terminal NH2 groups to diglycerides and/or to short-chained aliphatic substituents were synthesized, and their cytotoxicactivity was tested. Relationship between the structure of the synthesized compounds and their cytotoxicity and hemolytic effect was evaluated.

properties and transfection efficiencies. Cationic liposomes formed by these amphiphiles and the helper lipid DOPE were able to successfully condense DNA, as shown by gel mobility shift and ethidium bromide intercalation assays. Transfection activity of the liposomes was superior to Lipofectamine® 2000 and was dependent on spacer structure, hydrophobicity, and nucleic acid type (pDNA or siRNA). We demonstrated
