A cationic amphiphile for facilitating transport of a biologically active molecule into a cell has the structure A-F-D, in which A is a lipid anchor, D is a head group, and F is a spacer group having the structure described herein. A method for facilitating transport of a biologically active molecule into a cell comprises preparing a lipid mixture comprising a cationic amphiphile having structure A-F-D, preparing a lipoplex by contacting the lipid mixture with a biologically active molecule; and contacting the lipoplex with a cell, thereby facilitating transport of the biologically active molecule into the cell.

The invention provides new lipopolyamines of spermine type of the general formula I, wherein X is C-N bond or aminopolyethyleneglycolcarboxamide linker or o-hydroxy- alkylcarboxamide linker or ω-hydroxyalkylcarboxamidopolyethyleneglycol- carboxamide linker, and wherein a hydrophobic domain Y is an acyl symmetrically branched in the position C(2) or cholesteryl. The invention further provides a method of preparation of said lipopolyamines and their use for construction of polycationic liposomal drug carriers.
The present invention provides cationic lipids with serine backbone, a composition for transferring biologically active molecules into cells and/or tissues comprising said cationic lipids, a process for the manufacture of said lipids, the use of said lipids as constituent of a transfection agent and a method for transferring biologically active molecules into cells and/or into tissues or for gene therapy.
