development of alternative molecular structures for gene transfer holds key to the discovery of new potent nonviral gene delivery vehicles.For instance, the transfection properties of a few cationic lipids based on aromatic backbone have been reported. Hoekstra et al. described the gene delivery properties of certain pyridinium surfactants. Balaban and co-workers investigated the transfection properties of various cationic lipids based on pyridinium, dimeric, and oligomeric surfactans having structural variations at the level of hydrophobic segment, linker, and counterions. Safinya and co-workers have shown that multivalent cationic lipids with an aromatic hold a promise for superior gene transfections activities. Cationic lipid (TRX) having an amidine group with an aromatic backbone coupled with dodecyl hydrocarbon chains have developed by Sakurai and coworkers. Recently, Phanstiel and co-workers disclosed the transfection properties of certain lipophilic polyamines.
