| Abstract: | Two new families of cationic lipids were designed and synthesized for gene delivery, namely "lipophosphoramidates" and "lipophosphoguanidines", whose efficiency was noteworthy. The most efficient have an arsonium cation as the polar head, and the unsaturated lipidic tails (e.g. oleyl) gave the better in vivo results (mice lungs). |
