A biodegradable, novel cationic lipopolymer comprising a branched polyethylenimine(PEI), a cholesterol derived lipid anchor, and a biodegradable linker which covalently links the branched PEI and cholesterol derived lipid anchor. One example of such a novel lipolymer is poly{(ethylene imine)-co-[N-2- aminoethyl) ethylene imine]-co-[N-(N-cholesteryloxycarbonyl-(2- aminoethyl)ethylene imine]}("PEACE"). The cationic lipopolymers in the present invention can be used in drug delivery and are especially useful for delivery of a nucleic acid or any anionic bioactive agent to various organs and tissues after local or systemic administration. Methods of preparing and using the cationic lipopolymer gene carriers of the present invention to efficiently transfect cells, both in vitro and in vivo, are disclosed.

La présente invention concerne un nouveau lipopolymère cationique biodégradable qui comprend une polyéthylènimine (PEI) ramifiée, un site d'ancrage lipidique dérivé de cholestérol, et un lieur biodégradable qui se lie de façon covalente à une PEI ramifiée et à un site d'ancrage lipidique dérivée de cholestérol. La poly{(éthylène imine)-co-[N-2-aminoéthyle) éthylène imine]-co-[N-(N-choléstéryloxycarbonyl-(2-aminoéthyle)éthylène imine]}("PEACE") est un exemple de ce nouveau lipopolymère. Les lipopolymères cationiques de cette invention peuvent être utilisés dans l'apport de médicament et conviennent particulièrement pour l'apport d'acide nucléique ou de n'importe quel agent bioactif anionique à divers organes et tissus après une administration locale ou systémique. Cette invention concerne aussi des procédés de préparation et d'utilisation de ces porteurs de gène lipopolymère cationique permettant de transfecter efficacement des cellules, tant in vitro que in vivo.
