title: Novel non-viral vectors for gene delivery: synthesis of a second-generation library of mono-functionalized poly-(guanidinium)amines and their introduction into cationic lipids.
abstract: The development of new gene delivery technologies is a prerequisite towards gene therapy clinical trials. Because gene delivery mediated by viral vectors remains of limited scope due to immunological and propagation risks, the development of new non-viral gene delivery systems is of crucial importance. We have synthesized a secondary library of mono-functionalized poly-(guanidinium)amines generated from a library of mono-functionalized polyamines applying the concept of "libraries from libraries." The method allows a quick and easy access to mono-functionalized geometrically varied poly-(guanidinium)amines. The new building blocks were introduced into cationic lipids to obtain novel poly-(guanidinium)amine lipids, which are potential DNA vectors for gene delivery.
