  • Cationic amphiphiles for liposomal gene transfer
    Patent number: 6489495
    Abstract: This invention relates to the synthesis of novel cationic, amphiphilic lipids and their application as gene transfer vehicles in vitro and in vivo. For this a series of different lipids (diglycerides, steroids) were synthesized by modification with variable cationic molecules (amino acids, biogenic amines). Compounds of this kind are, due to their capability of producing complexes with polynucleotides (DNA, RNA, Antisense oligonucleotides, ribozymes etc) suitable as vectors for gene transfer (transfection).
    Type: Grant
