ABSTRACT:
The present invention relates to piperazine based amphilic cationic lipids useful for gene therapy, transfection, and introducing immunogenic compounds for the purpose of vaccination. The disclosed compounds have lipophilic moieties linked to the ring nitrogens. In addition, at least one of the ring nitrogens is quatranized and linked to a hydrocarbon having at least one heteroatom.
