Abstract

Novel lipids for forming liposomes for use as nucleic acid delivery vehicles, e.g. for gene therapy, have structure with a steroid (cholesteryl) domain linked via a carbamoyl linkage to a head group which is positively charged in use (generally through protonation). The head group preferably comprises a nitrogen heterocycle, e.g. a piperazine or morpholine ring system.
