Synthesis of diether-linked cationic lipids for gene delivery

Article abstract of DOI:10.1016/S0960-894X(99)00187-0

Quaternary ammonium lipids 1b-d, with diether linkages between hydrocarbon chains and butane or hexane backbone, were synthesized for cationic liposome-mediated gene delivery. The synthetic strategy of using C- 4 or C-6 synthon permits the achievement of the variation of the hydrophobic domain as well as changes of space between the quaternary ammonium head and the hydrophobic domain in the diether-linked cationic lipids.
