Novel cationic cholesterol derivatives with ether and ester linkages between cationic head group and cholesterol backbone have been developed. Their gene transfection efficacies have been tested as mixtures with a helper lipid, dioleoyl phosphatidyl ethanolamine (DOPE). It has been observed that there is an improvement in gene transfection efficacies when cationic head group is linked to cholesterol via an ether type of linkage.
