unsaturated hydrophobic dioleylglycerol moiety joined together by a linear or a cyclicorthoester linker. At pH 7.4, the lipids formed stable complexes with plasmid DNA together with the conelike helper lipid 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine (DOPE). The decrease of pH enhanced the hydrolysis of the orthoester linkers, which removed the cationic head groups and caused the aggregation of
