    摘要: Lipid assemblies, such as liposomes, comprising transfection enhancer elements (TEE's), which are complexed with the lipid assemblies by means of ionic interactions, or lipids incorporating such TEE's are disclosed for enhancing the fusogenicity of the lipid assemblies. The TEE's have the formula: hydrophobic moiety-pH sensitive hydrophilic moiety  (II) The pH sensitive hydrophilic moiety of each TEE is a weak acid having a pka of between 2 and 6 or a zwitterionic structure comprising a combination of acidic groups with weak bases having a pKa of between 3 and 8. Lipids incorporating one or more such TEEs have the formula (I): Lipid moiety-[Hydrophobic moiety-pH sensitive hydrophilic moiety]  (I)

    摘要: A method for preparing amphoteric liposomes loaded with polyanionic active agent as cargo, characterised by admixing an aqueous solution of said polyanionic active agent and an alcoholic solution of one or more amphiphiles and buffering said admixture to an acidic pH, said one or more amphiphiles being susceptible of forming amphoteric liposomes at said acidic pH, thereby to form such amphoteric liposomes in suspension encapsulating said active agent under conditions such that said liposomes form aggregates, and thereafter treating said suspension to dissociate said aggregates. Also disclosed are nucleic acid loaded amphoteric liposomes produced in accordance with the method, wherein said nucleic acids are oligonucleotides and said liposomes are multilamellar.
