A liposome having a lipid bilayer, where the lipid bilayer includes either the L or D stereoisomer of an ether lipid or a non-equal mixture of both. Most preferably the liposome also comprises (a) an underivatized phosphatidylcholine; (b) a sterol; (c) about 5-20 mole % of a phosphatidylethanolamine linked to a dicarboxylic acid at the ethanolamine group of the phosphatidylethanolamine, and (d) greater than about 10 mole % to less than about 30 mole % of either the L or D stereoisomer of an ether lipid. The liposome may be used as an anti-cancer or anti-inflammatory agent.
一个具有脂质双分子层的脂质体,其中脂质双分子层包括醚脂类的L或D立体异构体之一或两者的非等量混合物。最好的情况是,脂质体还包括(a)未衍生的磷脂酰胆碱;(b)一种固醇;(c)约5-20摩尔%的磷脂醇胺与磷脂醇胺的乙醇胺基团上连接有二羧酸的酯化羧基,以及(d)大约10摩尔%以上但小于30摩尔%的醚脂类的L或D立体异构体。该脂质体可用作抗癌或抗炎药剂。
