The invention provides new lipopolyamines of spermine type of the general formula I, wherein X is C—N bond or aminopolyethyleneglycolcarboxamide linker or o-hydroxy-alkylcarboxamide linker or ω-hydroxyalkylcarboxamidopolyethyleneglycol-carboxamide linker, and wherein a hydrophobic domain Y is an acyl symmetrically branched in the position C(2) or cholesteryl. The invention further provides a method of preparation of said lipopolyamines and their use for construction of polycationic liposomal drug carriers.
该发明提供了一种新的通式I的脂质聚胺,其中X是C—N键或氨基聚乙二醇羧酰胺连接物或o-羟基烷基羧酰胺连接物或ω-羟基烷基羧酰胺聚乙二醇羧酰胺连接物,其中疏水域Y是在位置C(2)处对称分支的酰基或胆固醇。该发明还提供了所述脂质聚胺的制备方法及其用于构建多阳离子脂质体药物载体的用途。
