A cationic amphiphile for facilitating transport of a biologically active molecule into a cell has the structure A-F-D, in which A is a lipid anchor, D is a head group, and F is a spacer group having the structure described herein. A method for facilitating transport of a biologically active molecule into a cell comprises preparing a lipid mixture comprising a cationic amphiphile having structure A-F-D, preparing a lipoplex by contacting the lipid mixture with a biologically active molecule; and contacting the lipoplex with a cell, thereby facilitating transport of the biologically active molecule into the cell.
一种用于促进生物活性分子进入细胞的阳离子两性分子具有结构A-F-D,其中A是脂质锚,D是头基,F是具有所述结构的间隔基团。一种促进生物活性分子进入细胞的方法包括制备包含具有结构A-F-D的阳离子两性分子的脂质混合物,通过将脂质混合物与生物活性分子接触来制备脂质复合物;并将脂质复合物与细胞接触,从而促进生物活性分子进入细胞。
