Series of cationic lipids 1a-p, with variable length of hydrocarbon chains, alternative quaternary ammonium heads, carbamate linkages between hydrocarbon chains and quaternary ammonium heads, as well as different anion combined with them, were synthesized for liposome-mediated gene delivery. Two plasmid DNAs, pGL3-control and pGFP-N2, were transferred by cationic liposomes formed from the above cationic
合成了一系列阳离子脂质1a-p,它们具有可变长度的烃链,交替的季铵头,烃链和季铵头之间的氨基甲酸酯键以及与它们组合的不同阴离子,用于脂质体介导的基因传递。由上述阳离子脂质形成的阳离子脂质体将两个质粒DNA pGL3-control和pGFP-N2转移到五个哺乳动物细胞系中,某些阳离子脂质体的转染效率优于或平行于两种商业转染剂,Lipofectamine2000和Sofast。
