non-viral gene delivery. A long aliphatic chain (C22-C24) was introduced at the 1-position of glycerol backbone, a branched lipid chain (C18) at the 2-position, and a phosphocholine head group at the 3-position. The fusogenicity of APC depends on the length and degree of saturation of the alkyl chain. Cationic lipids were formulated with APC as either lipoplexes or nanolipoparticles, and evaluated for their
合成了合理设计的不对称烷基酰基
磷脂酰
胆碱(APC),并作为非病毒
基因传递的辅助脂质进行了评估。在
甘油骨架的1位上引入了长脂肪链(C22-C24),在2位上引入了分支脂质链(C18),在3位上引入了
磷酸胆碱头基。APC的融合性取决于烷基链的长度和饱和度。阳离子脂质与APC配制成脂质体或纳米脂质体,并评估其稳定性,转染效率和细胞毒性。APC介导高的体外转染效率,并具有较低的细胞毒性。通过使用低至0.1%的P
EG-脂质,可以用APC获得小的纳米脂质颗粒(小于100 nm)。
