The instant invention provides for novel cationic lipids that can be used in combination with other lipid components such as cholesterol and PEG-lipids to form lipid nanoparticles with siRNA, to facilitate the cellular uptake and endosomal escape, and to knockdown target mRNA both in vitro and in vivo.
本发明提供了一种新型阳离子脂质,可以与其他脂质成分(如
胆固醇和P
EG脂质)结合使用,形成含有siRNA的脂质纳米粒子,以促进细胞摄取和内体逃逸,并在体外和体内靶向mRNA进行靶向RNA干扰。
