DSPE-PEG(2000)-amine is the amine derivative of phospholipid poly ethylene glycol with biocompatible and biodegradable properties [1]. DSPE-PEG(2000)-amine can be used to encapsulate liposomes and facilitate the passage of liposomes through the blood-brain barrier[2]. DSPE-PEG(2000)-amine can self-assemble into micelles and are easily modified, which participates in lipid transfer to design targeted liposomes, thereby protecting the targeting ligands during circulation[3]. DSPE-PEG(2000)-amine has been widely used in the preparation of liposomes and polymer nanoparticles to reduce the in vivo clearance rate and plasma protein adsorption of cholesterol-free lipid formulations, prolong the in vivo circulation time, increase targeting ability and improve bioavailability[4].

DSPE-PEG(2000)-amine是一种具有生物相容性和可生物降解性的磷脂-聚乙二醇胺衍生物[2]。DSPE-PEG(2000)-amine可用于包封脂质体,并促进脂质体通过血脑屏障[2]。DSPE-PEG(2000)-amine可自组装形成胶束,且易于修饰,参与脂质转移以设计靶向脂质体,从而在循环过程中保护靶向配体[3]。DSPE-PEG(2000)-amine已被广泛用于制备脂质体和聚合物纳米颗粒,以降低无胆固醇脂质制剂的体内清除率和血浆蛋白吸附,延长体内循环时间,增加靶向能力并提高生物利用度[4]。
