PS-PEG 是一种磷脂 - 聚乙二醇偶联物,兼具亲水性与疏水性。聚乙二醇化磷脂是性能优异的脂质体制备材料,可用于药物递送、基因转染及疫苗递送。磷脂经聚乙二醇修饰(PEG 化)后,可显著提升包载药物的体内血液循环时间与稳定性。该类材料还可通过在表面修饰抗体、多肽等靶向配体,实现靶向药物递送。
3-sn-Phosphatidyl-L-serine (PS) conjugated Polyethylene Glycol, PS PEG is a phospholipid PEG conjugate which has both hydrophilicity and hydrophobility. Pegylated phospholipids are excellent liposome formation materials that can be used for drug delivery, gene transfection and vaccine delivery as well. Pegylation of phospholipids significantly improves the blood circulation time and stability for encapsulated drugs. These materials can also be used for targeted drug delivery by modifying their surfaces with targeting ligands such as antibodies, peptides.
