Description

1,2-Distearoyl-sn-glycero-3-phosphoethanolamine (DSPE)-poly(ethylene glycol) with conjugated orthopyridyl disulfide (OPSS or PDP) (DSPE-PEG-OPSS) is a linear heterobifunctional PEGylation reagent with a DSPE phospholipid and a orthopyridyl disulfide. DSPE-PEG-OPSS is an 18 carbon phospholipid PEG conjugate which has both hydrophilicity and hydrophobility, which is a useful self-assembling reagent to prepare PEGylated liposome or micelle while also providing a thiol or cysteine reactive maleimide group. Orthopyridyl disulfide or pyridyldithio functional group can selectively reacts with free thiol, SH, sulfhydryl or mercapto to form a oxidation, reduction reversible disulfide bond. Pegylation of phospholipids significantly improves the blood circulation time and stability for encapsulated drugs.
