DSPE-PEG-N3 is a click chemical PEG reagent. Azide group is easy to react with alkynyl group under the catalysis of copper catalyst. It can also react directly with DBCO without any catalyst. DSPE (1,2-distearoyl-sn-glycerol-3-phosphoethanolamine) is a saturated 18 carbon phospholipid, which is commonly used in the synthesis of liposomes. Polyethylene glycol (PEG) - coupled DSPE is hydrophilic and can be used for drug delivery, gene transfection and biomolecular modification. The PEG of phospholipid significantly improved the blood circulation time and stability of the capsule drug. Polyethylene glycol can enhance the solubility and stability, reduce the non-specific binding of charged molecules on the surface, and reduce the immunogenicity of polypeptides.
Azide (- N3) can react with copper catalyzed alkynes in aqueous solution and be reduced to amino groups. Polyethylene glycol can increase solubility and stability. It can also inhibit the nonspecific binding of charged molecules on the modified surface.
