DSPE-SS-PEG-Serine

DSPE-SS-PEG2k-Serine,The hydrophobic double chain of DSPE can be embedded into the core of liposomes or nanoparticles,while PEG provides a hydrophilic shell,allowing the entire molecule to spontaneously form stable micelle or liposome structures in the aqueous phase.The disulfide bond(SS)in the middle can be broken in the reducing environment of high concentration glutathione(GSH)in cells,achieving targeted drug release in tumor cells,improving treatment efficiency and reducing systemic toxicity. Serine contains -OH and -NH2 functional groups at the end,which exhibit excellent chemical reactivity and can be used for further coupling of targeted molecules.
