DOPE-PEG1000-cRGD

DOPE-PEG1000-cRGD is specifically designed for active targeting nanomedicine applications. It can be incorporated into liposomes, lipid nanoparticles (LNPs), or other nanocarriers to confer ligand-directed targeting capability against αvβ3/αvβ5 integrins on tumor vasculature and cancer cell surfaces.
Composition and role of each component:
1. PEG1000 (polyethylene glycol, MW 1000): Hydrophilic polymer spacer arm that forms a steric corona around nanoparticles, reducing opsonization and reticuloendothelial system (RES) clearance, prolonging circulation half-life, and providing spatial separation between the lipid surface and targeting ligand.
2. cRGD (cyclic RGD peptide (cyclo(Arg-Gly-Asp))): Targeting ligand-a cyclic peptide containing the arginine-glycine-aspartic acid (RGD) motif that selectively binds to αvβ3 and αvβ5 integrins, which are highly expressed on tumor neovasculature, activated endothelial cells, and certain cancer cells.
