DPPE-PEG2000-ANG

DPPE-PEG2000-ANG is composed of three covalently linked components: 1. DPPE (1,2-dipalmitoyl-sn-glycerol-3-phosphoethanolamine): Lipid anchoring group-inserts into the lipid bilayer of liposomes/LNPs, providing stable membrane anchoring; its saturated C16 chain imparts bilayer rigidity. 2. PEG 2000 (polyethylene glycol, molecular weight 2000): Hydrophilic polymer spacer arm-forms a steric hindrance crown around the nanoparticle, reducing opsonin activity and reticuloendothelial system (RES) clearance, prolonging circulating half-life, and providing spatial separation between the lipid surface and the targeting ligand. 3. ANG peptide: Targeting/functional ligand-ANG peptide (Angiopep-2) is a dual-target ligand that binds efficiently to low-density lipoprotein receptor-associated protein 1 (LRP1), mediating the nanocarrier's crossing of the blood-brain barrier (BBB) for targeted delivery to gliomas.
