DMG-PEG2000-KTP

DMG-PEG2000-KTP is composed of three covalently linked components: 1. DMG (dimyristoylglycerol): Lipid anchoring group-a diacylglycerol with two C14 chains, providing moderate membrane anchorage; its short-chain, high-fluidity characteristics enable faster dissociation of PEG-lipids from nanoparticle surfaces, facilitating endosomal escape and cellular uptake. 2. PEG 2000 (polyethylene glycol, molecular weight 2000): Hydrophilic polymer spacer arm-forms a steric hindrance crown around nanoparticles, reducing opsonin activity and reticuloendothelial system (RES) clearance, prolonging circulating half-life, and providing steric separation between the lipid surface and the targeting ligand. 3. KTP peptide: Targeting/functional ligand-KTP peptide is a kidney-targeting peptide that can directionally deliver carriers to kidney tissue, increasing renal drug accumulation, and simultaneously redirecting carriers originally enriched in the liver to the kidneys.
