Cholesterol-PEG-Leucine

Cholesterol-PEG-L-Leucine is a typical amphiphilic polyethylene glycol derivative. It can be used as a carrier material to encapsulate hydrophobic drugs and achieve efficient drug enrichment at the tumor site through the tumor EPR effect. By utilizing the membrane insertion properties of cholesterol, functionalization of liposomes and cell membranes is carried out, introducing leucine related biological recognition sites. It can also be used to construct medical polymer carriers with amino acid responsive properties, supporting research in drug controlled release, protein delivery, and other fields
