DSPE-PEG2000-GALA
DSPE-PEG2000-GALA is a PEG compound which composed of DSPE and a lung endothelium-targeting peptide GALA (HY-P5423). GALA is a pH-responsive amphipathic peptide consisting of 30 amino acids, which acts as a lung endothelium-targeting ligand. GALA undergoes a conformational transition from random coil to α-helix in an acidic environment at pH 5.0, thereby inducing endosomal membrane destabilization and fusion. GALA-modified liposomes traverse lung endothelial cells via clathrin-dependent endocytosis and transcytosis, and specifically accumulate in the lungs after intravenous injection. DSPE-PEG2000-GALA can be used for drug delivery.

Biological Activity
Lipids used to prepare nanoparticles are a class of amphiphilic biomolecules that combine structural diversity, biocompatibility, and functional tunability. As the core framework of nanodelivery systems, they not only form lipid bilayers or solid matrices through self-assembly to encapsulate lipophilic or hydrophilic drugs, but can also be further subdivided according to formulation requirements into structural lipids (such as phospholipids and triglycerides), functional lipids (such as ionizable cationic lipids used for nucleic acid condensation and endosome escape), and sterically stable lipids (such as PEGylated lipids).
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
