1,2-Dilinoleoyl-sn-glycero-3-phospho-L-serine (sodium)

1,2-Dilinoleoyl-sn-glycero-3-phospho-L-serine sodium (18:2 PS sodium) is a lipid compound that can be used for liposome preparation. Liposomes are the main component of vesicles with concentric phospholipid bilayer membranes, which can be used to construct drug delivery systems for anti-cancer and anti-infection fields. Highly polar water-soluble loads can be captured in the internal aqueous space of liposomes, while lipophilic loads can be distributed into the lipid bilayer and become part of the lipid bilayer. Especially for the delivery of antisense oligonucleotides, it can overcome the problems of inefficient cellular uptake and rapid loss in the body.
