1-Palmitoyl-2-succinyl-sn-glycerophosphorylcholine, a glycerophosphorylcholine derivative, comprises glycerol phosphate, choline, and palmitic acid and accumulates at oxidative stress sites in vivo. It potentially acts as a ligand for scavenger receptors class B, akin to oxidized phospholipids oxPC(CD36), which are established potent ligands for receptors CD36 and SR-BI. These oxidized phospholipids also play a pivotal role in promoting tumor apoptosis and may present in higher concentrations within malignant biliary strictures [1] [2].
