Application

β-Acetyl-γ-O-hexadecyl-L-α-phosphatidylcholine has been used:
  • to study its effects on phagocytic activity and production of superoxide anion in equine alveolar macrophage and blood neutrophils
  • to study its protective effects against cisplatin-induced cell death in a human melanoma cell line in vitro
  • to determine its effects on cervical ripening and leukocyte infiltration in rat models

Biochem/physiol Actions

β-Acetyl-γ-O-hexadecyl-L-α-phosphatidylcholine or platelet-activating factor (PAF), is a phospholipid, and a pro-inflammatory lipid mediator. It acts as a ligand for G protein-coupled platelet-activating factor (PAF) receptors and participates in several biological processes such as airway constriction, hypotension, platelet activation, and increased vascular permeability. PAF is released by various cells such as platelets, neutrophils, endothelial cells, and monocytes/macrophages. The levels of PAF are low in the blood due to its rapid metabolism by PAF acetylhydrolase and low production.

Platelet-activating factor (PAF) is an early product of the inflammatory environment, influencing development and resolution of inflammation. Its production is greater in neutrophils and macrophages, which predominantly synthesize 1-alkyl sn-2 acetyl glycerophosphocholine (GPC) than in nongranulocytes (B cells and endothelial

Alkyl-PAF induced two components of polymorphonuclear leukocyte (PMN) priming for enhanced fMLP- and rC5a-induced superoxide anion (O2-) production. Component A priming had a shallow, linear alkyl-PAF concentration-response slope (10 pM-1 nM), and component B priming had a significantly steeper concentration-response
