Abstract: Previous studies demonstrated that oxidized 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphorylcholine inhibits inflammatory effects of the bacterial lipopolisacharide (LPS, endotoxin). In this work we have characterized the anti-endotoxin activity of other classes of oxidized phospholipids with different polar head groups and fatty acid residues. LPS-induced expression of E-selectin on human endothelial cells was inhibited by oxidized phosphatidylcholine, phosphatidylserine, phosphatidylethanolamine, and phosphatidic acids. The anti-endotoxin effect insignificantly depended on the type of polyunsaturated fatty acids. Unoxidized phospholipids did not suppress effects of LPS. Thus, the anti-endotoxin activity of oxidized phospholipids crucially depends on the presence of oxidatively modified fatty acid residue.
