  An Epoxyisoprostane Is a Major Regulator of Endothelial Cell Function

  摘要：

  The goal of these studies was to determine the effect of 5,6-epoxyisoprostane, El, on human aortic endothelial cells (HAEC). El can form as a phospholipase product of 1-palmitoyl-2-(5,6-epoxyisoprostane E2)-sn-glycero-3-phosphocholine, PEIPC, a proinflammatory molecule that accumulates in sites of inflammation where phospholipases are also increased. To determine the effect of El on HAEC, we synthesized several stereoisomers of El using a convergent approach from the individual optically pure building blocks, the epoxyaldehydes 5 and 6 and the bromoenones 14 and 16. The desired stereoisomer of El can be prepared from these materials in only six operations, and thus, large amounts of the product can be obtained. The trans/trans isomers had the most potent activity, suggesting specificity in the interaction of El with the cell surface. El has potent anti-inflammatory effects in HAEC. El strongly inhibits the production of MCP-1, a major monocyte chemotactic factor, and either decreases or minimally increases the levels of 10 proinflammatory molecules increased by PEIPC. El also strongly down-regulates the inflammatory effects of IL-1 beta, a major inflammatory cytokine. Thus El, a hydrolytic product of PEIPC, has potent anti-inflammatory function.
