  Eicosapentaenoic-acid-derived isoprostanes: Synthesis and discovery of two major isoprostanes

  摘要：

  The stereospecific synthesis of two all-syn-EPA-derived isoprostanes (iPs), 5-epi-8,12-iso-iPF(3 alpha)-VI 17 and 8,12-iso-iPF(3 alpha)-VI 18, has been accomplished. These two synthetic probes have been used to discover and identify their presence in human urine. The eventual quantitative measurement of these two iPs may be a valuable index of oxidative stress in people with eicosapentaenoic acid-(EPA) and docosahexaenoic acid-(DHA) enriched phospholipids.

• A new approach to the synthesis of polyunsaturated deuterated isoprostanes: Total synthesis of d4-5-epi-8,12-iso-iPF3α-VI and d4-8,12-iso-iPF3α-VI

  The total and stereospecific synthesis of d(4)-5-epi-8,12-iso-iPF(3 alpha)-VI 55 and d(4)-8,12-iso-iPF(3 alpha)-VI 64, EPA-derived all-syn-isoprostanes (iPs), has been accomplished. Because of issues related to volatility and yield with some of the primary deuterated synthons an improved synthesis is presented. These two deuterated analogs were used to discover and quantify the presence of the corresponding endogenous isoprostanes in human urine. These assays may serve as a valuable index of oxidative stress in population with omega-3 fatty acid enriched diets containing eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) and may also be useful as an index of the severity of inflammatory diseases such as atherosclerosis and Alzheimer's disease.
