Specialized pro-resolving lipid mediators are biosynthesized during the resolution phase of acute inflammation from n-3 polyunsaturated fatty acids. Recently, the isolation and identification of the four novel mediators denoted 13-series resolvins, namely, RvT1 (1), RvT2 (2), RvT3 (3) and RvT4 (4), were reported, which showed potent bioactions characteristic for specialized pro-resolving lipid mediators.

在急性炎症消退阶段,由n-3多不饱和脂肪酸生物合成专业的促分解脂质介体。最近,报道了分离和鉴定表示为13系列resolvins的四个新型介体,即RvT1(1),RvT2(2),RvT3(3)和RvT4(4),它们显示了专门的亲和力的有效生物作用特征。 -解析脂质介体。在此,根据LC / MS-MS代谢脂蛋白体学和13(R)-羟基-7Z,10Z,13R,14E,16Z,19Z二十碳五烯酸(13R-HDPA,5)的立体选择性合成结果,我们提供了直接的证据四个新的介体1-4都是从关键中间体5上生物合成的。合成13R-HDPA的UV和LC / MS-MS结果(5)与由体内感染性分泌液,内皮细胞和人重组COX-2酶获得的内源性和生物合成材料相匹配。使用在C-13原子上作为R构型的手性池起始材料,获得了立体化学纯的5。两个立体选择性Z-Wittig反应和两个Z选择性还原的内部炔烃在5中提供了几何上纯净
