急性炎症反应的消退取决于吞噬细胞主动清除凋亡细胞和病原体。专门化的前分解介质(SPM)的生物合成通过其在天然免疫细胞中的作用在消解炎症中起着关键作用。E4(RvE4:5S,15S-二羟基二十碳五烯酸)是由二十碳五烯酸(EPA)生物合成的E系列分解蛋白中的一个新成员,最近在生理缺氧中被发现。这种新的解决素被称为RvE4,因为它有能力增加巨噬细胞对凋亡细胞的吞噬作用。在此,我们报道了RvE4的全有机合成,确认了其独特的结构、完整的立体化学结构和功能。这种合成的RvE4符合生物RvE4材料的物理性质,即紫外线(UV)吸光度、层析行为、串联质谱仪(MS2)裂解以及生物活性。我们证实了RvE4对人M2巨噬细胞吞噬人凋亡的中性粒细胞和衰老的红细胞的有效反应。总之,这些结果为将RvE4的完整立体化学指定为5S,15S-dihydroxy-6E,8Z,11Z,13E,17Z-eicosapentaenoic酸及其在人类吞噬细胞反应中的生物作用提供了直接证据。
The resolution of the acute inflammatory response is governed by phagocytes actively clearing apoptotic cells and pathogens. Biosynthesis of the specialized pro-resolving mediators (SPMs) is pivotal in the resolution of inflammation via their roles in innate immune cells. Resolvin E4 (RvE4: 5S,15S-dihydroxy-eicosapentaenoic acid) is a newly uncovered member of the E-series resolvins biosynthesized from eicosapentaenoic acid (EPA) recently elucidated in physiologic hypoxia. This new resolvin was termed RvE4 given its ability to increase efferocytosis of apoptotic cells by macrophages. Herein, we report on the total organic synthesis of RvE4 confirming its unique structure, complete stereochemistry assignment and function. This synthetic RvE4 matched the physical properties of biogenic RvE4 material, i.e. ultra-violet (UV) absorbance, chromatographic behavior, and tandem mass spectrometry (MS2) fragmentation, as well as bioactivity. We confirmed RvE4 potent responses with human M2 macrophage efferocytosis of human apoptotic neutrophils and senescent red blood cells. Together, these results provide direct evidence for the assignment of the complete stereochemistry of RvE4 as 5S,15S-dihydroxy-6E,8Z,11Z,13E,17Z-eicosapentaenoic acid and its bioactions in human phagocyte response.
