(±)14hdha

(±)14-HDHA是一种羟基二十二碳六烯酸，是DHA在细胞内通过酶促或非酶促反应生成的氧化代谢物，是15-PGDH的特异性底物之一并且可以被进一步氧化为具有抗炎性的14-oxoDHA，在原代肺泡巨噬细胞中，14-HDoHE 本身也能显著抑制 LPS 诱导的 IL-6 mRNA 表达，可能与哮喘等炎症性疾病有关。

Docosahexaenoic acid is a nutritionally-derived ω-3 fatty acid that is abundant in the brain and the retina and is thought to be important in early development and for therapeutic approaches to inflammatory disorders and cancer. 14(S)-HDHA is an oxygenation product of DHA that serves as a precursor to maresin 1 , an anti-inflammatory, pro-resolving mediator that prevents polymorphonuclear neutrophil (PMN) infiltration and stimulates macrophage phagocytosis. At doses as low as 0.2 ng/mouse 14(S)-HDHA administration resulted in reduced infiltration of PMNs into sites of inflammation.
