4-oxo Docosahexaenoic acid (4-oxo DHA) is a putative metabolite of DHA with antiproliferative and PPARγ agonist activity. It inhibits the growth of several triple negative breast cancer cell lines (MCF-10F, trMCF, bsMCF, MDA-MB-231, and BT549) at 50-100 μM, however it increased proliferation of MCF-7 cells. 4-oxo DHA binds covalently to PPARγ and activates gene transcription in luciferase reporter assays and in dendritic cells with EC50 values of approximately 8-16 μM.

17-oxo-4(Z),7(Z),10(Z),13(Z),15(E),19(Z)-Docosahexaenoic acid is a metabolite of lipoxygenase-mediated oxidation of DHA that is produced endogenously by aspirin-enhanced COX-2 activity. It has been shown to activate Nrf2-dependent antioxidant gene expression, to act as a PPARγ agonist (EC50 = ~200 nM), and to inhibit pro-inflammatory cytokine and nitric oxide production at biological concentration ranges (5-25 μM).

Docosahexaenoic acid alkyne, an ω-alkyne derivative of docosahexaenoic acid, enables Cu(I)-catalyzed cycloaddition with azide-containing molecules for efficient click chemistry applications.

Additionally, this compound permits the monitoring of fatty acid metabolism in cells through click chemistry linkage to fluorophores.

Resolvins are a family of potent lipid mediators derived from both eicosapentaenoic acid and docosahexaenoic acid.[1] In addition to being anti-inflammatory, resolvins promote the resolution of the inflammatory response back to a non-inflamed state.[2] Resolvin D1 is produced physiologically from the sequential oxygenation of DHA by 15- and 5-lipoxygenase.[1] 17(R)-RvD1 is an aspirin-triggered epimer of RvD1 that reduces human polymorphonuclear leukocyte (PMN) transendothelial migration, the earliest event in acute inflammation, with equipotency to RvD1 (EC50 = ~30 nM).[3] 17(R)-RvD1 exhibits a dose-dependent reduction in leukocyte infiltration in a mouse model of peritonitis with maximal inhibition of ~35% at a 100 ng dose.[3] In contrast to RvD1, the aspirin-triggered form resists rapid inactivation by eicosanoid oxidoreductases. Analytical and biological comparisons of synthetic 17(R)-RvD1 with endogenously derived 17(R)-RvD1 have confirmed its identity as matching the natural product.[4]
