(±)17-HDHA is an autoxidation product of docosahexaenoic acid in vitro. It is also produced from incubations of DHA in rat liver, brain, and intestinal microsomes. 17(S)-HDHA could be produced by enzymatic oxidation of DHA using soybean lipoxygenase (LO) and is the putative product of mammalian 15-LOs. 17(S)-HDHA was shown to be an inhibitor of U-46619 -induced rabbit and rat aortic smooth muscle contraction with IC50 values of 4.9 and 7.2 μM, respectively. (±)17-HDHA is a potential marker of oxidative stress in brain and retina where DHA is an abundant polyunsaturated fatty acid.

Ganglioside GT1b is a trisialoganglioside that is characterized by having two sialic residues linked to the inner galactose unit. It binds to the neurotoxins botulinum toxin serotype A (BTxA), BTxA heavy chain, and tetanus toxin with IC50 values of 11, 0.74, and 7.2 μM, respectively.[1] Ganglioside GT1b-containing liposomes bind to the major coat protein VP1 from Merkel cell polyomavirus (MCPyV), which has been identified in Merkel cell carcinomas, identifying ganglioside GT1b as a putative MCPyV receptor. [2] Ganglioside GT1b decreases production of IL-6, IL-10, IgG, IgM, and IgA in human peripheral blood mononuclear cells (PBMCs) by 31.4, 30.5, 60, 59.5, and 58%, respectively, when used at a concentration of 10 μM [3] . Ganglioside GT1b mixture contains ganglioside GT1b molecular species with C18:1 and C20:1 sphingoid backbones.

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.

Biosynthesis of LTA3 occurs from 5,8,11-eicosatrienoic acid via the 5-LO pathway and it is the putative intermediate in the biosynthesis of 3-series leukotrienes. LTA3 as a free acid is highly unstable. The methyl ester is stable and can be readily hydrolyzed to the free acid as needed.

20-hydroxy Prostaglandin E2 (20-hydroxy PGE2) is a product of cytochrome P450 metabolism of PGE2 . ω-Oxidation at C-20 followed by β-oxidation and the loss of up to four carbons from the lower side chain is a prominent metabolic pathway for PGE2. 20-hydroxy PGE2 is the putative first intermediate in this chain of chemical transformations.
