[Met5]-Enkephalin, amide, is an agonist for δ opioid receptors and putative ζ (zeta) opioid receptors. Met-enkephalin circulates in several forms, some potentially derived from proteins other than proenkephalin A, with plasma levels including both free and bound forms.

Prostaglandin F1α (PGF1α) is the putative metabolite of dihomo-γ-linolenic acid (DGLA) via the cyclooxygenase (COX) pathway. Both PGF1α and PGF2α have been shown to act as priming pheromones for male Atlantic salmon with a threshold concentration of 10-11 M. [1] PGF1α binds to the ovine corpus luteum FP receptor at only 8% of the relative potency of PGF2α. [2] It is only half as active as PGF2α in inducing human respiratory smooth muscle contractions in vitro. [3]

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.

Tenuazonic acid is a putative nonhost-selective mycotoxin isolated from Alternaria alternate. Tenuazonic acid blocks electron transport beyond primary quinone acceptor (QA) by interacting with D1 protein and it is a broad-spectrum and effective photosyste

Oxiperomide is a dopamine D2 and muscarinic M1 receptor ligand. It also has putative antipsychotic and pro-cognitive potential.

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-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] .
