13-epi-12-oxo Phytodienoic acid (13-epi-12-oxo PDA) is a lipoxygenase metabolite of α-linolenic acid in the leaves of green plants such as corn. ω-3 and ω-6 polyunsaturated fatty acids in plants are substrates for plant lipoxygenases. 12-oxo PDA is one of the best studied end metabolites of this enzymatic pathway. While the initial enzymatic product and major isomer of 12-oxo PDA contains side chains in the cis position, both being β to the ring, the upper side chain attached at C-13, can and frequently does, isomerize when 12-oxo PDA is extracted, isolated, or stored. 13-epi-12-oxo PDA is the product of this isomerization.

Fluindione is a hematologic drug.

AZD 4407 is a potent inhibitor of 5-lipoxygenase.

Texasin is a selective inhibitor of human leukocyte 5-lipoxygenase.

Isotachioside has15-lipoxygenase (15-LO) inhibitory activities.

1-Stearoyl-2-oleoyl-3-linoleoyl-rac-glycerol is a triacylglycerol consisting of stearic acid, oleic acid, and linoleic acid esterified at the sn-1, sn-2, and sn-3 positions, respectively. This compound is present in peanut and soybean oils as well as in ostrich and emu oils. Additionally, it serves as a substrate for soybean lipoxygenase in cell-free assays.

8(S)-HEPE is a monohydroxy fatty acid produced by lipoxygenase oxidation of EPA. It acts to promote hatching of barnacle eggs at 10 nM, although it is not clearly identified as the natural egg hatching factor.

9c(i472) is an inhibitor of 15-lipoxygenase-1 (15-LO-1; IC50 = 0.19 μM).1 It decreases LPS- and IFN-γ-induced NF- B activity in RAW-Blue cells when used at concentrations of 0.2, 1, and 5 μM. 9c(i472) reduces LPS- and IFN-γ-induced increases in Nos2 expression and lipid peroxidation in RAW 264.7 cells when used at a concentration of 5 μM.

Sigmoidin A has moderate antioxidant, antimicrobial and anti-inflammatory activity.
