(±)12-HEPE is produced by non-enzymatic oxidation of EPA. It contains equal amounts of 12(S)-HEPE and 12(R)-HEPE. The biological activity of (±)12-HEPE is likely mediated by one of the individual isomers, most commonly the 12(S) isomer in mammalian systems. 12-HEPE inhibits platelet aggregation with the same potency as 12-HETE, exhibiting IC50 values of 24 and 25 µM, respectively. [1] These compounds are also equipotent as inhibitors of U46619-induced contraction of rat aorta (IC50s = 8.6-8.8 µM).[2]

The early stage of atherosclerosis is characterized by the aggregation of foam cells, so called a fatty streak, in the inner arterial wall. CAY10487 inhibits formation of fatty streak lesions of the thoracic aorta in high cholesterol-fed rabbits without affecting plasma lipid profiles or significantly inhibiting ACAT-1 or ACAT-2 activity. The percent area occupied by the atherosclerotic lesion in rabbits supplemented with 0.05% CAY10487 in the diet was 16.1% compared to 53.5% in control rabbits. CAY10487 also exhibits antioxidant activity, inhibiting copper-mediated oxidation of low-density lipoprotein by about 75% at a concentration of 2 μM.

8-iso-15-keto Prostaglandin F2α (8-iso-15-keto PGF2α) is a metabolite of the isoprostane 8-iso PGF2α in rabbits, monkeys, and humans. 8-isoprostane (8-iso PGF2α) is a prostaglandin-like product of non-specific lipid peroxidation. In both humans and monkeys, exogenously infused 8-iso PGF2α is converted primarily to metabolites having 2 or 4 carbon atoms removed from the top side chain by β-oxidation. A similar pattern is observed when tritiated 8-iso PGF2α is infused into rabbits. Early in the infusion (within 1-2 minutes) 8-iso -15-keto PGF2α was a major component of the metabolite profile, which was comprised mostly of unmetabolized 8-iso PGF2α. 8-iso -15-keto PGF2α is a vasoconstrictor when tested on the rat isolated thoracic aorta, acting via the TP (thromboxane) receptor.

Prostaglandin A1 (PGA1) was first isolated as a dehydration product of the PGE1 compounds found in human semen. 15-keto PGA1 is a metabolite of PGA1, produced by 15-hydroxy PG dehydrogenase. It can be produced from PGA1 in pig lung, trachea, aorta, and pulmonary artery tissue preparations. 15-keto PGA1, given at a concentration of 6 μM, causes vasoconstriction of rabbit lung that is comparable to that induced by angiotensin II.

Adrenomedullin (13-52) is a truncated form of adrenomedullin (1-52) . It induces nitric oxide-dependent relaxation of and inhibits release of angiotensin II and endothelin-1 from isolated rat aorta. In vivo, adrenomedullin (13-52) decreases mean arterial pressure (MAP) in spontaneously and renal hypertensive rats in a dose-dependent manner. Adrenomedullin (13-52) (10-3,000 ng per animal) reverses increases in lobar arterial pressure induced by U-46619 in a dose-dependent manner in cats but has no effect on basal lobar arterial pressure or systemic arterial pressure. It also potentiates inflammatory edema and neutrophil accumulation in rats.
