8-iso-15-keto Prostaglandin F (8-iso-15-keto PGF) is a metabolite of the isoprostane 8-iso PGF in rabbits, monkeys, and humans. 8-isoprostane (8-iso PGF) is a prostaglandin-like product of non-specific lipid peroxidation. In both humans and monkeys, exogenously infused 8-iso PGF 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 PGF is infused into rabbits. Early in the infusion (within 1-2 minutes) 8-iso -15-keto PGF was a major component of the metabolite profile, which was comprised mostly of unmetabolized 8-iso PGF 8-iso -15-keto PGF is a vasoconstrictor when tested on the rat isolated thoracic aorta, acting via the TP (thromboxane) receptor.
8-iso-15-keto Prostaglandin F2α is a partial agonist for Thromboxane receptor (TP), which exhibits a vasoconstrictor efficacy with a pD2 of 5.8. 8-iso-15-keto Prostaglandin F2α mediates a weak relaxation of rats aorta rings at high concentration.
