13,14-dihydro-15-keto Prostaglandin E2 (13,14-dihydro-15-keto PGE2) serves as the predominant metabolite of PGE2 in plasma, created through a 15-keto PGE2 intermediate by the action of 15-oxo-PG Δ13 reductase. Unlike its precursor PGE2, this compound exhibits poor binding affinity towards EP2 and EP4 PGE2 receptors (Ki values of 12 and 57 µM, respectively) in CHO cells and fails to stimulate adenylate cyclase activity therein (EC50s >18 and >38 µM, respectively). Concentrations of 13,14-dihydro-15-keto PGE2 are notably higher in the plasma of pregnant women during their third trimester and at labor and delivery stages, whereas its levels are found to be reduced in the tumor tissues of patients with non-small cell lung cancer (NSCLC) compared to adjacent healthy tissue.

Enzymatically-derived prostaglandin E2 (PGE2) is an optically pure compound whereas PGE2 derived from the free radical-catalyzed peroxidation of arachidonate is a racemic mixture. Ent-PGE2 is the opposite enantiomer of PGE2. Significant amounts of racemic PGE2 (rac-PGE2) are generated in vitro and in vivo in settings of oxidative stress via the isoprostane pathway. A proposed mechanism for the formation of rac-PGE2 involves the base catalyzed equilibration from 15-E2t-isoprostane (8-iso-PGE2), generated from the 15-H2t-isoprostane endoperoxide.

19(R)-Hydroxylated prostaglandins (PGs) are present at µg/ml concentrations in the semen of some mammalian species, notably primates, with the majority being from the PGE series and featuring a 15(S),19(R) hydroxyl stereochemistry. These compounds are also observed in marsupials' seminal plasma, where F-type 1 and 2-series compounds are predominant. The 15(R)-hydroxy epimer represents the inverse or unnatural isomer at C-15 for these 19-hydroxylated PGs. Although the biological function of 19(R)-hydroxylated PGs remains unclear, 19(R)-hydroxylation in the F-series leads to a notable reduction in receptor-mediated biological activity in certain assays.

8-iso-15(R)-Prostaglandin F2α (8-iso-15(R) PGF2α) is a chemically distinct member within a broad group of prostaglandin-like eicosanoids, produced through the free radical peroxidation of arachidonic acid contained in membrane phospholipids. It represents the C-15 epimer of 8-isoPGF2α, distinguished as the sole isoprostane isomer extensively examined across numerous biological systems.
