8 iso prostaglandin f2β

8-iso Prostaglandin F2β can be used in related research in the field of life sciences. Its product number is T37165 and CAS number is 177020-26-7.

8-iso Prostaglandin F2α ethanolamide (iPF2α-III ethanolamide; 8-Isoprostane ethanolamide; 8-iso PGF2α ethanolamide) is a derivative of isoprostane ethanolamide produced through the non-enzymatic free radical oxidation of arachidonoyl ethanolamide (AEA). It is commonly used as a biomarker for oxidative stress, helping to distinguish non-enzymatic breakdown products from enzyme-mediated prostamides generated via pathways such as COX-2.

ent-8-iso Prostaglandin F2α is a potent vasoconstrictor of porcine retinal and cerebral microvessels with EC50 values of 30.6 and 53.5 nM, respectively.

8-Isoprostaglandin F2α is a natural product for research related to life sciences. The catalog number is T37164 and the CAS number is 27415-26-5.

8-isoProstaglandin F2α (8-isoPGF2α; 8-isoprostane) is a byproduct of non-specific lipid peroxidation, resembling prostaglandin in structure. In humans and rats, its metabolite, 12,3-dinor-8-isoPGF2α, is formed following exogenous administration of 8-isoPGF2α, which is converted to 2,3-dinor-8-isoPGF1α and 2,3-dinor-8-isoPGF2α. Additionally, rat hepatocytes can further break down 8-isoPGF2α into a β-oxidation product, 2,3,4,5-tetranor-8-isoPGF2α. The metabolite, 2,3-dinor-8-isoPGF2α, is normally found in human urine at concentrations of 200-300 pg/ml. Its levels rise in conditions associated with oxidative stress, such as smoking, demonstrating a correlation with the concentration of its precursor, 8-isoPGF2α.

8-iso Prostaglandin F2β (8-iso PGF2β) is an isomer of PGF2α of non-enzymatic origin. It is one of 64 possible isomers of PGF2α which can be produced by free radical peroxidation of arachidonic acid. 8-iso PGF2β exhibits very weak contraction of human umbilical vein artery and does not promote aggregation of human whole blood. However, 8-iso PGF2β moderately contracts both the canine and porcine pulmonary vein, although the effect is much weaker than that exhibited by other isoprostanes such as 8-iso PGE1, 8-iso PGE2, or 8-iso PGF2α. 8-iso-15-keto PGF2β is a potential metabolite of 8-iso PGF2β via the 15-hydroxy PG dehydrogenase pathway. There are no published reports on the formation or biological activity of 8-iso-15-keto PGF2β.

8-Iso-17-phenyl trinor prostaglandin F2β is an isomer of Bimatoprost. Bimatoprost, a prostaglandin analog, works by reducing intraocular pressure through the regulation of uveoscleral and trabecular outflow.

Isoprostanes are produced by the non-enzymatic, free radical peroxidation of phospholipid-esterified arachidonic acid. They have been used as biomarkers of oxidative stress, but they also have been found to have potent biological activity. ent-8-iso-15(S)-Prostaglandin F2α (ent-8-iso-15(S)-PGF2α) is a potent vasoconstrictor of porcine retinal and brain microvessels with EC50 values of 15 and 24 nM, respectively. This isoprostane is about ten-fold more potent than 8-iso-PGF2α in a whole blood platelet aggregation inhibition assay.

8-iso-13,14-dihydro-15-keto Prostaglandin F2α (8-iso-13,14-dihydro-15-keto PGF2α) is a metabolite of the isoprostane, 8-isoprostane (8-iso PGF2α), in rabbits, monkeys and humans. 8-iso PGF2α is a PG-like product of non-specific lipid peroxidation. In both humans and monkeys, exogenously infused 8-isoprostane 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-isoprostane is infused into rabbits. Early in the infusion (within 10 minutes) 8-iso-13,14-dihydro-15-keto PGF2α was a significant component of the metabolite profile, which was comprised mostly of dinor 8-isoprostane metabolites. 8-iso-13,14-dihydro-15-keto PGF2α weakly inhibits the U-46619 or collagen-induced aggregation of human platelets, although a number of the E-series isoprostanes are much more potent in this assay.

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-iso PGF2α is a prostaglandin-like product of non-specific lipid peroxidation. In humans and monkeys, exogenously infused 8-iso PGF2α is converted to metabolites with 2 or 4 carbon atoms removed from the top side chain by β-oxidation, with a similar pattern observed in tritiated 8-iso PGF2α-infused rabbits. Early in the infusion (within 1-2 minutes), 8-iso-15-keto PGF2α is a major component of the metabolite profile, primarily comprising 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.

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.
