8-iso Prostaglandin F2alpha-d4

8-iso PGF2alpha-d4 is intended for use as an internal standard for the quantification of 8-iso PGF2alpha by GC- or LC-mass spectrometry. 8-iso Prostaglandin F2alpha (8-iso PGF2alpha) is an isoprostane produced by the non-enzymatic peroxidation of arachidonic acid in membrane phospholipids. It circulates in human plasma in two distinct forms - esterified in LDL phospholipids and as the free acid. The ratio of these two forms is approximately 2:1, with a total plasma 8-iso PGF2alpha level of about 150 pg/ml in normal volunteers. In normal human urine, 8-iso PGF2alpha levels are about 180-200 pg/mg of creatinine. 8-iso PGF2alpha is a weak TP receptor agonist in vascular smooth muscle. Conversely, 8-iso PGF2alpha inhibits platelet aggregation induced by U-46619 (10-6 M) and I-BOP (3 x 10-7 M) with IC50 values of 1.6 x 10-6 M and 1.8 x 10-6 M, respectively.Formal Name: 9alpha,11alpha,15S-trihydroxy-(8beta)-prosta-5Z,13E-dien-1-oic-3,3,4,4-d4 acid.
