prostaglandin e 2

Prostaglandin E2 (PGE2) is a naturally occurring hormone involved in various physiological processes, such as smooth muscle contraction and relaxation, vasodilation and constriction, blood pressure regulation, and inflammatory regulation.

5-trans-Prostaglandin E2 accelerates fibrinolysis by enhancing plasminogen activation mediated by tissue-type plasminogen activator. It also inhibits platelet aggregation in human PRP.

8-iso PGE2 is one of several isoprostanes produced from arachidonic acid during lipid peroxidation. It is a potent renal vasoconstrictor in the rat. 8-iso PGE2 inhibits U-46619 or I-BOP-induced platelet aggregation with IC50 values of 0.5 and 5 μM, respectively. When infused into the renal artery of the rat at a concentration of 4 μg/kg/min, 8-iso PGE2 decreases the GFR and renal plasma flow by 80% without affecting blood pressure.
