prostaglandin e2

Prostaglandin E2 (PGE2) is a natural hormone-like substance involved in various physiological functions, including the contraction and relaxation of smooth muscles, dilation and constriction of blood vessels, regulation of blood pressure, and modulation of inflammation. It can be used to induce neuropathic pain models.

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.
