Common Name8-Isoprostaglandin E1
Description8-Isoprostaglandin E1, also known as iso-pge1 or ovinonic acid, belongs to the class of organic compounds known as prostaglandins and related compounds. These are unsaturated carboxylic acids consisting of a 20 carbon skeleton that also contains a five member ring, and are based upon the fatty acid arachidonic acid. Thus, 8-isoprostaglandin E1 is considered to be an eicosanoid lipid molecule. Thus, a total of 64 isomers can be generated for each of the D-, E-, and F{alpha}-ring isoprostanes. 8-Isoprostaglandin E1 is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. All eicosanoids function locally at the site of synthesis, through receptor-mediated G-protein linked signaling pathways. Nevertheless, isoprostanes are isomeric with prostaglandins and have been given the prefix D-, E-, and F{alpha}- to denote the prostane ring shared with PGD2, PGE2, and PGF2{alpha} respectively. Prostaglandins are eicosanoids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes) and leukotrienes from leukocytes, hence the derivation of their names. The isoprostanes embody a vast family of novel prostaglandin-like lipids that are produced by nonenzymatic peroxidation of arachidonic acid (AA) in response to free radicals and reactive oxygen species.
