Source	In most animal tissues prostanoids are synthesized enzymatically de novo upon physiological and pathological stimulations, and this is also the case of prostaglandin I2. Prostaglandin I2 is produced in blood vessels, lung and other tissues Moncada_S et al..
Chemical Synthesis	Johnson_RA et al.
Metabolism	Prostaaglandin I2 is produced by isomerization of 9,11-endoperoxide of prostaglandin H2 by the catalysis of prostaglandin I synthase Tanabe_T et al.. Prostaglandin I2 is unstable and decomposes readily to 6-keto-prostaglandin F2a. Its 2,3-dinor derivative is a major urinary metabolite Needleman_P et al..
Biological Activity	Prostaglandin I2 is a potent anti-aggregatory agent for platelets, relaxes blood vessels, and enhances vascular permeability Whittle_BJ et al.. It binds to a receptor with 7 transmembrne domains (IP) coupled to a Gs protein Negishi_M et al..
