Notes: 15(R)-Prostaglandin I2 (15(R)-PGI2) is an isomer of the natural 15(S) prostanoid, PGI2 (Item No. 18220). PGI2 is an unstable cyclooxygenase metabolite detected first in vascular endothelial cells.{502,443,933} It elevates platelet cAMP and is a potent vasodilator and inhibitor of human platelet aggregation with an IC50 value of 5 nM.{4375} While the physiological properties of 15(R)-PGI2 are not well known, 15(R) isomers of PGs typically have reduced receptor agonist activity compared to their 15(S) forms.
