Prostaglandin I2 (sodium salt)

Prostaglandin I2 (PGI2) is an unstable cyclooxygenase metabolite detected first in vascular endothelial cells. It elevates platelet cAMP and is a potent vasodilator and inhibitor of human platelet aggregation with an IC50 of 5 nM. PGI2 is stable in basic buffers (pH=8), but it is rapidly hydrolyzed to 6-keto PGF1alpha in neutral or acidic solutions. The half-life is short both in vivo and in vitro, ranging from 30 seconds to a few minutes. PGI2 is administered by continuous infusion in humans for the treatment of idiopathic pulmonary hypertension.Formal Name: 6,9alpha-epoxy-11alpha,15S-dihydroxy-prosta-5Z,13E-dien-1-oic acid, monosodium salt.
