The chemical structure of prostaglandin X (prostacyclin)

N Whittaker et al. Prostaglandins. 1976 Dec.

Abstract

The chemical structure of prostaglandin X, the anti-aggregatory substance derived from prostaglandin endoperoxides, is 9-deoxy-6, 6alpha-epoxy-delta5-PGF1alpha. The stable compound formed when prostaglandin X undergoes a chemical transformation in biological systems in 6-keto-PGF1alpha. Prostaglandin X is stabilized in aqueous preparations by raising the pH to 8.5 or higher. The trivial name prostacyclin is proposed for 9-deoxy-6, 9alpha-epoxy-delta5-PGF1alpha.
