  • Title: The chemical structure of prostaglandin X (prostacyclin).
    Author: Whittaker N, Bunting S, Salmon J, Moncada S, Vane JR, Johnson RA, Morton DR, Kinner JH, Gorman RR, McGuire JC, Sun FF.
    Journal: Prostaglandins; 1976 Dec; 12(6):915-28. PubMed ID: 12538.
    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.
