9-Keto Fluprostenol, a potent analog of prostaglandin E2 (PGE2), features structural modifications aimed at enhancing its half-life and potency. It derives from Fluprostenol, a thoroughly researched, potent analog of PGF2α, primarily interacting with the FP receptor. The creation of 9-Keto Fluprostenol through the oxidation at C-9 of Fluprostenol suggests a high affinity for EP receptors, potentially functioning as a PGE2 agonist.
