11-keto Fluprostenol

11-Keto Fluprostenol, a potent analog of prostaglandin F2? (PGF2?), primarily interacts with the FP receptor. It is a structurally modified derivative of prostaglandin D2 (PGD2) designed to enhance its potency and extend its half-life. The compound is produced by oxidizing fluprostenol at the C-11 position, which results in 11-keto fluprostenol. This modification allows 11-keto Fluprostenol to exhibit moderate affinity for the CRTH2/DP2 receptor, though it shows negligible activity at the DP1 receptor, distinguishing its action from that of PGD2.
