15-keto Prostaglandin F1α from Cayman Chemical

15-keto PGF1α is the initial metabolite of PGF1α via 15-hydroxy PGDH. In mammals, oxidation of C-15 markedly attenuates receptor binding and activity. In fish, the 15-keto compounds serve as post-ovulatory pheromones and are more active than the parent prostaglandins.{1586}
