Prostaglandin E2 (PGE2) activates four E prostanoid (EP) receptors, EP1-4. EP4 is a Gs protein-coupled receptor that, by elevating the second messenger cAMP, plays important roles in bone formation and resorption,1 cancer,2 and atherosclerosis.3 CAY10580 is an 8-aza-9-oxo-15-hydroxy saturated analog of PGE2. It selectively binds the EP4 receptor (Ki = 35 nM) relative to the EP1, EP2, and EP3 receptors (Ki = 3,000, 2,000, and >3,000 nM, respectively).4 CAY10580 stimulates cAMP formation in excised mouse ovaries.5
