AH22921 is a selective antagonist of the EP4 prostaglandin receptor, inhibiting the activation of adenylate cyclase by prostaglandins in CHO cells. This compound is characterized by its ability to shift the PGE2 concentration-response curve to the right, demonstrating its non-competitive antagonistic effect specifically on EP4 receptors. Notably, AH22921 does not influence the PGE2 concentration-response curve in NPE cells that express EP2 receptors, making it a valuable tool for studying EP4 receptor signaling in varied biological contexts.
