Grapiprant is a selective EP4 receptor antagonist whose physiological ligand is prostaglandin E2 (PGE2)

Grapiprant, also known as CJ-023,423, RQ-00000007 and AAT-007, is a novel, potent and selective prostaglandin EP4 receptor antagonist with antihyperalgesic properties. In vitro, CJ-023,423 inhibits [(3)H]PGE(2) binding to both human and rat EP(4) receptors with K(i) of 13 +/- 4 and 20 +/- 1 nM, respectively. CJ-023,423 is highly selective for the human EP(4) receptor over other human prostanoid receptor subtypes. It also inhibits PGE(2)-evoked elevation in intracellular cAMP at the human and rat EP(4) receptors with pA(2) of 8.3 +/- 0.03 and 8.2 +/- 0.2 nM, respectively. In vivo, oral administration of CJ-023,423 significantly reduces thermal hyperalgesia induced by intraplantar injection of PGE(2) (ED(50) = 12.8 mg/kg).
