Biological Activity
Potent EP4 receptor antagonist (IC50 = 59 nM). Suppresses EP4-mediated Th1 differentiation, Th17 cell expansion, and IL-23 secretion by activated dendritic cells. Inhibits Th1 and Th17 cytokine production, suppresses collagen- and GPI-induced arthritis in mice. Attenuates CFA-induced inflammatory pain in rats. Analgesic. Orally bioavailable.
