An mPGES-1 inhibitor (IC50 = 0.2 µM); selective for mPGES-1 over COX-1, COX-2, 5-LO, and sEH in cell-free assays at 10 µM; inhibits IL-1β-induced production of PGE2 in A549 cells and LPS-induced IL-6 and PGE2 production in J774A.1 macrophages at 10 and 1 µM, respectively; inhibits the formation of 5-LO products, including LTB4 and 5-H(p)ETE, induced by A23187 alone or with arachidonic acid and A23187 (IC50s = 4.9 and 5.2 µM, respectively); prevents leukocyte infiltration into the peritoneal fluid in a mouse model of zymosan-induced peritonitis at 10 mg/kg
