Imrecoxib (BAP-909) is a novel and selective cyclooxygenase 2 (COX-2) inhibitor with an IC50 value of 18 nM, it also inhibits COX1- activity with an IC50 value of 115 nM. Imrecoxib (BAP-909) has anti-inflammatory effect[1]. Human COX-1|115 nM (IC50)|Human COX-2|18 nM (IC50)

Imrecoxib (BAP-909) (0.1-10 μM; 24 hours) decreases COX-2 mRNA level induced by PMA+LPS at a dose dependent manner in U937 cells[1]. RT-PCR[1] Cell Line: U937 cells

Imrecoxib (BAP-909) (gastrointestinal administration; 5-20 mg/kg; 1 hour before carrageenan injection) inhibits carrageenan-induced acute inflammation, and the inhibitory effect is maximal at 4 hours[1].Imrecoxib (BAP-909) (gastrointestinal administration; 5-20 mg/kg; started on day 7; 26 days) diminishes the secondary paw swelling and inhibits heat-inactivated BCG induced-inflammtory polyarthritis[1]. Animal Model: Rat carrageenan-induced edema model[1]
