| Parecoxib | Parecoxib (SC 69124) is a highly selective and orally active COX-2 inhibitor, the proagent of Valdecoxib (HY-15762). Parecoxib Sodium is a nonsteroidal anti-inflammatory agent (NSAID) and inhibits prostaglandin (PG) synthesis. Parecoxib can be used for the relief of acute postoperative pain and symptoms of chronic inflammatory conditions such as osteoarthritis and rheumatoid arthritis in vivo. Uses: Scientific research. Group: Signaling pathways. Alternative Names: SC 69124. CAS No. 198470-84-7. Pack Sizes: 10 mM * 1 mL; 25 mg; 50 mg; 100 mg. Product ID: HY-17474. |  |

| Parecoxib Impurity 1 | An impurity of Parecoxib. The prodrug Parecoxib as well as its active metabolite val have a specific affinity to the cannabinoid (CB) receptor measured in CB1-expressing HEK 293 cells and rat brain tissue. Adult male Sprague-Dawley rats were administered parecoxib (10 or 30 mg kg(-1), IP) or isotonic saline twice a day starting 24 h after middle cerebral artery occlusion (MCAO) for three consecutive days. The selective COX-2 inhibitor parecoxib was delivered 20 min before or 20 min after the incision by intraperitoneal injection.
