Oxaprozin is aCOX inhibitor with IC50s of 2.2 μM and 36 μM for human platelet COX-1 and IL-1-stimulated human synovial cell COX-2, it's a NSAID used to relieve the inflammation, swelling, stiffness, and joint pain associated with osteoarthritis and rheumatoid arthritis.
Oxaprozin is an inhibitor of both COX-1 and COX-2 with IC50s of 2.2 μM and 36 μM for human platelet COX-1 and IL-1-stimulated human synovial cell COX-2, respectively. Oxaprozin also inhibits the activation of NF-κB. Oxaprozin reversed in a dose-dependent manner immune complex-induced survival of monocytes, without affecting the apoptosis of resting cells. Other NSAIDs (Non-steroidal anti-inflammatory drugs) are ineffective. Oxaprozin-mediated inhibition of the Akt/IKK/NF-kappaB pathway contributes to its anti-inflammatory properties[3]. Among different NSAIDs, only oxaprozin dose-dependently increased apoptosis of CD40L-treated monocytes. Oxaprozin pro-apoptotic activity was associated with the inhibition of CD40L-triggered Akt and NF-kappaB phosphorylation and the activation of caspase 3[4].
