Mechanism of Action

Targets/IC₅₀/Ki	COX
In vitro	Piroxicam induces activation of extracellular signal-regulated kinase (ERK) in neurones and phosphorylation of heavy molecular weight neurofilaments, cytoskeletal substrates of ERK in rat spinal cord cultures. This compound and NS-398 protect neurones against hypoxia/reperfusion in rat spinal cord cultures.
In vivo	Piroxicam at doses higher than 0.04%, strongly inhibits the development of GST-P-positive and neoplastic nodules as well as fibrosis, cirrhosis and formation of 8-hydroxydeoxyguanosine (8-OHdG) adducts in rats. This compound increases the expression of all three MHC antigens compared to either control or azoxymethane (AOM)-treated rats. It up-regulates colonic MHC antigen expression in the AOM model of colonic carcinogenesis. This chemical combined with Cisplatin has antitumor activity against oral malignant melanoma (OMM) and oral squamous cell carcinoma (SCC) in rats. It inhibits prostaglandin synthesis through cyclooxygenase blockade in dog, and does not have any direct cytotoxic effects in vitro. It also binds strongly to plasma proteins and could stop Ochratoxin A (OTA) -binding and transport into target organs, thereby preventing its nephrotoxicity in rats. This agent prevents the enzymuria induced by OTA and increases renal elimination of OTA in rats.
