Sample Use Guides

In the indometacin-induced gastric mucosal injury, rats were treated with indometacin and then nabumetone or 6MNA (6-Methoxy-2-Naphthylacetic acid) was orally administered. Nabumetone prevented gastric damage accompanied by the reduction of neutrophil infiltration into gastric mucosa, but such an effect was not observed with 6MNA
Route of Administration: Oral
In Vitro Use Guide
Curator's Comment:: 6MNA (6-Methoxy-2-Naphthylacetic acid) had variable effects on cyclooxygenase activity, depending on the concentration and was less potent and less effective than indomethacin. Sulphasalazine inhibited 15-PGDH in a concentration-dependent manner whereas 6MNA inhibited it only at high concentrations. Basal 5-lipoxy-genase (5-L) activity was attenuated by phenidone and unaltered by 6MNA but increased by nabumetone at the highest concentration. In the presence of arachidonic acid, to raise 5-LO activity, nabumetone, 6MNA, BW755C and phenidone apparently inhibited this activity. However, it was possible that both nabumetone and 6MNA inhibited a prostanoid-mediated stimulatory effect on 5-LO rather than effecting enzyme inhibition per se.
