Anti-inflammatory mechanism of 2-(2-fluoro-4-biphenylyl) propionic acid (Flurbiprofen, FP-70) was studied by various analysis in comparison with other drugs. It was found in the test of rat edema induced by various phlogists that carrageenin and yeast-induced edemas were markedly inhibited by FP-70, whereas dextran, formalin, serotonin and bradykinin-induced edemas were scarcely inhibited by FP-70. The action of FP-70 was similar to that of soy bean trypsin inhibitor. However, FP-70 showed no effects on kinin synthetase and kininase. FP-70 showed a marked inhibition on prostaglandin synthesis. The inhibitory effect of FP-70 was 10.1, 96.5 and 2280.6 times as large as indomethacin, ibuprofen and acetylsalicylic acid, respectively. FP-70 did not inhibit the permeability of dye induced by prostaglandin E2 in the rat skin. FP-70 inhibited the acid phosphatase and beta-glucuronidase activities of isolated lysosome of rat liver and also suppressed the release of acid phosphatase from the lysosome. These effects were similar to those of indomethacin. On the other hand, FP-70 suppressed markedly the heat-induced hemolysis of dog erythrocytes. The effect was similar to that of indomethacin and was 10 times stronger than those of ibuprofen, ibufenac and phenylbutazone. Activation of rat liver mitochondrial ATPase by FP-70 at a concentration of 10 muM was 74.7%, while indomethacin showed 37.8% activation at the same concentration. FP-70 as well as ibuprofen and phenylbutazone uncoupled the oxidative phosphorylation in rat liver mitochondria. From the above and previously reported results, it is suggested that the potent anti-inflammatory action of FP-70 is the result of the following effects; inhibition on the protein and leucocyte migration, inhibition on the prostaglandin synthesis, stabilization of the cell membrane and activation of ATPase.
