Use of NS-398NS-398 is a non-steroidal an-inflammatory agent with analgesic and antipyretic effects, and selectively inhibits prostaglandin G/H synthase 2/cyclooxygenase 2 (COX-2) activity, with an IC50 of 3.8 μM, and has no effect on COX-1 at 100 μM. |

| In Vitro | NS-398 is a non-steroidal an-inflammatory agent, selectively inhibits prostaglandin G/H synthase/cyclooxygenase (COX-2) activity, with an IC50 of 3.8 μM, and has no effect on COX-1 at 100 μM[1]. NS-398 weakly inhibits PG endoperoxide synthase activity from sheep seminal vesicle microsomes (IC50, 11 μM)[2]. |
| In Vivo | NS-398 (0.5-10 mg/kg, p.o.) dose-dependently inhibits paw edema in rats, with an ED30 of 1.14 mg/kg, shows therapeutic effects on adjuvant arthritis (ED30, 4.69 mg/kg), exhibits dose-dependent analgesic activity (ED50, 1.65 mg/kg), and has antipyretic effect (ED50, 1.84 mg/kg) in rats. In mice, NS-398 suppresses writhing reactions induced by acetic acid with an ED50 of 8.2 mg/kg[2]. |
| Animal Admin | Mice[2] Briefly, male ddy mice weighing about 30 g are used. The writhing syndrome is induced by injecting 0.75% of acetic acid, intraperitoneally. Ten minutes later, the number of writhings are counted for the next 10 min. NS-398 is administered orally 30 min prior to the injection. The analgesic effect is expressed as % of inhibition, compared with the vehicle-treated control[2]. Rats[2] Briefly, male Lewis rats weighing about 160 g are used. Arthritis is induced by injecting 0.1 mL of 0.7% Mycobacterium tubercu-losis-liquid paraffin into the left hind paw. On day 15, the rats are grouped according to the degree of secondary lesions in the right hind paw. NS-398 is administered orally once daily from days 15 to 18. Foot volume is measured on day 19. Relative edema volume (REV) is calculated for each animal[2]. |
