| Abstract |
The preventive and therapeutic effects of 2-(10,11-dihydro-10-oxodibenzo [b,f]thiepin-2-yl)propionic acid (CN-100) on local and systemic changes of rats with adjuvant arthritis being used frequently as experimental model of rheumatoid arthritis were investigated in comparison with those of reference drugs, indometacin and pranoprofen. Preventively and therapeutically CN-100 showed potent inhibitory effects on adjuvant primary inflammation and secondary lesion. CN-100 also exerted an evident preventive effect on destruction of foot bone, improved the changes in organ weight, and stimulated weight gain. These effects were dose-dependent, and the effects at 5.0 mg/kg were almost the same as those of indometacin and pranoprofen at 1.25 and 2.5 mg/kg, respectively. The mode of action of CN-100 resembled that of reference compounds. Although CN-100 improved the change in albumin/globulin ratio, which was a parameter of systemic inflammatory reactions, the effect was more remarkable in therapeutic administration than in preventive one. This suggests that CN-100 is suitable for clinical application.
