| Abstract: | Eight new ω-(indol-3-yl)alkane carboxamides were synthesized and studied for their antiinflammatory activities against carrageenin induced paw oedema in albino rats. Six compounds exhibited various degrees of antiinflammatory activity, two compounds showed no activity. The most potent compound of the present series, 1-(indol-3-yl)-N-{4-[1-(4-methylphenyl)piperazinyl]phenyl}acetamide (7) as well as phenylbutazone showed dose dependent inhibition of rat paw oedema. The ulcerogenic activities of compound 7 and phenylbutazone were also dose dependent. However, 7 showed a much lower ulcerogenic activity. In view of its potent antiinflammatory activity, minimal ulcerogenic liability and low acute toxicity compound 7 appears promising. |
