Nine compounds were selected for in vivo testing and evaluated for their potency to decrease carrageenin-induced edema in rats. The compounds were applied i.p. at doses 20 mg/kg and 40 mg/kg and p.o. at doses 10 mg/kg and 40 mg/kg. Six compounds showed more than 70% protection of the edema. Indomethacin (2 mg/kg i.p.), used as a reference drug, possessed 54% anti-inflammatory activity under similar experimental conditions.
