Abstract
AHR-10037 is an anti-inflammatory compound possessing analgesic and antipyretic properties and a high therapeutic index. AHR-10037 was comparable to indomethacin in suppressing acute (Evans blue-carrageenan pleural effusion) and chronic (adjuvant-induced arthritis) inflammation. There was a delayed onset of antipyresis (yeast-induced hyperthermia in rats), analgesia (acetylcholine-induced abdominal constriction in mice) and inhibition of caster oil-induced diarrhea in rats. Antipyresis occurred 3 hours after administration of AHR-10037, 4 mg/kg, PO, vs 1 hour after administration of acetylsalicylic acid, 100 mg/kg, PO; maximum analgesic activity (ED50-4.1 mg/kg) occurred at 4 hours. AHR-10037 was inferior to indomethacin in suppressing castor oil-induced diarrhea in rats. The therapeutic index of AHR-10037 (relating acute anti-inflammatory potency to gastric toxicity potency relative to indomethacin) ranged from 56–91. The pharmacological profile suggests that AHR-10037 is a prodrug convertedin vivo to a cyclooxygenase inhibitor.
