The synthesis and antiinflammatory activity of 5-substituted 2-arylbenzoxazoles are described. Initial screening on carrageenin-induced rat paw edema showed that alpha-methylacetic substitution in the 5 position was preferable to substitutions with the equivalent esters, amides, alcohols, amines or tetrazoles. Halogen substitution in the aryl ring led to the most active compounds which were 2-(4-c
描述了5-取代的2-芳基苯并恶唑的合成和抗炎活性。最初对角叉菜胶诱导的大鼠爪水肿的筛查表明,在5位上的α-甲基乙酸取代比同等的酯,酰胺,醇,胺或四唑取代更好。芳基环中的卤素取代导致活性最高的化合物为2-(4-氯苯基)-α-甲基-5-苯并恶唑乙酸(14)和2-(4-氟苯基)-α-甲基-5-苯并恶唑乙酸(29)。根据单次口服5小时后大鼠爪水肿的ED30值评估,这些化合物的活性是苯基丁a的三至五倍。
