Starting from isatoic anhydrides, several new 2,3‐dihydroquinazolin‐4(1H)‐one derivatives bearing chalcone or pyrazole or thiazole moieties at the third position were synthesized. The analgesic and anti‐inflammatory activities for most compounds were studied at a dose level of 50 mg/kg via the acetic‐acid‐induced writhing‐response method and carrageenan‐induced edema method, respectively. The study
以靛红酸酐为原料,合成了几种在第三位带有查耳酮或吡唑或噻唑部分的新型 2,3-二氢喹唑啉-4 (1H)-one 衍生物。分别通过醋酸诱导的扭体反应法和角叉菜胶诱导的水肿法在 50 mg/kg 的剂量水平下研究了大多数化合物的镇痛和抗炎活性。研究表明,带有 4-氯苯基 4c 或 4-硝基苯基 4b 的查耳酮作为镇痛药的活性最强。查耳酮 4c 和带有 4-甲氧基苯基 5b 的 N-苯基吡唑均显示出比塞来昔布更高的抗炎活性,但仍低于双氯芬酸钠。此外,查耳酮 4c 具有与选择性环氧合酶 2 抑制剂塞来昔布几乎相同的致溃疡指数。
