new 4(1H)-quinazolinones were synthesized and evaluated in the carrageenin-induced paw edema test. Most of the compounds were obtained by the cyclization of the appropriately substituted anthranilamides with acid chlorides, followed by further chemical transformation. Structure-activity data suggest that 2-isopropyl-1-phenyl-, 2-cyclopropyl-1-phenyl-, and 1-isopropyl-2-phenyl-4(1H)-quinazolinones afford
合成了许多新的4(1H)-喹唑啉酮,并在角叉菜胶诱导的爪水肿试验中进行了评估。大多数化合物是通过将适当取代的邻氨基苯甲酰胺与酰氯环合,然后进一步化学转化而获得的。结构活性数据表明2-异丙基-1-苯基-,2-环丙基-1-苯基-和1-异丙基-2-苯基-4(1H)-喹唑啉酮具有最佳效价,卤素原子的存在为首选活动。肾上腺切除术不影响抗炎测试结果。1-异丙基-(2-氟苯基)-4-(1H)-喹唑啉酮(50)显示出兼顾功效和副作用的最佳结果。
