The synthesis and the pharmacological activity of a series of 1,5-diarylimidazoles developed as potent and selective cyclooxygenase-2 (COX-2) inhibitors are described. The new compounds were evaluated both in vitro (COX-1 and COX-2 inhibition in human whole blood) and in vivo (carrageenan-induced paw edema, air-pouch, and hyperalgesia tests). Modification of all the positions of two regioisomeric imidazole
描述了开发为有效和选择性环氧合酶2(COX-2)抑制剂的一系列1,5-二芳基咪唑的合成和药理活性。在体外(在人全血中对COX-1和COX-2的抑制)和在体内(对角叉菜胶引起的爪水肿,气袋和痛觉过敏测试)均对新化合物进行了评估。修饰两个区域异构咪唑核的所有位置导致鉴定出最佳的4- [4-氯-5-(3-氟-4-甲氧基苯基)咪唑-1-基]苯磺酰胺(UR-8880,51f)候选者,目前正在进行I期临床试验。
