docking simulation for the most selective compounds 4a, 5b, 6a, and 7a inside COX-2 active site was performed to explain their binding mode. Finally, an ADME study was applied and proved the promising activity of the new compounds as a new oral anti-inflammatory agent. In conclusion, the above findings reveal that newly developed compounds 4a, 6a, and 7a represent a potential selective COX-2 NSAID candidate
设计并合成了四个新系列的1,2,4 三唑衍生物4a,b 5a-d, 6a-f和7a,b具有甲基磺酰基苯基部分作为COX-2 药效团。制备目标化合物并在体外针对 COX-1 和 COX-2 酶进行评估。与塞来昔布 (SI = . 6.44) 相比,化合物4a、5b、6a和7a对 COX-2 酶的选择性最高 (SI = 8.64–14.58)。有趣的是,相对于参比药物塞来昔布(49.60%),化合物4a、6a和7a在 3 小时后表现出良好的抗炎活性和水肿抑制作用(依次为 54.17、53.03 和 50.29%)。此外,这些强效衍生物与参考药物塞来昔布(UI = 2.99)和消炎痛(UI = 20.25)相比,4a、5b、6a和7a的溃疡性(UI = 2.27-2.97)显着降低。此外,还包括胃的组织病理学研究。此外,对COX-2活性位点内最具选择性的化合物4a、5b、6a和7a进行了对接模拟,以解释它们的结合模式。最后,一项
