the prepared compounds were screened for their in vitro COX-1/COX-2 inhibitory activities and in vivo anti-inflammatory activity. The most active anti-inflammatory derivatives, 4f-4i, after 3, 5 & 7 h were further subjected to histopathological and histochemical studies showing safe effect on gastric mucosa, especially 4h derivative. To explore the mechanism of action of COX-2 inhibitory compounds 4f
合成了带有甲磺酰胺部分的新型查耳酮3a-c、吡唑啉4a-i和吡啶5a-c、6a&b衍生物。使用光谱数据和元素分析证实了它们的构造。通过 MM2 性质和1 H NMR 谱预测了化合物3a-c的立体化学构型。筛选所有制备的化合物的体外COX-1/COX-2抑制活性和体内抗炎活性。最活跃的抗炎衍生物4f-4i,在3、5和7小时后进一步进行组织病理学和组织化学研究,显示对胃粘膜的安全作用,特别是4h衍生物。为了探索SI 值最高的COX-2 抑制化合物4f和6b的作用机制,将它们对接在 COX-2 活性位点内。预测了4f-i和6b衍生物的理化性质,并与参考药物塞来昔布进行了比较。它们表现出良好的口服生物利用度,特别是吡唑啉衍生物4f和含吡啶的化合物6b。
