New quinoline compounds comprising pyrazole scaffold through different amide linkages were synthesized. The synthesized compounds were evaluated for their anti-inflammatory activity. Eight compounds (5c, 11b,c, 12c, 14a,b, 20a and 21a) were found to exhibit promising anti-inflammatory profiles in acute and sub-acute inflammatory models. They were screened for their ulcerogenic activity and none of
合成了包含通过不同酰胺键的吡唑支架的新喹啉化合物。评价合成的化合物的抗炎活性。发现了八种化合物(5c,11b,c,12c,14a,b,20a和21a)在急性和亚急性炎症模型中显示出有希望的抗炎特性。对它们的致溃疡活性进行了筛选,没有一个与参考药物塞来昔布相比具有显着的致溃疡活性,并且实验动物对它们具有很好的耐受性,并具有较高的安全系数(ALD 50 > 0.3 g / kg)。化合物5c,11b,c,图12c,14a,b,20a和21a显示出显着的体外LOX抑制活性,高于齐留通。体外COX-1 / COX-2抑制研究表明,化合物12c,14a,b和20a对COX-2的选择性高于对COX-1的选择性。在测试的化合物中,具有IC 50的12c,14a和14b表现出对COX-2的最高抑制活性分别为0.1、0.11和0.11μM。对接实验试图推测COX-2酶结合位点中活性最高的化合物的结合模式,
