COX‐2 inhibitory activity with IC50 values of 0.19, 0.11, and 0.24 μM, respectively. The synthesized compounds with the highest COX‐2 selectivity indices were evaluated for their anti‐inflammatory, analgesic, and ulcerogenic activities. Compounds 6a and 16a demonstrated the most potent and consistent anti‐inflammatory activity over the synthesized compounds, which was significantly higher than that of
合成了一些新的 2,6-二取代哒嗪-3(2H)-one 衍生物并评估了体外环氧化酶-2 (COX-2) 抑制功效。化合物 2-[3-(2-methylphenoxy)-6-oxopyridazin-1(6H)-yl]methyl}-1H-isoindole-1,3(2H)-dione (5a), 2-propyl-6-(邻甲苯氧基)哒嗪-3(2H)-酮(6a)和2-苄基-6-(3,5-二甲基-1H-吡唑-1-基)哒嗪-3(2H)-酮(16a)显示最有效的 COX-2 抑制活性,IC50 值分别为 0.19、0.11 和 0.24 μM。评估了具有最高 COX-2 选择性指数的合成化合物的抗炎、镇痛和致溃疡活性。与合成化合物相比,化合物 6a 和 16a 表现出最有效和一致的抗炎活性,
