A series of 1,5‐diaryl‐1,2,4‐triazole derivatives were synthesized and evaluated as cyclooxygenase‐2 (COX‐2) inhibitors. The results of the preliminary biological assays in vivo showed that eight compounds 5b, 6b, 6c, 7c, 8b, 8d, 9c, and 9d have potent anti‐inflammatory activity (P < 0.01), while compounds 6b, 6c, and 9c exhibit marked potency. Compound 6c was then selected for further investigation
合成了一系列 1,5-二芳基-1,2,4-三唑衍生物,并评估其作为环氧合酶-2 (COX-2) 抑制剂。体内初步生物学测定结果表明,8种化合物5b、6b、6c、7c、8b、8d、9c和9d具有强效抗炎活性(P<0.01),而化合物6b、6c和9c则表现出强效抗炎活性(P<0.01)。显着效力。然后选择化合物 6c 进行进一步研究。在体外 COX 抑制试验中,化合物 6c 被鉴定为 COX-2 的有效选择性抑制剂(COX-2 IC50 = 0.37 µM;SI = 0.018),与塞来昔布(COX-2 IC50 = 0.26 µM;SI)等效= 0.015)。在大鼠角叉菜胶诱导的爪水肿试验中,6c 在以 15 mg/kg 口服给药后 2 小时表现出中等抗炎活性(炎症抑制 35%)。
