A new series of compounds comprising of 2,5-diaryl-1,3,4-oxadiazoles was synthesized and evaluated as potential COX-2 inhibitors. Compounds 6b, 6e, 6f, 7e and 7f were found to be the most potent and selective inhibitors of COX-2 (IC50 = 0.48–0.89 μM; SI = 67.96–132.83). Compounds 6e, 6f and 7f displayed anti-inflammatory activity superior to celecoxib in a carrageenan-induced rat paw edema assay. Structure–activity
合成了一系列新的包含2,5-二芳基-1,3,4-恶二唑的化合物,并将其评估为潜在的COX-2抑制剂。发现化合物6b,6e,6f,7e和7f是最有效和选择性的COX-2抑制剂(IC 50 = 0.48–0.89μM; SI = 67.96–132.83)。化合物6e,6f和7f在角叉菜胶诱导的大鼠爪水肿试验中显示出优于塞来昔布的抗炎活性。结构-活性关系分析表明,具有甲基磺酰基部分的化合物可导致对COX-2的更多选择性抑制,这在分子对接研究中得到了很好的支持。在RAW 264.7和J774A.1细胞中对最有效化合物的细胞毒性研究表明,以30μM的浓度进行测试时,细胞活力超过89%。
