A series of benzo[d]thiazole analogs were synthesized and evaluated for their anti-inflammatory and analgesic effects. Using an ear edema model, except for compounds 2k, 2m-2q and 3a, other compounds showed the anti-inflammatory effects. Among them, compounds 2c, 2d, and 2g showed the best anti-inflammatory activity (inhibition rate: 86.8%, 90.7% and 82.9%, respectively). By the acetic acid-induced
合成了一系列苯并[ d ]噻唑类似物,并评估了它们的抗炎和镇痛作用。使用耳部水肿模型,除了化合物2k,2m - 2q和3a以外,其他化合物均显示出抗炎作用。其中,化合物2c,2d和2g表现出最佳的抗炎活性(抑制率分别为86.8%,90.7%和82.9%)。通过乙酸诱发的腹部扭体试验,化合物2e,2l,2m,2o,2p和3a除外,其他化合物具有镇痛作用,抑制率分别为51.9–100%(2a-2r)和68.6–100%(3a-3g)。接下来,评价显示出优异的抗炎和止痛活性的化合物2c,2d,2g,3d,3f,3g对绵羊COX-1和COX-2的抑制作用。化合物2c,2d,2g,3d,3f,3g是弱的COX-1同工酶抑制剂,但表现出中等的COX-2同工酶抑制作用IC 50从0.28至0.77μM和COX-2选择性指数(SI:18.6至7.2)。该苯并[ d ]噻唑部分将被证明对开发更有效的COX-2抑制剂具有重要意义。
