Two series of twenty diversely substituted benzothiazole amides were designed and synthesized aiming to obtain derivatives with potential anti-inflammatory activity and decreased GIT ulceroginicity. All the synthesized compounds were in-vivo screened for their anti-inflammatory activity using carrageenan induced rat hind paw edema model. Results revealed that compounds 3h and 6a were the most potent

水肿模型对所有合成的化合物进行体内筛选其抗炎活性。结果显示,与
吲哚美辛相比,化合物3h和6a是最有效的化合物,具有显着的 GIT 耐受性(ED 50 分别为 0.012、0.016 和 0.015 mmol/kg)。此外,化合物3h和6a致溃疡研究证明,前 2 剂(0.01、0.02 mmol/kg)溃疡指数 = 0,仅 6a 就超过第三剂(0.03 mmol/kg )。体外COX-1/COX-2同工酶选择性测试显示,在所研究的化合物中,与
塞来昔布(SI=11.89)相比,化合物6a (SI=3.10)的选择性指数最佳,并通过分子对接研究进一步证实。
