the aim of developing dual inhibitors of multidrug-resistant tuberculosis and inflammation. The in vivo anti-inflammatory activity results showed excellent inhibition of rat paw edema. The methoxybenzene/nitrofuryl derivative of title compounds showed 83% inhibition of inflammation during 2–6 h after carrageenan injection. All compounds showed anti-tuberculosis activity at MIC of 50 µg/cm3. The molecular
摘要一系列3- [5-硝基(呋喃/噻吩)-2-基] -1-芳基-3-(5-芳基1,3,4-恶二唑-2-基硫基)丙-2-烯-1为了开发耐多药结核病和炎症的双重抑制剂,合成并研究了一种衍生物。体内抗炎活性结果显示对大鼠爪水肿具有极好的抑制作用。角叉菜胶注射后2–6 h,标题化合物的甲氧基苯/硝基呋喃基衍生物显示出83%的炎症抑制作用。所有化合物在MIC为50 µg / cm 3时均显示出抗结核活性。分子对接研究表明,恶二唑和硝基呋喃基团通过与Tyr 385,Ser 530,Tyr 467和Tyr 158氨基形成氢键,在COX1,COX2、5-LOs和InhA酶的抑制位点中起重要作用。酸残基。新化合物是对大肠杆菌具有潜在抑制作用的活性抗菌剂。毒性结果显示人肾细胞系具有良好的存活率,其IC 50值大于100 µg / cm 3浓度。化合物的Hirshfeld表面分析和静电势图显示出良好的分子间接触以及氢键供体和受体的电势。
