of methanol. In the second and final step, compounds 3a-l were refluxed with phenyl-hydrazine to achieve the target compounds (E)-5-methyl-2-phenyl-3-(thiophen-2-yl)-7-(thiophen-2-ylmethylene)-3,3a,4,5,6,7-hexahydro-2H-pyrazolo[4,3-c]pyridine and their analogs (5a-l) in good yield. These compounds were used to assess their inflammation regulation properties in macrophages by executing quantitative pro-inflammatory
本文简要介绍了为合成,表征和开发(E)-5-甲基-2-苯基-3-(噻吩-2-基)-7-(噻吩-2-基亚甲基)-3,3a,4所做的努力,5,6,7-六氢-2H-吡唑并[4,3-c]吡啶及其类似物。在两步反应中,第一步是通过搅拌反应合成(3Z,5E)-1-甲基-3,5-双(噻吩-2-基亚甲基)哌啶-4-酮衍生物(3a-1)甲醇存在下1-甲基哌啶-4-酮和取代噻吩-甲醛的混合物。在第二个也是最后一个步骤中,化合物3a-1与苯基肼一起回流,以实现目标化合物(E)-5-甲基-2-苯基-3-(噻吩-2-基)-7-(噻吩-2 (-亚甲基)-3,3a,4,5,6,7-六氢-2H-吡唑并[4,3-c]吡啶及其类似物(5a-1),收率很高。通过分别执行定量促炎和抗炎蛋白(例如TNF-α,IL-1β,IL6和IL-10),这些化合物可用于评估巨噬细胞中的炎症调节特性。电子和体外COX-2抑制研究有助于了解化合物
