制备方法与用途

简介

2-溴-4-甲基-5-硝基吡啶是一种医药中间体。该化合物可通过先对2-溴-4-甲基-5-硝基吡啶进行硝化反应制备4-甲基-5-硝基-2-氨基吡啶，再通过重氮化反应进一步合成得到目标产物。此外，2-溴-4-甲基-5-硝基吡啶也可用于制备GPR受体激动剂，如1-(1-(5-乙基嘧啶-2-基)哌啶基-4-基)-5-(4-(甲基磺酰)苯基)-1氢-吡咯并[2,3-c]吡啶。

用途

2-溴-4-甲基-5-硝基吡啶作为一种吡啶类有机物，主要用作医药中间体。

  名称：

  通过构象约束发现（1H-吡唑并[3,4-c]吡啶-5-基）磺酰胺类似物作为乙型肝炎病毒衣壳装配调节剂。

  摘要：

  在临床前和临床研究中，均已建议乙型肝炎病毒（HBV）衣壳装配调节剂（CAMs）是有效的抗HBV药物。除了阻断HBV复制外，CAM还可以减少共价闭合环状DNA（cccDNA）的形成，这说明了HBV感染的持续性。在这里，我们通过限制氨基磺酰基苯甲酰胺衍生物的构象，描述了作为新的CAM化学型的（1 H-吲唑-5-基）磺酰胺和（1 H-吡唑并[3,4- c ]吡啶-5-基）磺酰胺的发现。 。铅优化导致化合物56的EC 50值为0.034μM，在小鼠肝微粒体中具有良好的代谢稳定性。为了增加溶解度，氨基酸前药（制备65）及其柠檬酸盐（67）。在基于水动力注射的HBV感染小鼠模型中，化合物67剂量依赖性地抑制HBV复制，而56则由于其次优溶解性而未显示体内抗HBV活性。这类化合物可作为开发新型抗HBV药物的起点。
