制备方法

1. 反应步骤一：

   • 向三口瓶中加入2-氨基吡啶溶液（10 mmol）0.94 mL、DMF（20 mmol）3.4 mL 和 10 mL 异丙醇，搅拌均匀。
   • 然后在水浴中加热至65 ℃，反应2小时。
   • 反应结束后，将溶剂蒸发，得到中间体。

2. 反应步骤二：

   • 将中间体溶解于10 mL DMF 中，加入15 mmol 碳酸钠饱和溶液和 15 mmol 溴乙酸乙酯，搅拌均匀。
   • 加热到85 ℃。反应完成后用薄层色谱进行检测，然后使用无水硫酸钠干燥，并减压浓缩。
   • 使用硅胶柱色谱法分离粗产品，淋洗液采用乙酸乙酯/正己烷（1∶6），得到纯品咪唑[1,2-A]吡啶-3-甲酸乙酯。

3. 反应步骤三：

   • 将咪唑[1,2-A]吡啶-3-甲酸乙酯加入氢氧化钾的乙醇溶液（10.1 g 氢氧化钾，73 mL 乙醇）中。
   • 加热至回流，反应1小时，并用薄层色谱(TLC)检测反应情况。
   • 反应完毕后，浓缩反应液，加50 mL 水，用浓盐酸调节pH值至2。
   • 进行乙酸乙酯萃取，合并有机相并用饱和食盐水洗涤。最后使用硫酸钠固体干燥并减压浓缩，得到化合物咪唑[1,2-A]吡啶-3-甲酸。

  通过取代铰链结合剂部分发现有效的集落刺激因子1受体抑制剂

  摘要：

  肿瘤相关的巨噬细胞（TAM）主要与肿瘤的生长有关。集落刺激因子1受体（CSF1R）充当TAM存活和分化的关键调节剂，并且是癌症治疗的分子靶标。本文中，通过铰链结合部分的替代策略鉴定了新型CSF1R抑制剂。咪唑并[1,2- a ]吡啶（49）或吡唑并[1,5- a ]吡啶（50）作为铰链粘合剂的引入在酶法测定中对CSF1R在10 nM抑制率分别为87％和82％。 IC 50在MNFS60单元中分别为25 nM和27 nM的值。这些衍生物显着抑制细胞中的CSF1R磷酸化。我们的方法可以用作发现新型激酶抑制剂的策略。
