制备方法与用途

用途

6-氧代-1,6-二氢吡啶-2-羧酸甲酯是一种重要的医药中间体和精细化工原料，应用范围广泛，市场前景广阔。在医药领域中，作为重要医药中间体的2-吡啶甲醇可以用来合成替硝唑，也可以用于合成有机磷酸酯类解毒药解磷定。

制备方法

在250毫升三颈瓶中加入80毫升甲醇，然后缓慢滴加1.0毫升浓硫酸，室温下回流反应30小时（通过TLC跟踪）。反应完成后，浓缩至约30毫升后倒入60毫升水中，用20毫升乙醚萃取两次。乙醚层依次用5%碳酸钠溶液洗涤一次和水洗至中性，再经无水硫酸镁干燥后蒸去乙醚得到目标产物6-氧代-1,6-二氢吡啶-2-羧酸。

  摘要：

  Autotaxin（ATX）是一种分泌的酶，负责将溶血磷脂酰胆碱（LPC）水解为生物活性溶血磷脂酸（LPA）和胆碱。ATX-LPA信号通路与细胞存活，迁移和增殖有关。因此，抑制ATX是许多疾病的公认治疗靶标，包括纤维化疾病，癌症和炎症等。许多已开发的ATX合成抑制剂与天然配体的脂质化学型相似。然而，已经描述了少数与该普通支架不同的抑制剂。在本文中，我们报告了先前报道的小分子ATX抑制剂的结构-活性关系（SAR）。通过酶动力学研究表明，这种化学型的类似物是非竞争性抑制剂，
