制备方法与用途

用途

4-氨基-3-氟苯羧酸甲酯是一种羧酸酯类衍生物,可用作医药中间体。

制备 第一步:酯化反应

采用4-硝基-3-氟苯甲酸、甲醇、苯和酸催化剂作为原料进行酯化反应。加热蒸出生成的水,直至不再有水馏出时表明反应结束。随后蒸发过量的甲醇和苯,并将溶液冷却。产物用自来水和10%NaHCO3水溶液洗涤至pH值为7左右。最后通过减压蒸馏收集112-114℃的馏分,得到4-硝基苯甲酸甲酯。

第二步:加氢还原反应

使用甲醇、4-硝基-3-氟苯甲酸甲酯和雷尼镍作为催化剂进行加氢还原反应。密封高压反应釜并置换空气后,启动搅拌器并升温。加氢至不再吸氢时反应结束。过滤出雷尼镍催化剂,并从滤液中回收甲醇。收集108-110℃的馏分,即为4-氨基-3-氟苯甲酸甲酯。

    发现高活性非胆汁酸FXR激动剂Tropifexor(LJN452),用于治疗胆汁淤积性肝病和非酒精性脂肪性肝炎(NASH)
    摘要:
    法尼醇X受体(FXR)是一种核受体,可作为胆汁酸代谢和信号转导的主要调节剂。FXR的激活抑制胆汁酸的合成并增加胆汁酸的结合,转运和排泄,从而保护肝脏免受胆​​汁积聚的有害影响,从而导致人们对FXR作为治疗胆汁淤积和非酒精性脂肪性肝炎的治疗靶标产生了浓厚的兴趣。我们确定了一系列新型的强效非胆汁酸FXR激动剂,该激动剂可将双环的奥氮平取代的苯并噻唑羧酸部分引入三取代的异恶唑支架上。在此,我们报告1的发现(tropifexor,LJN452),一种新型且高效的FXR激动剂。通过测量各种组织中FXR靶基因的诱导,在啮齿类动物PD模型中证明了体内活性很强。Tropifexor已进入NASH和PBC患者的2期人类临床试验。
