  发现嘧啶二酮衍生物作为有效且口服生物可利用的 Axl 抑制剂

  摘要：

  受体酪氨酸激酶 Axl 在促进癌症进展、转移和耐药性中发挥重要作用，并已被确定为抗癌治疗的有希望的靶点。我们从低微摩尔效力化合物9开始，使用分子建模辅助结构优化来发现化合物13c ，这是一种高效且可口服生物利用的 Axl 抑制剂。选择性分析表明， 13c可以抑制众所周知的致癌激酶 Met，其抑制 Axl 超家族激酶的效力相同。化合物13c显着抑制细胞Axl和Met信号传导，抑制Axl和Met驱动的细胞增殖，并抑制Gas6/Axl介导的癌细胞迁移或侵袭。此外， 13c在 Axl 驱动和 Met 驱动的肿瘤异种移植模型中表现出显着的抗肿瘤功效，在耐受良好的剂量下导致肿瘤停滞或消退。所有这些有利的数据使13c成为癌症治疗的有前途的候选药物。

• Streamlined Synthesis of Diaminopyridines by Pd‐Catalyzed Ammonia Coupling with Deactivated Amino‐Chloropyridines
  作者：Florian Bourriquen、Antoine Bruneau‐Voisine、Aliénor Jeandin、Etienne Stihle、Serena Fantasia

  DOI：10.1002/chem.201902147

  日期：2019.7.5

  synthetic strategy is the development of an unprecedented palladium‐catalyzed coupling reaction of ammonia with chloropyridines deactivated by the presence of an alkylamino substituent. The coupling reaction was accomplished with very low catalyst loadings under remarkably mild reaction conditions, making the system particularly suitable for both academic and industrial applications. The utility of this methodology

  据报道，高效，经济的两步合成二氨基吡啶是生物活性化合物的基本组成部分。与以前报道的路线相比，其优势包括溴-氯吡啶起始原料的成本和更广泛的可得性，以及可直接获得的扩展的二氨基吡啶区域异构体阵列。该合成策略的关键推动力是开发前所未有的钯催化氨与氯吡啶的偶合反应，该烷基吡啶因存在烷基氨基取代基而失活。偶联反应是在非常温和的反应条件下以极低的催化剂负载量完成的，因此该系统特别适用于学术和工业应用。
