  of targeted tyrosine kinase inhibitors capable of inhibiting KIT-driven proliferation, diverse mutations to this kinase drive resistance to established therapies.

  尽管通过应用能够抑制KIT驱动的增殖的靶向酪氨酸激酶抑制剂，胃肠道间质瘤（GIST）的治疗发生了革命性变化，但该激酶的多种突变却驱动了对既定疗法的耐药性。在这里，我们描述了有效的pan-KIT突变激酶抑制剂的鉴定，该抑制剂可以在不受多靶点药物所见的耐受性问题限制的情况下给药。这项工作致力于通过使用基于结构的设计来鉴定和优化现有激酶支架。从一系列先前报道的酪氨酸激酶PDGFRα的基于苯氧基喹唑啉和喹啉的抑制剂开始，优化了针对多种突变KIT驱动的Ba / F3细胞系的效能，特别着重于降低针对KDR驱动的细胞模型的活性，以限制二线和三线GIST治疗中常见的高血压可能性。AZD3229展示了在宽细胞面板上有效的一位数nM生长抑制作用，对KDR驱动的作用有良好的余地。可以通过水分子与活性位点中的蛋白质和配体的相互作用来合理地选择对KDR的选择性，并且它的动蛋白选择性类似于已获批准的GIST试剂中最好
