  摘要：

  尽管克唑替尼在间变性淋巴瘤激酶（ALK）阳性的非小细胞肺癌患者中显示出强大的疗效，但最终仍会在治疗过程中发展。抗药性患者样品显示ALK激酶结构域中存在多种点突变，包括L1196M网守突变。另外，一些患者由于脑癌转移而进展。使用基于结构的药物设计，亲脂性效率和基于物理性质的优化，制备了具有强吸收，分布，代谢和排泄（ADME），p-糖蛋白1介导外排倾向低的高效大环ALK抑制剂，以及良好的被动渗透性。这些结构异常的大环抑制剂对野生型ALK和临床报道的ALK激酶结构域突变有效。克服了重大的合成挑战，利用新颖的转化方法使这些大环化合物能够用于药物发现范例中。这项工作导致发现8k（PF-06463922），结合了广谱效能，中枢神经系统ADME和高度的激酶选择性。

  therapeutics. We used molecular modeling-assisted structural optimization starting with the low micromolar potency compound 9 to discover compound 13c, a highly potent and orally bioavailable Axl inhibitor. Selectivity profiling showed that 13c could inhibit the well-known oncogenic kinase Met with equal potency to its inhibition of Axl superfamily kinases. Compound 13c significantly inhibited cellular Axl and

  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。
