progression during treatment eventually develops. Resistant patient samples revealed a variety of point mutations in the kinase domain of ALK, including the L1196M gatekeeper mutation. In addition, some patients progress due to cancer metastasis in the brain. Using structure-based drug design, lipophilic efficiency, and physical-property-based optimization, highly potent macrocyclic ALK inhibitors were prepared
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。
