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。
