Axl 通常在许多癌症中过度表达,并与肿瘤生长、转移、耐药性和较差的总体生存率相关,因此已成为癌症治疗的一个有前景的靶点。然而,用于 Axl 抑制的新化学形式的可用性是有限的。在此,我们介绍了新型 Axl 抑制剂的开发和表征,包括一系列二苯基嘧啶二胺衍生物的设计、合成和构效关系 (SAR)。这些化合物中的大多数都表现出显着的抗 Axl 激酶活性。特别是,有前途的化合物m16显示出最高的酶抑制效力(IC 50 = 5 nM)并阻断多种肿瘤细胞的增殖效力( 42 个癌细胞系中 4 个的CC 50 <100 nM)。此外,化合物m16还具有较好的药代动力学特征和肝微粒体稳定性。所有这些有利的结果使m16成为进一步开发的良好领先治疗候选药物。
