Combination of anaplastic lymphoma kinase (ALK) inhibitor with histone deacetylases (HDAC) inhibitor could exert synergistically anti-proliferative effects on ALK positive non-small cell lung cancer (NSCLC) naïve or resistant cells. In this work, we designed and synthesized a series of 2,4-pyrimidinediamine derivatives as dual ALK and HDAC inhibitors based on pharmacophore merged strategy. Among which
间变性淋巴瘤激酶 (ALK) 抑制剂与组蛋白去乙酰化酶 (HDAC) 抑制剂的组合可以对 ALK 阳性非小细胞肺癌 (NSCLC) 幼稚或耐药细胞产生协同抗增殖作用。在这项工作中,我们基于药效团合并策略设计并合成了一系列 2,4-嘧啶二胺衍生物作为 ALK 和 HDAC 双重抑制剂。其中,化合物10f 分别对 ALK (IC 50 = 2.1 nM) 和 HDAC1 (IC 50 = 7.9 nM)显示出最有效且平衡的抑制活性。特别是,10f对经常观察到的克唑替尼耐药 ALK L1196M也有效(IC 50 = 1.7 nM) 以及耐色瑞替尼的 ALK G1202R (IC 50 = 0.4 nM) 突变体。在抗增殖活性测定中,10f在低微摩尔浓度下对 ALK 成瘾的癌细胞系表现出令人印象深刻的活性,这与克唑替尼和色瑞替尼相当。进一步的流式细胞术分析表明,10f可以通过细胞凋亡和细胞
