A new series of 2,4-dianilino-5-fluoropyrimidine derivatives were designed and synthesized and their anaplastic lymphoma kinase (ALK) inhibitory activities were evaluated by biochemical and cell-based assays in order to discover a new ALK inhibitor. Most compounds synthesized showed good inhibitory activities against ALK and good cytotoxic activities in H3122 cell line. The best compound 6f showed good activity against wild-type ALK along with crizotinib-resistant mutant ALK, and it showed 6 times better activity in cell-based assay than crizotinib. Some SAR studies were performed by the comparisons of the activities between 6 and the designed-synthesized compounds.
为了发现一种新的 ALK 抑制剂,我们设计并合成了一系列新的 2,4-二苯胺基-5-氟嘧啶衍生物,并通过生化和细胞试验评估了它们对无性淋巴瘤激酶(ALK)的抑制活性。合成的大多数化合物对 ALK 具有良好的抑制活性,并对 H3122 细胞株具有良好的细胞毒性。最好的化合物 6f 对野生型 ALK 和克唑替尼耐药突变型 ALK 都表现出了良好的活性,在基于细胞的检测中,它的活性是克唑替尼的 6 倍。通过比较 6 和设计合成的化合物的活性,进行了一些 SAR 研究。
