A series of 7H-pyrrolo[2,3-d]pyrimidine derivatives possessing a dimethylphosphine oxide moiety were designed, synthesized and evaluated as novel Focal adhesion kinase (FAK) inhibitors. Most compounds potently suppressed the enzymatic activities of FAK, with IC50 values in the 10-8-10-9 M range, and potently inhibited the proliferation of breast (MDA-MB-231) and lung (A549) cancer cell lines. The representative
设计,合成和评估了一系列具有二甲基氧化膦部分的7H-吡咯并[2,3-d]嘧啶衍生物,作为新型的Focal粘附激酶(FAK)抑制剂。大多数化合物有效抑制FAK的酶活性,IC50值在10-8-10-9 M范围内,并有效抑制乳腺癌(MDA-MB-231)和肺癌(A549)癌细胞系的增殖。当在一组26种激酶上测试时,代表性化合物25b表现出有效的酶抑制作用(IC50 = 5.4 nM)和良好的选择性。25b表现出对A549细胞的抗增殖活性(IC50 = 3.2μM),并且对正常人细胞株HK2的细胞毒性相对较小。化合物25b还诱导细胞凋亡并以浓度依赖性方式抑制A549细胞的迁移。化合物25b的进一步分析表明,它在体外的小鼠,大鼠和人肝微粒体中具有良好的代谢稳定性,并且对人细胞色素P450的各种亚型均显示出弱的抑制活性。进行化合物25b的对接研究是为了阐明其可能的结合方式,并为FAK抑制剂的进一步结构指导设计提供结构基础。
