2,7-disubstituted-thieno[3,2-d]pyrimidine derivatives were designed, synthesized and evaluated as novel focal adhesion kinase (FAK) inhibitors. The novel 2,7-disubstituted-thieno[3,2-d]pyrimidine scaffold has been designed as a new kinase inhibitor platform that mimics the bioactive conformation of the well-known diaminopyrimidine motif. Most of the compounds potently suppressed the enzymatic activities
设计,合成和评价了一系列的2,7-二取代-噻吩并[3,2-d]嘧啶衍生物,作为新型的粘着斑激酶(FAK)抑制剂。新型的2,7-二取代-噻吩并[3,2-d]嘧啶骨架已被设计为一种新的激酶抑制剂平台,可模仿众所周知的二氨基嘧啶基序的生物活性构象。大多数化合物有效抑制FAK的酶活性,并有效抑制U-87MG,A-549和MDA-MB-231癌细胞系的增殖。在这些衍生物中,优化的化合物26f在U-87MG,A-549和MDA-MB-231细胞中均能有效抑制酶(IC50 = 28.2 nM),并显示出比TAE-226更强的效力,IC50值为0.16、0.27,和0.19μM。化合物26f还具有相对较低的细胞毒性(IC50 = 3)。32μM)朝向正常人细胞株HK2。根据流式细胞术结果,化合物26f以剂量依赖性方式诱导MDA-MB-231细胞的凋亡,并有效地将MDA-MB-231细胞阻滞在G0 / G1
