B-RafV600E was an effective target for the treatment of human cancers. Based on a pan-Raf inhibitor TAK-632, a series of N-(4-aminopyridin-2-yl)amide derivatives were designed as novel B-RafV600E inhibitors. Detailed structure–activity studies of the compounds revealed that most of the compounds displayed potent enzymatic activity against B-RafV600E, and good selectivity over B-RafWT. One of the most promising
B-Raf V600E是治疗人类癌症的有效靶标。基于泛Raf抑制剂TAK-632,设计了一系列N-(4-氨基吡啶-2-基)酰胺衍生物作为新型B-Raf V600E抑制剂。化合物的详细结构活性研究表明,大多数化合物对B-Raf V600E均具有强大的酶促活性,并且具有优于B-Raf WT的选择性。最有前途的化合物4l之一显示出对B-raf V600E的有效抑制活性,IC 50值为38 nM ,并且对具有IC 50的colo205和HT29细胞显示出抗增殖活性值分别为0.136和0.094μM。在B-Raf WT的酶法和细胞分析中,它也显示出良好的选择性。这些抑制剂可用作进一步开发新型B-Raf V600E抑制剂作为抗癌药物的先导化合物。
