A new series of 3-(((9H-purin-6-yl)amino)methyl)-4,6-dimethylpyridin-2(1H)-one derivatives were designed, synthesized and demonstrated to act as tubulin polymerization inhibitors. These new derivatives showed significant antitumor activities, among which SKLB0533 demonstrated to be the most potent compound, with IC50 values ranging from 44.5 to 135.5 nM against seven colorectal carcinoma (CRC) cell
设计,合成并证明了新的3-(((9H-嘌呤-6-基)氨基)甲基)-4,6-二甲基吡啶-2(1H)-one衍生物可作为微管蛋白聚合抑制剂。这些新的衍生物显示出显着的抗肿瘤活性,其中SKLB0533被证明是最有效的化合物,针对7种结直肠癌(CRC)细胞系的IC50值为44.5至135.5 nM。值得注意的是,SKLB0533没有表现出对其他潜在靶标的活性,例如420种激酶和EZH2。此外,SKLB0533抑制微管蛋白聚合,使细胞周期停在G2 / M期并诱导CRC细胞凋亡。此外,SKLB0533抑制了HCT116异种移植模型中的肿瘤生长,而没有引起明显的主要器官相关毒性,
