momelotinib. In particular, the most promising compounds 9k and 13f showed the most potent antitumor activities with IC50 values of 2.14/1.98 μM, 3.59/2.78 μM, 5.52/4.27 μM, and 3.69/4.01 μM against A549, HCT-116, PC-3 and MCF-7 cell lines, respectively. Structure–activity relationship (SAR) studies were conducted based on the variation of the moiety of the aromatic ring and the terminal aniline on the
为了开发具有抗癌活性的新型治疗剂,设计并合成了两个系列的具有三唑哌嗪或1,4,8-三氮杂螺[4.5] decan-3-one支架的新型2,4-二氨基嘧啶衍生物。初步研究表明,与palbociclib和momelotinib相比,某些化合物对四种测试的癌细胞系表现出中等至优异的效力。特别是,最有前途的化合物9k和13f在IC 50中显示出最有效的抗肿瘤活性分别针对A549,HCT-116,PC-3和MCF-7细胞系的2.14 / 1.98μM,3.59 / 2.78μM,5.52 / 4.27μM和3.69 / 4.01μM值。基于芳香环和嘧啶核上末端苯胺部分的变化,进行了结构-活性关系(SAR)研究。此外,通过进一步探索其生物活性,阐明了其抗癌活性的机制。结果表明,化合物9k明显抑制A549细胞系的增殖,导致线粒体膜电位大大降低,导致癌细胞凋亡,抑制肿瘤细胞迁移并延长A549细胞周期分布,表示在G2处受阻-M期,在S期积累。
