为了寻找结构新颖、活性较强的抗肿瘤化合物,首次设计合成含异吲哚酮的5-氟嘧啶衍生物,16个化合物均为新化合物, 并用核磁共振波谱(NMR)和高分辨质谱(HRMS)等方法对化合物结构进行表征. 采用四甲基偶氮唑盐(MTT)法测定目标化合物对人B淋巴细胞(Raji)、人乳腺癌细胞(MCF-7)、人肝癌细胞(HepG2)、小鼠B细胞淋巴瘤细胞(A20)和人结肠癌细胞(HCT116)的抑制活性. 结果显示化合物6a对Raji细胞具有最强的抑制活性, IC50为1.56 μmol/L, 化合物6j对A20细胞具有最强的抑制活性, IC50为0.99 μmol/L, 化合物6j对HCT116细胞具有最强的抑制活性, IC50为3.21 μmol/L, 均优于阳性对照药Fostamatinib;化合物6l对MCF-7细胞具有最强的抑制活性, 优于阳性对照药Palbociclib, 其IC50为14.28 μmol/L; 化合物6j对HepG2细胞具有最强的抑制活性, 优于阳性对照药Sorafenib tosylate, IC50为5.01 μmol/L;

In order to search for new structural anti-tumor drugs, a series of novel 5-fluoropyrimidin derivatives containing isoindolin-1-one were synthesized for the first time and evaluated for their inhibitory activities against B lymphocyte(Raji), Human breast cancer cell(MCF-7), Human hepatoma carcinoma cells(HepG2), mouse B lymphoma(A20) and Human colon cancer cell(HCT116) by using MTT assay. 16 compounds reported herein were new compounds, these chemical structures were well characterized by nuclear magnetic resonance spectroscopy (NMR) and high-resolution mass spectra (HRMS) spectroscopic methods. Compound 6a showed the most potent inhibitory activity against Raji cells with the IC50 values of 1.56 μmol/L, compound 6j showed the most potent inhibitory activity against A20 cells, IC50 values of 0.99 μmol/L, compound 6j showed the most potent inhibitory activity against HCT116 cells with the IC50 values of 3.21 μmol/L, they were better than Fostamatinib. Compound 6l showed the most potent inhibitory activity against MCF-7 cells with the IC50 values of 14.28 μmol/L than Palbociclib. Compound 6j showed the most potent inhibitory activity against HepG2 cells with the IC50 values of 5.01 μmol/L than Sorafenib tosylate.
