9, 10–14 and 16–18 showed higher activity compared to doxorubicin as a positive control. The radiosensitizing ability of the most promising compounds 4, 10 and 12 was studied which showed an increase in the cell killing effect of γ-radiation after combination with these derivatives. The molecular design was performed to predict the binding mode of the most promising compounds 4, 10 and 12 with the
从战略原料(E)-4-氯代N-(4-(1-(2-(2-(2-(2-氰基乙酰基)肼基)乙基)苯基)苯磺酰胺4开始合成了一系列新的磺酰胺衍生物4-21。获得了两个带有磺酰胺部分的series 5-9和吡啶酮10-21衍生物。评价所有新合成的化合物对人肝癌细胞系(HepG2)的体外细胞毒活性。与作为阳性对照的阿霉素相比,化合物4-6、8、9、10-14和16-18显示出更高的活性。最有前途的化合物的放射增敏能力4,10和12进行了研究,其表明在γ辐射与这些物质的衍生物的组合后的细胞杀伤作用的增加。进行分子设计来预测最有前途的化合物的结合模式4中,10和12与HCA IX的活性位点,即显示出适当的配件与所述结合口袋的相关氨基酸的标准键长的基础上,角度,S得分和E构象数据。
