switch to allow hepatitis virus to enter hepatic cells. As the entry receptor protein of hepatitis virus, NTCP is also an effective target for the treatment of hepatocellular carcinoma. Herein, twenty-five benzamide analogues were synthesized based on the virtual screening design and their anti-proliferative activities against HepG2 cells were evaluated in vitro. Compound 35 was found to be promising
牛磺胆酸钠共转运多肽(NTCP)在肝炎的发展中起重要作用,并充当允许肝炎病毒进入肝细胞的开关。作为肝炎病毒的进入受体蛋白,NTCP也是治疗肝细胞癌的有效靶标。在此,基于虚拟筛选设计合成了二十五个苯甲酰胺类似物,并在体外评估了它们对HepG2细胞的抗增殖活性。发现化合物35很有前景,其IC 50值为2.8μM。35诱导的细胞凋亡其特征是通过调节标记,包括增加Bax,裂解的caspase 3和裂解的PARP蛋白,以及减少Bcl-2蛋白。分子对接和分子动力学(MD)模拟证实,化合物35可以与NTCP紧密结合。蛋白质印迹分析还表明,NTCP被抑制。总而言之,这些结果表明化合物35充当新型NTCP抑制剂以诱导HepG2细胞中的细胞凋亡。
