of the derivatives has been studied. Mechanism studies of the most promising compounds 14b and 15a were carried out. The results indicated that 14b and 15a could induce apoptosis, cell cycle arrest at the S phase and led to mitochondrial dysfunction in the HepG2 and PC-3 cell lines, respectively. Furthermore, Human Apoptosis Protein Array kit assay demonstrated that 14b could induce apoptosis through
为了探索一种高效,低毒的新型抗肿瘤药,合成了一系列NO供体的黄cut素衍生物(14-17),并评估了其对MCF-7,HCT-116,PC-3和HepG2癌细胞系的抗增殖活性。 。其中,化合物14b最强,IC50值分别为2.96μM,7.25μM,0.09μM和0.50μM,并且对正常人肝L-O2细胞显示出低毒性,IC50为47.96μM,显示出与正常人之间良好的选择性。和恶性肝细胞。此外,已经研究了衍生物的NO释放能力。进行了最有希望的化合物14b和15a的机理研究。结果表明,14b和15a分别可诱导HepG2和PC-3细胞凋亡,诱导S期细胞周期停滞并导致线粒体功能障碍。此外,人类凋亡蛋白阵列试剂盒检测结果表明14b可以通过下调procaspase-3的水平并抑制survivin,c-IAP1,HSP27,HSP60,HSP70,HO-1 / HMOX1 / HSP32和HO的表达来诱导细胞凋亡。
