To explore antitumor agents with potent efficacy and low toxicity, scutellarein derivatives with benzoic acid mustard (10a−c, 11a−c and 13a−c) were designed and synthesized. The antiproliferative activities of the target derivatives against A549, MCF-7 and Bel-7402 cancer cell lines were tested. Compound 10a showed the strongest potency with an IC50 value of 1.50 μM against MCF-7 cell line, and displayed
为了探索有效且低毒的抗肿瘤药,设计并合成了具有苯甲酸芥子气的黄cut苷衍生物(10a - c,11a - c和13a - c)。测试了目标衍生物对A549,MCF-7和Bel-7402癌细胞系的抗增殖活性。化合物10a对MCF-7细胞系的效能最强,IC 50值为1.50μM,对人肝L-O2正常细胞的毒性低(IC 50 > 50μM),显示了正常细胞与恶性细胞之间的特异性。机理研究表明10a它可能以浓度依赖的方式诱导MCF-7细胞凋亡,将MCF-7细胞周期阻滞在G1期并引起线粒体功能障碍。此外,促凋亡蛋白caspase-9,caspase-3,Bax和细胞色素c的表达增强,以及抗凋亡蛋白Bcl-2的表达降低,证实了10a诱导了MCF-7细胞内在的凋亡途径。 。强大的抗增殖活性和良好的选择性保证10a是进一步发展为抗癌治疗剂(尤其是乳腺癌)的先导化合物。
