In this article, we report the findings of a comprehensive structure–activity relationship study of N-(6-ferrocenyl-2-naphthoyl) dipeptide ethyl esters, in which novel analogues were designed, synthesized, and evaluated in vitro for antiproliferative effect. Two new compounds, 2 and 16, showed potent nanomolar activity in the H1299 NSCLC cell line, with exceptional IC50 values of 0.13 and 0.14 μM,
在本文中,我们报告了N-(6-二茂铁基-2-萘甲酰基)二肽乙酯的全面结构-活性关系研究的结果,该研究设计,合成和评估了新的类似物在体外的抗增殖作用。两种新化合物2和16在H1299 NSCLC细胞系中均显示出强大的纳摩尔活性,其出色的IC 50值分别为0.13和0.14μM。还发现这些化合物在Sk-Mel-28恶性黑色素瘤细胞系中具有显着活性(IC 50值分别为1.10和1.06μM)。还进行了研究以阐明这些新型有机金属抗癌化合物的作用方式。H1299细胞系中的细胞周期分析表明,这些化合物可诱导细胞凋亡,而鸟嘌呤氧化研究证实2能够通过ROS介导的机制产生氧化损伤。
