previously shown antitumor activity. In this study we present the synthesis, chemical characterization and in vitro anti-proliferative activity of three [(η6-p-cymene)Ru(L)Cl] neutral complexes, where L = hispolon derivatives. The single crystal X-ray structures of the three Ru complexes all have the expected piano stool geometry with the p-cymene ligand at the apex of the piano stool and occupying three of
Hispolon 是从桑黄和桑黄真菌中提取的天然产物,此前已显示出抗肿瘤活性。在这项研究中,我们介绍了三种 [(η 6 - p -伞花烃)Ru(L)Cl] 中性配合物的合成、化学表征和体外抗增殖活性,其中 L = hispolon 衍生物。三种Ru配合物的单晶X射线结构都具有预期的钢琴凳几何形状,p-聚伞花烃配体位于钢琴凳的顶点,并以扭曲的八面体排列占据三个位置。完成八面体配位球的是去质子化hispolon衍生物的两个β-二酮氧原子,它们以双齿方式配位 和一个氯原子。研究了三种 hispolon 衍生物及其相应复合物对 A549 肺、HCT116 结肠和 U87 胶质母细胞瘤细胞系的细胞毒性。在胶质母细胞瘤细胞系中,生物活性增加(降低 IC 50) 在芳烃-钌络合后对所有三种 hispolon 均可见:2,3,4-三甲氧基-hisp8 (Hisp8) 高 5.1 倍,3-甲氧基,4-羟基-hisp1
