Eleven new 2-O-side-chain derivatives of alizarin were synthesized via esterification, substitution, hydrolysis, or elimination reactions. The structures of all the products were confirmed by 1H NMR, MS, and elemental analysis. Compared with alizarin, most of the derivatives had significantly higher DNA binding affinity based on interaction with ct-DNA. In particular, compound 8 exhibited the best cytotoxicity against HeLa cells with IC50 20 μM and could induce HeLa cells apoptosis.
合成了十一种新的铝紫色素2-O侧链衍生物,采用了酯化、取代、水解或消除反应。所有产物的结构都通过1H NMR、质谱和元素分析进行了确认。与铝紫色素相比,大多数衍生物的DNA结合亲和力显著提高,基于与ct-DNA的相互作用。特别是化合物8对HeLa细胞表现出最佳的细胞毒性,其IC50为20 μM,并能够诱导HeLa细胞凋亡。
