strategy for obtaining new highly functionalized derivatives of emodin (1,3,8-trihydroxy-6-methyl-anthraquinone). Using emodin, DIB, and an appropriate amine as starting materials, we obtained a wide range of emodin-related structures by one-pot synthesis. Several of these derivatives showed stronger cytotoxic and cytostatic activity than emodin. In particular, compound 6 was highly effective on the HepG2
含有蒽醌部分的药物,例如柔红霉素(Daunoblastin)和米托蒽醌(Onkotrone),构成了一些最有效的细胞抑制剂。它们主要通过插入DNA和抑制拓扑异构酶II来抑制肿瘤的生长,并且怀疑会产生导致DNA链断裂的自由基。我们建立了一种新的策略来获得大黄素的新的高度功能化的衍生物(1,3,8-三羟基-6-甲基蒽醌)。使用大黄素,DIB和合适的胺作为起始原料,我们通过一锅法合成获得了大黄素相关的多种结构。这些衍生物中的几种表现出比大黄素更强的细胞毒性和细胞抑制活性。特别地,化合物6对HepG2肿瘤细胞系高度有效,但对正常肝细胞未显示任何细胞毒性。
