Emodin belongs to the anthraquinone class of compounds and is the major bioactive compound of several herb species. A library of novel emodin derivatives was synthesized and their antiproliferative activities were evaluated against HepG2, PC-3, DU-145, MCF-7, and HEK-293 cell lines. Among these derivatives, one showed a higher order of in vitro anticancer activity profile similar to the market drug epirubicin. The derivative strongly inhibited the proliferation of HepG2, PC-3, DU-145 and MCF-7 cancer cell lines with IC50 values of 3.5, 5.6, 7.5, and 4.5 μM respectively. The derivative was also capable of inducing caspase-3-mediated apoptosis in HepG2 cells by arresting the cell cycle in the S phase. Furthermore, the derivative exhibited DNA intercalating ability comparable to doxorubicin, thus making this compound a promising potential antitumor drug.
大黄素属于蒽醌类化合物,是多种草药的主要生物活性化合物。我们合成了一个新型大黄素衍生物库,并评估了它们对 HepG2、PC-3、DU-145、MCF-7 和 HEK-293 细胞系的抗增殖活性。在这些衍生物中,有一种衍生物的体外抗癌活性与市售药物表柔比星相似。该衍生物能强烈抑制 HepG2、PC-3、DU-145 和 MCF-7 癌细胞株的增殖,其 IC50 值分别为 3.5、5.6、7.5 和 4.5 μM。该衍生物还能通过使细胞周期停滞在 S 期来诱导 Caspase-3 介导的 HepG2 细胞凋亡。此外,该衍生物还表现出与多柔比星相当的 DNA 插层能力,因此该化合物有望成为一种潜在的抗肿瘤药物。
