摘要:

异戊烯基黄酮类化合物主要分布在豆科和桑科植物中, 具有多种生物活性。我们之前报道了一个从甘草中得到的异戊烯基异黄酮isoangustone A (IAA)可以通过破坏线粒体功能诱导结肠癌细胞凋亡。本文比较了来自甘草的其它一些结构相近的黄酮类化合物和IAA的抗增殖活性和对胞内信号通路的影响, 发现AB环上的异戊烯基对其活性有重要贡献, 而邻位酚羟基和C环共轭平面也有一定影响。此外, 这些异戊烯基黄酮类化合物可以导致PARP-1切割、AMPKACC磷酸化增加、mTOR4EBP1磷酸化降低, 并激活自噬信号。基于以上的初步构效关系研究, 我们还从甘草中发现了另外4个异戊烯基黄酮类化合物也具有较强的抗肿瘤活性。本研究初步建立了异戊烯基黄酮类化合物的构效关系, 研究了它们对胞内信号的影响, 并从甘草中发现了一些值得进一步研究的先导化合物。

Abstract:

Prenylated flavonoids are mainly distributed in Leguminosae and Moraceae plants, and they have been reported to possess various biological activities. Previously, we have reported a prenylated isoflavonoid, isoangustone A (IAA) from licorice (Glycyrrhiza uralensis), which induces apoptosis in colorectal cancer cells by disrupting mitochondrial functions. In the present study, we compared a group of flavonoids from licorice with IAA for their anti-proliferation activities and effects on intracellular signaling. The results indicated that the isoprenyl groups on the A and B rings, the hydroxyl groups at the ortho position of isoprenyl on A ring and the conjugated plane of C ring might contribute to the anti-cancer activity of prenylated flavonoids. Based on the above structure-activity relationship, we further identified four prenylated flavonoids with similar anti-cancer activities from licorice. Taken together, our present study established a preliminary structure-activity relationship of anti-cancer prenylated flavonoids, and our data provided important leading compounds from licorice, which deserved further research and development.
