Two series of polymethoxychalcones and polymethoxyflavones, including the natural products 2′-hydroxy-3,4,5,4′,6′-pentamethoxychalcone (8c), 5,6,7,8,3′,4′,5′-heptamethoxyflavone (6), 5,7,3′,4′,5′-pentamethoxyflavone (9c), 3-hydroxy-5,6,7,8,3′,4′,5′-heptamethoxyflavone (7), and 3-hydroxy-5,7,3′,4′,5′-pentamethoxyflavone (10), were synthesized. The antiproliferative activity in vitro was evaluated against a panel of three human cancer cell lines (HeLa, HCC1954, and SK-OV-3) by the cell counting kit-8 (CCK-8) assay. The results showed that most of the synthetic compounds exhibited moderate to potent antiproliferative activities. Some compounds displayed equal or higher potential than the positive control drug cisplatin. In particular, compounds 4c, 4e, 8a, and 9a possess IC50 values equal to or below 10 μM and are worthy of further investigation.
合成了两个系列的五甲氧基
查尔酮和五甲氧基
黄酮类化合物,包括
天然产物2′-羟基-3,4,5,4′,6′-五甲氧基
查尔酮(8c)、5,6,7,8,3′,4′,5′-七甲氧基
黄酮(6)、5,7,3′,4′,5′-五甲氧基
黄酮(9c)、3-羟基-5,6,7,8,3′,4′,5′-七甲氧基
黄酮(7)和3-羟基-5,7,3′,4′,5′-五甲氧基
黄酮(10)。通过细胞计数试剂盒-8(CCK-8)测定法评估了这些化合物对三株人癌
细胞系(HeLa、HCC1954和SK-OV-3)的体外抗增殖活性。结果显示,大多数合成化合物表现出中等到强效的抗增殖活性。一些化合物的潜能与阳性对照药物
顺铂相当或更高。特别是化合物4c、4e、8a和9a的IC50值等于或低于10 μM,值得进一步研究。
