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。
