A series of flavonoids 9a–f, 13b, 13d, 13e and 14a–f bearing diverse aliphatic amino moieties were designed, synthesized and evaluated for their cytotoxic activities against the ECA-109, A-549, HL-60, and PC-3 cancer cell lines. Most of the compounds exhibited moderate to good activities. The structure-activity relationships were studied, revealing that the chalcone skeleton is the most preferable for cytotoxic activities. Chalcone 9d was the most promising compound due to its high potency against the examined cancer cell lines (its IC50 values against ECA-109, A549, HL-60 and PC-3 cells were 1.0, 1.5, 0.96 and 3.9 μM, respectively).
一系列具有多样脂肪族氨基结构片段的黄酮类化合物9a–f、13b、13d、13e以及14a–f被设计、合成并评估了它们对人食管癌ECA-109、肺癌A-549、早幼粒白血病HL-60以及前列腺癌PC-3细胞株的细胞毒活性。多数化合物表现出了中等到良好的活性。通过构效关系研究,揭示了查耳酮骨架是最有利于细胞毒活性的。查耳酮9d是最有潜力的化合物,因其对上述癌细胞株展现出高强度的抑制作用(其对ECA-109、A549、HL-60及PC-3细胞株的IC50值分别为1.0、1.5、0.96和3.9 μM)。
