Seventeen new flavone derivatives substituted at the 4′-OH position were designed, synthesized and evaluated for their anticancer and antibacterial activities. Among them, compounds 3, 4, 6f, 6e, 6b, 6c and 6k demonstrated the most potent antiproliferative activities against a human erythroleukemia cell line (HEL) and a prostate cancer cell line (PC3). The results also showed that the IC50 value of compounds 3, 4, 6f, 6e, 6b, 6c and 6k were close to that of the anticancer drug cisplatin (DDP) and lower than that of apigenin. All of the derivatives did not present antibacterial activities. The structure–activity relationships evaluation showed that the configuration of methyl amino acid might affect their biological activities.
设计、合成并评估了在4'-OH位置取代的十七种新黄酮衍生物的抗癌和抗菌活性。其中,化合物3、4、6f、6e、6b、6c和6k表现出对人类红细胞白血病细胞系(HEL)和前列腺癌细胞系(PC3)具有最强的抗增殖活性。结果还显示,化合物3、4、6f、6e、6b、6c和6k的IC50值接近于抗癌药顺铂(DDP)的值,低于芹菜素。所有衍生物均未表现出抗菌活性。结构活性关系评估表明,甲基氨基酸的构型可能影响它们的生物活性。
