4-naphthoquinone derivatives of lawsone (1), 6-hydroxy-1,4-naphthoquinone (2), and juglone (3) were synthesized by alkylation, acylation, and sulfonylation reactions. The yields of lawsone derivatives 1a-1k (type A), 6-hydroxy-1,4-naphthoquinone derivatives 2a-2j (type B), and juglone derivatives 3a-3h (type C) were 52–99%, 53–96%, and 28–95%, respectively. All compounds were tested in vitro for the cytotoxicity
通过烷基化、酰化和磺酰化反应合成了罗松酮 ( 1 )、6-羟基-1,4-萘醌 ( 2 ) 和胡桃酮 ( 3 )的一系列 1,4-萘醌衍生物。罗松酮衍生物1a-1k(A型)、6-羟基-1,4-萘醌衍生物2a-2j(B型)和胡桃酮衍生物3a-3h(C型)的产率为 52-99%、53-96 % 和 28-95%,分别。所有化合物都在体外测试了对人口腔表皮样癌 (KB) 和宫颈上皮样癌 (HeLa) 细胞的细胞毒性,并研究了它们的构效关系。化合物发现3c在 KB 细胞系中最有效(IC 50 = 1.39 µM)。评估了一些化合物对 DNA 拓扑异构酶 I 的抑制作用。化合物2C,3,图3a和图3d显示拓扑异构酶抑制活性与IC 50 8.3-91μM的值。通过循环伏安法检测 pH 7.2 磷酸盐缓冲液中所有萘醌的标准氧化还原电位 (E°)。已发现氧化还原电位与A型化合物的抑制作用之间存在明确的相关性。
