as evidenced by increasing enzymatic conversion rates relative to that of streptonigrin. Hybrids were tested in vitro against a panel of human cell lines including melanoma, breast, and lung cancers. They showed also a high cytotoxic activity depending on the type of 1,4-quinone moiety and the applied tumor cell lines. It was found that cytotoxic activity of the studied hybrids was increasing against
1,4-醌与喹啉的杂化物是通过一个氧原子连接两个活性结构而获得的。该策略允许获得具有高生物活性和合适生物利用度的新化合物。通过各种光谱方法对新合成的化合物进行了表征。所用的酶促测定表明,这些化合物是合适的 DT-心肌黄酶 (NQO1) 底物,这可以通过相对于链黑素增加的酶促转化率来证明。杂交体在体外针对一组人类细胞系进行了测试,包括黑色素瘤、乳腺癌和肺癌。根据 1,4-醌部分的类型和应用的肿瘤细胞系,它们还显示出高细胞毒活性。发现所研究的杂种对具有较高 NQO1 蛋白水平的细胞系的细胞毒活性增加,例如乳腺癌(MCF-7 和 T47D)和肺癌(A549)。测试选择的杂种的转录活性编码增殖标志物(H3 组蛋白)、细胞周期调节剂(p53 和 p21)和细胞凋亡途径(BCL-2 和 BAX)。分子对接用于检查杂种与NQO1蛋白之间可能的相互作用。
