Flavonoids are polyphenolic compounds which display an array of biological activities and are considered potential antitumor agents. Here we evaluated the antiproliferative activity of selected synthetic flavonoids against human leukemia cell lines. We found that 4′-bromoflavonol (flavonol 3) was the most potent. This compound inhibited proliferation in a concentration-dependent manner, induced apoptosis
类黄酮是多酚化合物,具有多种生物活性,被认为是潜在的抗肿瘤药。在这里,我们评估了选定的合成类黄酮对人类白血病细胞系的抗增殖活性。我们发现4'-溴黄酮醇(黄酮醇3)是最有效的。该化合物以浓度依赖性的方式抑制增殖,诱导细胞凋亡,并在S期阻断细胞周期进程。发现细胞死亡与多种胱天蛋白酶的裂解和激活,丝裂原激活的蛋白激酶途径的激活以及与肿瘤坏死因子相关的两个死亡受体(死亡受体4和死亡受体5)的上调相关。凋亡诱导配体。此外,与单一治疗相比,使用4'-溴黄酮醇和TRAIL的联合治疗导致细胞毒性增加。这些结果为进一步探索该组合在癌症治疗中的潜在应用提供了基础。
