discovery. In this study, a series of acylhydroquinones with different acyl-chain length, and their chlorinated derivatives, in the aromatic ring, synthesized by Fries rearrangement under microwave irradiation, were evaluated for their anticancer activity in two leukemia cell lines. Findings from the primary and secondary screening of the 18 acylhydroquinones, tested at 5 µM on acute promyelocytic
由于癌细胞与非癌细胞相比具有不同的线粒体生物能量需求,因此其线粒体功能的治疗性抑制仍然是发现抗癌药物的重要目标。在这项研究中,评估了一系列具有不同酰基链长度的酰基氢醌及其在芳香族环中的氯化衍生物,它们是在微波照射下通过Fries重排合成的,在两种白血病细胞系中具有抗癌活性。通过对18份酰基氢醌的初次和二次筛选的结果(在急性早幼粒细胞白血病HL-60和急性淋巴细胞白血病CEM细胞系上以5 µM的测试进行检测),发现了酰基氯氢醌(12)对HL-60细胞具有高度选择性的抗增殖作用。该化合物在HL-60细胞的细胞周期进程中诱导S期停滞,对白血病CEM细胞和非癌性Hs27细胞无明显毒性。在HL-60白血病细胞中,有12种触发线粒体NADH氧化增加,在寡霉素(状态4o)下呼吸增加,线粒体去极化和ROS产生,表明OXPHOS的解偶联。这激发了依赖于AMPK / ACC /自噬轴的代谢适应,由于12和依托
