Further, the electrochemical properties of the representative compounds (7e, 8e and 9e) were evaluated and a definite correlation between the redox potential and the antiproliferative activity. The most potent compound 9e displayed significant anti-leukemic activity with IC50 value of 3.8 μM in HL-60 cells and weak cytotoxicity with IC50 of 40.7 μM in normal cells WI-38. In mechanistic study for 9e
设计,合成和测试带有5,7-二甲氧基部分的1,4-萘醌衍生物作为针对五种人类癌细胞系(A549,Hela,HepG2,NCI-H460和HL-60)的抗肿瘤剂。本文首次描述了所有化合物。构效关系表明2-位氯原子的存在对于抗增殖活性至关重要。此外,评价了代表性化合物(7e,8e和9e)的电化学性质,并且在氧化还原电势和抗增殖活性之间存在明确的相关性。最有效的化合物9e具有IC 50的显着抗白血病活性HL-60细胞的3.8μM值和弱的细胞毒性,正常细胞WI-38的IC 50为40.7μM。在9e的机理研究中,G2 / M期凋亡细胞数量的增加和细胞数量的增加与ROS的产生有关。总之,我们的结果表明2-氯-1,4-萘醌的衍生物可能是治疗早幼粒细胞白血病的有希望的候选者。
