Overexpression of the histone lysine demethylase KDM4A, which regulates H3K9 and H3K36 methylation states, has been related to the pathology of several human cancers. We found that a previously reported hydroxamate-based histone deacetylase (HDAC) inhibitor (SW55) was also able to weakly inhibit this demethylase with an IC50 value of 25.4 μm. Herein we report the synthesis and biochemical evaluations
调节H3K9和H3K36甲基化状态的组蛋白赖氨酸脱甲基酶KDM4A的过表达与几种人类癌症的病理学有关。我们发现以前报道的基于异羟肟酸酯的组蛋白脱乙酰基酶(HDAC)抑制剂(SW55)也能够以25.4μm的IC50值弱抑制这种脱甲基酶。在这里,我们报告了该铅结构的一系列衍生物的合成和生化评估,以及两个正交的体外测定。通过对前导结构进行广泛的化学修饰,还通过利用芳基重氮盐进行自由基芳基化的多功能性,我们能够将衍生物对KDM4A的效力提高至低微摩尔范围,更重要的是,获得了对KDM4A的脱甲基酶选择性。对HDAC的尊重。
