(SAR) analysis were carried out to the most active hit compound, 9 (IC50: 2.3 μM), which led to the discovery of several new KDM5A inhibitors. Among them, compound 15e is the most potent one with an IC50 value of 0.22 μM against KDM5A. This compound showed good selectivity for KDM5A and considerable ability to suppress the demethylation of H3K4me3 in intact cells. Compound 15e could be taken as a good lead
在此,我们报告发现了一系列新的KDM5A抑制剂。首先基于同源性建模建立了KDM5A jumonji域的三维(3D)结构模型。然后针对商业化学数据库进行基于分子对接的虚拟筛选。检索了许多命中化合物。对活性最高的化合物9(IC 50:2.3μM )进行了进一步的结构优化和结构-活性关系(SAR)分析,从而发现了几种新的KDM5A抑制剂。其中,化合物15e是最强效的IC 50相对于KDM5A的0.22μM值。该化合物显示出对KDM5A的良好选择性,并具有在完整细胞中抑制H3K4me3脱甲基化的显着能力。化合物15e可作为进一步研究的良好先导化合物。
