A series of JMJD2A inhibitors had been designed by analyzing the binding mode of 5-carboxy-8-hydroxyquinoline (5-carboxy-8-HQ) with JMJD2A. The inhibitory activity of the synthesized compounds against JMJD2A was determined, followed by docking simulations to understand the structure-activity relationships. Compounds with potent JMJD2A inhibitory activity demonstrated outstanding selectivity for JMJD2A
通过分析5-羧基-8-羟基喹啉(5-羧基-8-HQ)与JMJD2A的结合方式,设计了一系列JMJD2A抑制剂。确定了合成化合物对JMJD2A的抑制活性,然后进行对接模拟以了解结构-活性关系。具有有效JMJD2A抑制活性的化合物对JMJD2A的选择性优于PHD2。选择了几种有效的化合物以评估其对肿瘤细胞系的抗增殖活性。其中,化合物6p表现出最好的抗增殖活性。基于这些体外生物学数据,选择了7种化合物以确定其理化性质。与5-羧基-8-HQ相比,化合物6p显示出良好的水溶性和更好的渗透性。
