通过对基于配体的虚拟筛选方法获得的先导化合物的结构优化,设计、合成了一系列苯甲酰肼衍生物,通过1HNMR、13CNMR和MS确定了化合物结构。生物活性测试表明,该系列化合物对RSK2激酶有中等程度的抑制作用。初步揭示了抑制RSK2活性的构效关系,并通过模建的RSK2氮端三维结构揭示了该系列化合物抑制RSK2的作用机制。
A series of benzohydrazide derivatives as novel ribosomal S6 kinase 2 (RSK2) inhibitors were designed and synthesized from a hit compound previously discovered by ligand-based virtual screening. Biological assays showed that these compounds possessed moderate inhibitory activities towards RSK2. The structural activity relationships (SAR) were elucidated by molecular docking and further optimization was performed.
