series of novel indolin-2-ones inhibitors against p90 ribosomal S6 protein kinase 2 (RSK2) were designed and synthesized and their structure–activity relationship (SAR) was studied. The most potent inhibitor, compound 3s, exhibited potent inhibition against RSK2 with an IC50 value of 0.5 μM and presented a satisfactory selectivity against 23 kinases. The interactions of these inhibitors with RSK2 were
设计并合成了一系列新型的针对p90核糖体S6蛋白激酶2(RSK2)的吲哚-2-酮抑制剂,并研究了它们的构效关系(SAR)。最有效的抑制剂化合物3s对RSK2表现出有效的抑制作用,IC 50值为0.5μM,对23种激酶表现出令人满意的选择性。这些抑制剂与RSK2的相互作用是基于拟议的结合姿势和分子对接模拟研究的。四种化合物和六种化合物分别显示出对PC 3细胞和MCF-7细胞适度的抗增殖活性。
