To utilize the unique scaffold of a natural product indirubin, we herein adopted the strategy of combined pharmacophores to design and synthesize a series of novel indirubin derivatives as dual inhibitors against cyclin-dependent kinase (CDK) and histone deacetylase (HDAC). Among them, the lead compound 8b with remarkable CDK2/4/6 and HDAC6 inhibitory activity of IC50 = 60.9 ± 2.9, 276 ± 22.3, 27.2
为了利用天然产物靛玉红的独特支架,我们在此采用组合药效团的策略来设计和合成一系列新型靛玉红衍生物,作为针对细胞周期蛋白依赖性激酶 (CDK) 和组蛋白脱乙酰酶 (HDAC) 的双重抑制剂。其中,先导化合物8b具有显着的CDK2/4/6和HDAC6抑制活性,IC 50 = 60.9 ± 2.9、276 ± 22.3、27.2 ± 4.2和128.6 ± 0.4 nM,可有效诱导细胞凋亡和S期在几种癌细胞系中停滞。特别是化合物8b可以通过 Mcl-1/XIAP/PARP 轴阻止非小细胞肺癌细胞系 (A549) 的增殖,这与 HDAC 抑制剂和 CDK 抑制剂联合药物的独特作用模式一致。在 A549 静电复印机模型中,化合物8b显示出与其双重抑制相关的显着抗肿瘤功效。我们的数据表明,化合物8b作为单一药物可能是与 CDK 和 HDAC 抑制剂联合用于癌症治疗的有希望的候选药物。
