deacetylases (HDAC) inhibitor in combination with janus kinase (JAK) inhibitor could exhibit synergistically anti-proliferative effects in cancer treatment. Herein, we presented a novel series of 2,4-dianilinopyrimidine derivatives, which could simultaneously inhibit JAK2 and HDAC1. Among which, 7l was found to be the most potent compound and displayed balanced inhibitory activity against HDAC1 (IC50 = 1
在单个分子中双重或多重靶向抑制致癌靶点可能是药物组合的替代方法。先前的研究表明,组蛋白去乙酰化酶 (HDAC) 抑制剂与 janus 激酶 (JAK) 抑制剂联合使用可在癌症治疗中发挥协同抗增殖作用。在此,我们提出了一系列新型 2,4-二苯氨基嘧啶衍生物,可同时抑制 JAK2 和 HDAC1。其中,7l被发现是最有效的化合物,并分别显示出对 HDAC1 (IC 50 = 1.9 nM) 和 JAK2 (IC 50 = 0.5 nM) 的平衡抑制活性。7升还对测试的癌细胞系(A549、HepG-2、MDA-MB-231 和 Jurkat)显示出良好的抗增殖活性。此外,流式细胞术分析表明,7l以剂量依赖性方式诱导细胞凋亡和细胞周期停滞,对7l机制的深入了解表明,它可以降低 STAT-3 的磷酸化并促进组蛋白乙酰化。总之,这些结果共同表明7l将是一个有前途的主要候选物,值得进一步研究和开发。
