Epigenetics regulate the gene expression and chromatin organization associated with the development and occurrence of cancer. Histone deacetylase inhibitors (HDACis) have been proved to be an effective epigenetic targeting drug for cancer treatment. The structures of most HDACis were divided into four parts, including cap group, connection unit, linker region and zinc binding group. We designed a series
表观遗传学调节与癌症的发展和发生相关的基因表达和染色质组织。组蛋白去乙酰化酶抑制剂(HDACis)已被证明是一种有效的用于癌症治疗的表观遗传靶向药物。大多数HDACis的结构分为四个部分,包括帽基、连接单元、接头区和锌结合基团。我们设计了一系列含有苯氧基乙酸酯结构的化合物作为连接区和环己烯作为连接单元的新型抑制剂。代表性化合物YZ1对四种不同的细胞系表现出明显的抗增殖活性,并对 I 类 HDAC 具有强酶抑制活性,IC 50HDAC1-3 分别为 1.6 nM、1.9 nM 和 3.8 nM。此外,YZ1浓度依赖性地抑制 HCT116 细胞的细胞增殖,诱导细胞凋亡和 G2/M 期的周期停滞。通过生物活性评估和对接研究,这些结果表明 YZ1 有可能成为作为 HDAC 抑制剂进一步优化的先导化合物。
