Abstract

Previously, we designed and synthesized a series of bis-substituted aromatic amide-based histone deacetylase (HDAC) inhibitors. In this study, we report the replacement of a bromine atom by different amides on the phenyl ring of the CAP region. Representative compounds and exhibited low nanomolar IC values against HDAC1, which were ten times lower than that of the positive control SAHA. The IC of against the human A549 cancer cell line was 2.13 μM. Furthermore, increased the acetylation of histones H3 and H4 in a dose-dependent manner. Moreover, significantly arrested A549 cells at the G2/M phase and induced A549 cell apoptosis. Finally, molecular docking investigation rationalized the high potency of compound .

摘要

此前,我们设计并合成了一系列基于双取代芳族酰胺的组蛋白脱乙酰酶(HDAC)抑制剂。在本研究中,我们报道了在CAP区域的苯环上用不同的酰胺取代溴原子。代表性化合物 和 对HDAC1表现出低纳摩尔IC值,比阳性对照SAHA低十倍。 对人A549癌细胞系的IC为2.13 μM。此外, 以剂量依赖性方式增加组蛋白H3和H4的乙酰化。此外, 显著将A549细胞阻滞在G2/M期并诱导A549细胞凋亡。最后,分子对接研究解释了化合物 的高效力。
