摘要:

锌离子结合基团是组蛋白去乙酰化酶(HDAC)抑制剂结构中的关键部分。本文中设计了一系列含硫的基团, 替换SAHA中的羟肟酸以及BML-210中的苯甲酰胺等经典的锌离子结合基团, 合成了新的HDAC抑制剂。经过对HDAC抑制活性的测试及构效关系分析, 最终发现了一类富含硫的基团(二乙胺基二硫代过硫甲酸酯)是新的有效锌离子结合基团。在所有合成的化合物中, 4d显著优于BML-210, HDAC的亚型1,2的抑制活性与SAHA相当, 被选为先导化合物。

Abstract:

Zinc binding group (ZBG) is the crucial moiety in the chemical structure of any HDAC inhibitor. In the present study, a series of sulphur-containing ZBG were designed and synthesized in the novel HDAC inhibitors to replace the classical ZBGs of SAHA and BML-210,hydroxamic acids and benzamides, respectively. The HDAC inhibitory activity and the structure-activity relationships of these molecules were analyzed. A sulphur-rich group, diethylcarbamo (dithioperoxo)thioate, was finally identifiedas a novel potent ZBG. Among all the synthesized compounds, 4d was much more potent compared with BML-210, and it showed similar inhibitory effect of SAHA against HDAC isoforms 1 and 2. Therefore, it was chosen as a lead compound. 

Key words: Histone deacetylase inhibitor, Zinc binding group, Anticancer
