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
