Chemical structure of HDAC inhibitors. Thailandepsin A (TDP-A), thailandepsin B (TDP-B) and FK228 are depsipeptides characterized by a bicyclic structure containing a signature disulfide bond; the prodrugs can be activated by cellular reduction, indicated by a star sign (*). SAHA is a hydroxamic acid marked by a pound sign (#)
