N ɛ -acetyl lysine derivatives with zinc binding groups as novel HDAC inhibitors.

HDAC inhibitors have been developed very rapidly in clinical trials and even in approvals for treating several cancers. However, there are few reported HDAC inhibitors designed from N ɛ -acetyl lysine. In the current study, we raised a novel design, which concerns N ɛ -acetyl lysine derivatives containing amide acetyl groups with the hybridization of ZBG groups as novel HDAC inhibitors.
