Identification of a cell-active non-peptide sirtuin inhibitor containing N-thioacetyl lysine

Bioorg Med Chem Lett. 2009 Oct 1;19(19):5670-2. doi: 10.1016/j.bmcl.2009.08.028. Epub 2009 Aug 12.

Abstract

To identify cell-active sirtuin inhibitors containing N-thioacetyl lysine, we synthesized compound 1, which was designed based on the structure of the reported N-ethoxycarbonylacetyl lysine-based sirtuin inhibitor NCS-12k. Compound 1 selectively inhibited SIRT1 in enzyme assays. Compound 1 also caused a dose-dependent increase in p53 acetylation in human colon cancer HCT116 cells, indicating the inhibition of SIRT1 in these cells.
