Abstract

Significance: Sirtuin enzymes regulate metabolism and stress responses through deacetylation of specific protein lysine residues. Sirtuins are considered attractive drug targets, but selective inhibitors are rare, and their mechanisms mostly unknown. We report the mechanism of Sirtuin inhibition by Ex-527, a potent Sirt1 inhibitor widely used in physiological studies. A set of Sirtuin/ligand crystal structures, together with activity and binding data, reveals that the compound inhibits by forming a trimeric Sirtuin complex with a NAD + -derived coproduct. Our results yield insights in the unique Sirtuin catalytic mechanism and how it is exploited by Ex-527, and they provide essential information for rational drug development.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
