From Pharmacophore to Warhead: NAD+‐Targeting Triazoles as Mechanism‐Based Sirtuin Inhibitors
We report “Sirtuin Trapping Ligands” (SirTraps), mechanism-based 1,2,3-triazole inhibitors that hijack sirtuin (SIRT) catalysis to form covalent triazolium– or triazole–ADP-ribose (ADPR) adducts from...

In this paper, we demonstrate that the sirtuin SIRT6 can efficiently ADP-ribosylate histidine and tyrosine residues in proteins.

Histidine and tyrosine residues are targets for SIRT6 ADP-ribosylation activity
Abstract. SIRT6, a highly conserved member of the sirtuin family, plays a critical role in diverse cellular processes, including gene regulation, DNA damag

The body of this character is a Jack in the box. Its neck/arms/legs are long and noodle-y. The color scheme is yellow red blue and white. The head of the character is cat-like but also clown like. The background is a grey rectangle over diagonal lines of the color scheme

A bile acid may mimic caloric restriction
The molecule, known to be toxic at higher doses, may activate sirtuin signaling
