What is SirReal2?

Description

Sirtuins (SIRTs) represent a distinct class of trichostatin A-insensitive lysyl-deacetylases (class III HDACs). SIRT2 deacetylates histone H4 and α-tubulin and functions as a regulator of cell cycle progression, a determinant of myelination, a modulator of autophagy, and a suppressor of brain inflammation. SirReal2 is an aminothiazole that acts as a SIRT-rearranging ligand to selectively inhibit SIRT2 (IC₅₀ = 140 nM). SirReal2 is >1,000-fold more potent at inhibiting the activity of SIRT2 than that of SIRT1 or SIRT3-6. This compound has been shown to be active in HeLa cells by significantly increasing α-tubulin acetylation.

The Uses of SirReal2

SirReal2 is an aminothiazole that is a potent and selective Sirt2 inhibitor.
