Biological Activity:

SirReal2 is a potent and selective Sirt2 inhibitor with IC50  ~140 nM, has minimal effect on Sirt1 and Sirt3-6. It occupies the extended C-site and induces a major rearrangement of Sirt2’s active site, so it selectively inhibits Sirt2 and functions as a molecular wedge to lock Sirt2 in an open conformation. SirReal2 can increase tubulin hyperacetylation in HeLa cells and induces destabilization of the checkpoint protein BubR1. It could be a useful chemical tool for sirtuin biology.

How to use: 

In vitro: SirReal2 was used at 10-20 μ M final concentration in vitro and in cellular assays.
In vivo: n/a
