Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	SIRT2 ^[1] (Cell-free assay) 140 nM
In vitro	SirReal2 selectively inhibits Sirt2 via a Sirt2-specific amino acid network, and induces a tubulin hyperacetylation and a significant depletion of BubR1 in HeLa cells. ^[1]
In vivo	In vivo, SirReal2 inhibits Sirt2 activity without affecting the activity of the other Class-I sirtuins Sirt1 and Sirt3. ^[1]
