SirReal2
Based on 2 publication(s) in Google Scholar
SirReal2 is a potent, isotype-selective Sirt2 inhibitor with an IC50 value of 140 nM and has very little effect on the activities of Sirt3-5. SirReal2 leads to tubulin hyperacetylation in HeLa cells and induces destabilization of the checkpoint protein BubR1. SirReal2 combined with VS-5584 (HY-16585) suppresses tumor growth and extends the survival rate of mice in tumor xenograft model. SirReal2 is is promising for research of cancer, inflammation and neurodegeneration.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (4.95 mM); Clear solution
