RG2833 is a histone deacetylase (HDAC) inhibitor.
In the neuronal cell, RG2833 increased Friedreich Ataxia (FXN) mRNA and protein levels, with concomitant changes in the epigenetic state of the gene. In PBMCs, RG2833 inhibited HDAC expression and increased H3K9 acetylation, and increased FXN mRNA in blood from patients.
In iPSC-derived neuronal cell model, plasma RG2833 (5μM) inhibited maximal deacetylase and upregulated FXN. The result showed a good correlation between increase in FXN transcript and inhibition of deacetylase activity, providing evidence that the mechanism of action of RG2833 is through deacetylation. [1]

Shipping ConditionEvaluation sample solution: ship with blue ice. All other available sizes: ship with RT, or blue ice upon request.
General tipsFor obtaining a higher solubility, please warm the tube at 37°C and shake it in the ultrasonic bath for a while. Stock solution can be stored below -20°C for several months.


Cell experiment [1]:

Cell lines

Unstimulated peripheral blood mononuclear cells (PBMC) from FRDA Patients.

Preparation method

The solubility of this compound in DMSO is >17mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

1, 2.5, 5 or 10 μM for 48 hours


RG2833 dose-dependently upregulates frataxin mRNA and protein levels in cultures of unstimulated peripheral blood mononuclear cells (PBMC) from FRDA patients.

Animal experiment [2]:

Animal models

GAA knock-in mice

Dosage form

150 mg/kg, subcutaneous injection


RG2833 corrected frataxin deficiency and increases histone acetylation in the brain and heart of KIKI mice (a GAA repeat based FRDA mouse model) without acute toxicity signs.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
