  • The cells were treated with 1 μM RG2833 (HDAC1/3 inhibitor), 2 μM RGFP966 (HDAC3 inhibitor), 1 μM TSA (pan-HDAC inhibitor), or vehicle for 16 h in serum-free medium. Cell lysates were analysed by Western blotting for expression of SREBP-2 activated fragment, HMG-CoA reductase and APP. Shown are representative blots and quantifications with means ± SEM of the indicated number of independent experiments performed in duplicate. *p < 0.05; **p < 0.01; n.s., not significant in one-sample t-test.

Biological Activity

Description RG2833 (RGFP109) is a brain-penetrant HDAC inhibitor with IC50 of 60 nM and 50 nM for HDAC1 and HDAC3 in cell-free assays, respectively.
Features Orally bioavailable, HDAC inhibitor that penetrates into brain tissue.
HDAC3 [1]
(Cell-free assay)
HDAC1 [1]
(Cell-free assay)
5 nM(Ki) 32 nM(Ki)
In vitro

RGFP109 dose-dependently upregulates frataxin mRNA and protein levels in cultures of unstimulated peripheral blood mononuclear cells (PBMC) obtained from FRDA patients. [1]

In vivo RG2833 (150 mg/kg) corrects frataxin deficiency and increases histone acetylation in the brain and heart of KIKI mice without acute toxicity signs. [1] RGFP109 ameliorates the disease phenotype of a Friedreich ataxia mouse model. [2] RGFP109 (30 mg/kg p.o.) also alleviates established l-DOPA-induced dyskinesia. [3]


Animal Research:

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

  • Mass

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

  • C1

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
