RG2833 (RGFP109) is a potent and selective brain-penetrant HDAC inhibitor with IC50 of 60 nM and 50 nM for HDAC1 and HDAC3, respectively. It upregulates frataxin mRNA and protein levels dose-dependently in cultures of unstimulated peripheral blood mononuclear cells (PBMC) obtained from FRDA patients. In vivo it corrects frataxin deficiency and increases histone acetylation in the brain and heart of KIKI mice without acute toxicity signs.

How to use

In Vitro:

RG2833 was used at 10 µM final concentration in vitro and cellular assays.

In Vivo:

RG2833 (RGFP109) could be dosed to KIKI mice by subcutaneous injection at 150 mg/kg, correct frataxin deficiency and increases histone acetylation in the brain and heart of KIKI mice without acute toxicity signs. RG2833 could be orally dosed to mice at 30 mg/kg, alleviate established l-DOPA-induced dyskinesia.
