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.
