Description

RGFP966 is a selectiveHDAC3inhibitor with anIC50of 80 nM and no effective inhibition of any other HDAC at concentrations up to 15 μM.

IC50& Target

IC50: 80 nM (HDAC3)[1]

In Vitro

RGFP966 potently and selectively inhibits HDAC 3 with IC50of 0.21 μM in RAW 264.7 macrophages, while HDACs 1 (IC50=5.6 μM), 2 (9.7 μM) and 8 (>100 μM), indicating a good level of selectivity for HDAC 3. The mRNA levels of HDACs 1, 2 and 3 are not significantly affected by RGFP966 in RAW 264.7 macrophages, whereas the HDAC 1 and HDAC 2 protein levels are slightly, though significantly, reduced upon RGFP966 treatment. Moreover, RGFP966 significantly reduced the transcriptional activity of NF-κB p65, whereas NF-κB p65 acetylation and localization remain unaltered[2].

In Vivo

RGFP966 (10 and 25 mg/kg) treatment significantly improves body weight, rotarod performance and several measures of motor function in the open field locomoter test[3]. RGFP966 at a 10 mg/kg dose penetrates the blood-brain barrier into rat auditory cortex with typical pharmacokinetics, which together establish feasibility for the modulation of A1 plasticity due to action in the auditory cortex[4].
