Biological Activity
RGFP966 is a highly selective HDAC3 inhibitor with an IC50 of 80 nM and shows no inhibition to other HDACs at concentrations up to 15 μM.
In Vitro
RGFP966 potently and selectively inhibits HDAC 3 with IC50 of 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].
