Mechanism of Action

Targets/IC₅₀/Ki	HDAC3 (Cell-free assay) 80 nM
In vitro	RGFP966 is a slow-on/slow-off, competitive tight-binding HDAC inhibitor, with an IC50 of 0.08μM for HDAC3 and no effective inhibition of any other HDAC at concentrations up to 15μM. This compound treatment on two CTCL cell lines for 24 hours prior to western blot analysis resulted in increased acetylation at H3K9/K14, H3K27, and H4K5, but not H3K56ac. It decreases cell growth in CTCL (cutaneous T cell lymphoma) cell lines due to increased apoptosis that is associated with DNA damage and impaired S phase progression. This chemical causes a significant reduction in DNA replication fork velocity within the first hour of drug treatment.
Kinase Assay	Deacetylation assays
Kinase Assay	Deacetylation assays are based on the homogenous fluorescence release assay. Purified recombinant enzymes are incubated with serial-diluted inhibitors at the concentrations indicated in the figures, with pre-incubation times ranging from 0 to 3 hours, in the standard HDAC buffer. Acetyl-Lys(Ac)-AMC substrate (at 10 μM, corresponding to the Km for both HDAC1 and HDAC3) is added after the pre-incubation period. The reaction is allowed to run for 1 hour. The trypsin peptidase developer, at final concentration of 5mg/ml, is added after 1 hour, and the fluorescence emission is then measured using a Tecan M200 96-well plate reader.
In vivo	RGFP966 treatment (10 mg/kg) enhances long-term memory for object memory. This compound (3 or 10 mg/kg, s.c.) facilitates extinction and prevents reinstatement of cocaine- conditioned place preference.

Frequently Asked Questions

Question 1:
Does this product S7229 specifically inhibit HDAC3? Or does it target other HDACs as well?

Answer:
In the paper, it is indicated that "this compound is specific for HDAC3, with an IC50 of 0.08 μM and no effective inhibition of any other HDAC at concentrations up to 15 μM." However, we did not perform experiment to confirm this data. Please refer to the following link for detailed information: http://www.pnas.org/content/110/7/2647.long
