5%DMSO 40%PEG300 10%Tween80 45%ddH2O
3.6mg/ml Taking the 1 mL working solution as an example, add 50 μL of clarified DMSO stock solution of 72 mg/ml to 400 μL of PEG300, mix evenly to clarify it; add 100 μL of Tween80 to the above system, mix evenly to clarify it; then continue to add 450 μL of ddH2O to make it clear. Volume up to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description RGFP966 is an HDAC3 inhibitor with IC50 of 0.08 μM in cell-free assay, exhibits > 200-fold selectivity over other HDAC.
Targets
HDAC3 [1]
(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. [1] RGFP966 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. RGFP966 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. RGFP966 causes a significant reduction in DNA replication fork velocity within the first hour of drug treatment. [2]
In vivo RGFP966 treatment (10 mg/kg) enhances long-term memory for object memory. RGFP966 (3 or 10 mg/kg, s.c.) facilitates extinction and prevents reinstatement of cocaine- conditioned place preference. [1]

Protocol (from reference)

Kinase Assay:[1]
  • Deacetylation assays

    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.
Cell Assay:[2]
  • Cell lines

    HH and Hut78 CTCL cell lines

  • Concentrations

    ~10μM

  • Incubation Time

    24 to 72 h

  • Method

    Cells are counted and split into T25 (Corning) flasks at 26105 cells/mL. Cells are then treated with DMSO, or HDIs once at hour 0. 100 ml aliquots are taken in triplicate from each flask at 0 hr, 24 hrs, 48 hrs, and 72 hrs after treatment, distributed into a flat bottom 96-well plate, and 10 ml of alamar blue added to each well. After a 4 hr incubation, fluorescence is measured using the Biotek Synergy MX Microplate Reader.
Animal Study:[1]
  • Animal Models

    Mouse

  • Dosages

    10 mg/kg, 10.0 mL/kg

  • Administration

    s.c.
