|Description||Chidamide is a low nanomolar inhibitor of HDAC1, 2, 3, and 10, the HDAC isotypes well documented to be associated with the malignant phenotype with IC50 values of 95, 160, 67, 78 nM for HDAC1, 2, 3, 10 respectively.|
Chidamide inhibits class I HDACs 1-3, as well as class IIb HDAC10, at low nanomolar concentrations. Chidamide significantly induces histone H3 acetylation in both HeLa human cervical adenocarcinoma cells and human PBMC. Cell growth inhibition studies performed with 18 human-derived tumor cell lines demonstrate that chidamide and MS-275 similarly inhibit the in vitro growth of most, but not all, tumor cells in the low micromolar concentration range. However, chidamide, and to a lesser extent MS-275, is significantly less toxic to normal cells from human fetal kidney (CCC-HEK) and liver (CCC-HEL), indicating a differential cytotoxic response of normal cells versus cancerous cells to chidamide.
|In vivo||In HCT-8 colorectal carcinoma mice xenografts, Chidamide shows in vivo antitumor activity. Chidamide in the dose range of 12.5-50 mg/kg dose-dependently reduces tumor size and tumor weight, and the dose of 50 mg/kg produces similar or greater efficacy compared with the control drugs 5-fluorouracil(5-FU, 20 mg/kg) and MS-275 (25 mg/kg, which was reported as the maximum tolerated dose in xenograft models). However, chidamide is well-tolerated at the above doses in the tumor-bearing animals, whereas the control drugs cause significant weight loss.|
|In vitro||DMSO||78 mg/mL (199.78 mM)|
|Ethanol||2 mg/mL (5.12 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
1% CMC Na
For best results, use promptly after mixing.
* 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.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
