  • Immunoblots showing dose-dependent HIF-1α stabilization in U2OS, HeLa and Hep3b (and HIF-2α) cells after 6 hours treatment with FG-4592.

    Chem Sci, 2017, doi: 10.1039/C7SC02103H. Roxadustat (FG-4592) purchased from Selleck.

    (A) The viability of the EpSCs in each group was detected by CCK-8 assays. The EpSCs were under the indicated conditions for 24 h. The viability of each group is shown as the mean±SD. *, P<0.05 versus the normoxia control group; #, P<0.05 versus the hypoxia control group. (B) Western blotting results showing that FG-4592 simulated hypoxia-induced increases in HIF-1α and PCNA expression.

  • Blood urea nitrogen (A), serum creatinine (B) and serum cystatin C (C) levels. Data were presented as means ± SD (n = 8 in each group). (D) Representative images of periodic acid-Schiff staining (upper: ×100, lower: ×400) of kidneys. (E) Tubular injury score in mice. Data were presented asmeans ± SD of 10 random fields from each kidney (n = 8 in each group).

Biological Activity

Description Roxadustat (FG-4592) is an HIF-α prolyl hydroxylase inhibitor in a cell-free assay, stabilizes HIF-2 and induces EPO production. Phase 3.
HIF α prolyl hydroxylase [1]
(Cell-free assay)
In vitro

FG-4592 is an oral inhibitor of hypoxia inducible factor (HIF) prolyl hydroxylase currently in clinical development for the treatment of anemia. FG-4592 stabilizes the activities of HIF, a cytosolic transcription factor, leading to activation of the genes associated with erythropoiesis, including erythropoietin and enzymes involved in iron metabolism.

Solubility (25°C)

In vitro DMSO 70 mg/mL (198.67 mM)
Water Insoluble
Ethanol Insoluble
In vivo Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
5% DMSO+50% PEG 300+ddH2O
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.

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)

  • Mass
    Molecular Weight

*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).

Dilution Calculator

Dilution Calculator

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 )

  • C1

* 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.
