CAS No. 931398-72-0
IOX2 (JICL38) is a potent inhibitor of HIF-1α prolyl hydroxylase-2 (PHD2) with IC50 of 21 nM in a cell-free assay, >100-fold selectivity over JMJD2A, JMJD2C, JMJD2E, JMJD3, or the 2OG oxygenase FIH.

NHEK and NHDF are cultivated under normoxic (N) and hypoxic (H) conditions in the presence of IOX2 (50 μM), or vehicle control (DMSO). b HIF-1α levels are analyzed in cell extracts of NHEK (4 h) and NHDF (24 h) by immunoblotting with cellular β-actin as loading control. c Subcellular localization of HIF-1α is examined by immunoblotting analysis of HIF-1α in nuclear (Nu) and cytoplasmic (Cy) fractions with β-tubulin as cytosolic loading control.

|Description||IOX2 (JICL38) is a potent inhibitor of HIF-1α prolyl hydroxylase-2 (PHD2) with IC50 of 21 nM in a cell-free assay, >100-fold selectivity over JMJD2A, JMJD2C, JMJD2E, JMJD3, or the 2OG oxygenase FIH.|
IOX2 potently inhibits PHD2 (IC50 of 21 nM) with over 100-fold selectivity compared to inhibition of JMJD2A, JMJD2C, JMJD2E, JMJD3, or the 2OG oxygenase FIH (IC50s <100 μM). IOX2 is active in cells, inhibiting HIF-1α hydroxylation in RCC4 cells at 50 μM.  Hypoxia Inducible Factor (HIF) is regulated by the hydroxylation of prolyl residues in oxygen-dependent degradation domains in the HIF-1α subunit, which mark it for degradation by the proteosome. 1,2 HIF prolyl hydroxylation is catalyzed by prolyl hydroxylase domain enzymes (PHD1, 2, and 3), members of the Fe(II) and 2-oxoglutarate (2OG) oxygenase family. They require dioxygen as a cosubstrate, thus acting as the hypoxia-sensing component of the HIF system. The activity of PHD is suppressed by hypoxia, increasing both the abundance and activity of the HIF transcriptional complex. 
|In vitro||DMSO||7 mg/mL (19.86 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
5% DMSO+30% 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.

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 SDS / 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 SDS / 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.
