Clear solution
5%DMSO 30%PEG300 65%ddH2O
2.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 40 mg/ml clarified DMSO stock solution to 300 μL of PEG 300, mix evenly to clarify it; then continue to add 650 μL of ddH2O to adjust the volume 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 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.
Targets
PHD2 [1]
(Cell-free assay)
21 nM
In vitro 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. [1] 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. [2]
