Description
InformationIOX2 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.In vitroIOX2 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 vivoCell Datacell lines：Concentrations：Incubation Time：Powder Purity:≥99%
