Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Features	Cell-permeant, broad-spectrum 2OG oxygenase inhibitor.
Targets/IC₅₀/Ki	KDM3A (Cell-free assay) 0.1 μM KDM4C (Cell-free assay) 0.6 μM KDM6B (Cell-free assay) 1.6 μM KDM2A (Cell-free assay) 1.8 μM KDM4E (Cell-free assay) 2.3 μM KDM5C (Cell-free assay) 19 μM PHD2 (Cell-free assay) 33 μM
In vitro	IOX1 increases H3K9me3 levels in HeLa cells via KDM4A inhibition without significant effect on cell viability. This compound shows lower efficacy in HeLa cells due to low cell permeability, while the n-octyl ester derivative improves its cell permeability.
Kinase Assay	AlphaScreen Assay
Kinase Assay	All reagents are diluted in 50 mM HEPES, 0.1% BSA, pH 7.5 supplemented with 0.01% Tween20 and allowed to equilibrate to room temperature prior to addition to plates. Catalytic turnover assays are run in 10 μL volumes in lowvolume 384-well plates at RT. The reaction consisted of enzyme (5 nM), biotinylated substrate peptide (30 nM), Fe(II) (1 μM), ascorbate (100 μM), 2OG (10 μM) and run at RT. For PHD2, the reaction consisted of enzyme (5 nM), biotinylated substrate peptide (60nM), Fe(II) (20 μM), ascorbate (200 μM), 2OG (2 μM) and run at RT. EDTA is used to quench the reaction (5 μL), AlphaScreen donor (Streptavidin-conjugated) and acceptor (Protein A-conjugated) beads preincubated with peptide product antibodies are added (5 μL). Plates are foil-sealed to protect from light, incubated at room temperature for 60 minutes and read on a PHERAstar FS plate reader using an AlphaScreen 680 excitation/570 emission filter set. The final bead concentration in 20 μL reaction is 20 μg/mL. IC50 values are calculated in Prism 6 after normalisation against corresponding DMSO controls.
