Solubility (25°C)* In vitro DMSO 100 mg/mL (179.98 mM)
Ethanol 8 mg/mL (14.39 mM)
Water Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5% DMSO 95% Corn oil
0.8mg/ml Taking the 1 mL working solution as an example, add 50 μL of 16 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
5.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 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 OICR-9429 is a potent antagonist of the interaction of WDR5 with peptide regions of MLL and Histone 3 and reduces viability of acute myeloid leukemia cells in vitro. It binds to WDR5 with high affinity (KD = 93 ± 28 nM.
Targets
Wdr5-MLL interaction [1] WDR5 [1]
93 nM(Kd)
In vitro

OICR-9429 binds WDR5 with high affinity (Kd=93±28 nM) and competitively disrupts its interaction with a high-affinity Wdr5-interacting (WIN) peptide of MLL (Kdisp=64±4 nM)[1].
In vivo

OICR-9429, a potent WDR5 inhibitor, suppressed proliferation, metastasis and PD-L1-based immune evasion while enhancing apoptosis and chemosensitivity to cisplatin in bladder cancer by blocking the WDR5-MLL complex mediating H3K4me3 in target genes.

Protocol (from reference)

Cell Assay:

[1]
  • Cell lines

    Primary human AML cells

  • Concentrations

    5 μM
