Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

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

Targets/IC50/Ki
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.
