Mechanism of Action

Targets/IC₅₀/Ki	Wdr5-MLL interaction WDR5 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).
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.
