Description: WDR5-0103 is a small molecule that binds a peptide-binding pocket on WDR5 (Kd = 450 nM), inhibiting the catalytic activity of the MLL core complex in vitro (IC50 = 39 µM). WD repeat domain 5 (WDR5) plays an important role in various biological functions through the epigenetic regulation of gene transcription. WDR5 may have oncogenic effect and WDR5-mediated H3K4 methylation plays an important role in leukemogenesis.
