WDR5-0103 is a potent and selective WD repeat-containing protein 5 (WDR5) antagonist with Kd of 450 nM. It has no effect on a panel of seven other methyltransferases, including SETD7. It binds in the WDR5 peptide-binding pocket and inhibits the catalytic activity of the MLL core complex in vitro. WDR5-0103 is a good chemical probe to demonstrate inhibition of an important protein-protein interaction and form the basis for further development of inhibitors of WDR5-dependent enzymes implicated in MLL-rearranged leukaemias or other cancers.
