WDR5-IN-1 is a potent and selective inhibitor of WD repeat domain 5 (WDR5) (Kd <0.02 nM), and also inhibits MLL1 histone methyltransferase (HMT) activity (IC50: 2.2 nM).
MS67 is a potent and selective degrader of the WD40 repeat domain protein 5 (WDR5) with a dissociation constant (Kd) of 63 nM. It exhibits no activity against protein methyltransferases, kinases, G-protein-coupled receptors (GPCRs), ion channels, and transporters. Notably, MS67 demonstrates significant anticancer properties.
