WDR5-0103 is a potent and selective 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). WDR5-0103 antagonizes the interaction of WDR5 with MLL by competing with MLL for their mutual binding site on WDR5. WD repeat domain 5 (WDR5) plays an important role in various biological functions through the epigenetic regulation of gene transcription.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
