Biological Activity: 

WDR5-C47 is a highly potent and selective antagonist of WDR5-MLL interaction with an IC50 ~0.3 µM. It was designed based on the structure of the WDR5-MLL complex. The WD40-repeat protein WDR5 plays a critical role in maintaining the integrity of the MLL complex and fully activating its methyltransferase function. The MLL complex, the trithorax-like family of SET1 methyltransferase, catalyzes trimethylation of lysine 4 on histone 3, and they have been widely implicated in various cancers. WDR5-C47 could serve as a tool compound to study functions of SET1-family of human histone methyltransferases and further develop therapeutic drug molecules targeting the WDR5−MLL interaction. 


How to Use:


  • In vitro:  WDR5-C47 was suggested to be used at 10 µM final concentration in vitro and in cellular assays.
  • In vivo:  n/a
