EN4 is a functional Covalent Ligand Targeting an Intrinsically Disordered Cysteine within MYC. EN4 functionally and covalently targets an intrinsically disordered region in MYC. EN4 directly targets MYC in cells and reduces MYC and MAX thermal stability. EN4 inhibits MYC activity, downregulates MYC targets, and impairs tumorigenesis. MYC is a major oncogenic transcriptional driver of most human cancers that has remained intractable to direct targeting because much of MYC is intrinsically disordered.

How to use

In Vitro:

EN4 directly targets MYC in cells, reduces MYC and MAX thermal stability, inhibits MYC transcriptional activity, downregulates multiple MYC transcriptional targets, and impairs tumorigenesis. EN4 treatment significantly impairs 231MFP breast cancer cell proliferation in a dose- and time-dependent manner. EN4 impairs the cell survival of MYC transformed mammary epithelial MCF10A cells, but not parental MCF10A cells that are not dependent on MYC.

In Vivo:

EN4 treatment initiated after establishment of a 231MFP breast tumor xenograft in immune-deficient mice also significantly attenuates tumor growth in vivo.
