Although it has been known for its role as a fusion protein in mixed lineage leukemia (MLL), overexpression of native ENL, and thus dysregulation of downstream genes in acute myeloid leukemia (AML), has recently been implicated as a driver of disease that is reliant on the epigenetic reader activity of the YEATS domain. We developed a peptide displacement assay (histone 3 tail with acylated lysine) and screened a small-molecule library totaling more than 24,000 compounds for their propensity to disrupt the YEATS domain¨Chistone peptide binding. Among these, we identified a first-in-class dual inhibitor of ENL (Kd = 745 ˇŔ 45 nM) and its paralog AF9 (Kd = 523 ˇŔ 53 nM) and performed ˇ°SAR by catalogˇ± with the aim of starting the development of a chemical probe for ENL %K YEATS domain %K MLLT1 %K ENL %K MLLT3 %K AF9 %K small-molecule inhibitor %U https://journals.sagepub.com/doi/full/10.1177/2472555218809904
