Optimization of a Fragment-Based Screening Hit toward Potent DOT1L Inhibitors Interacting in an Induced Binding Pocket.
Acs Med.Chem.Lett., 7:730-734, 2016

PubMed Abstract: Mixed lineage leukemia (MLL) gene rearrangement induces leukemic transformation by ectopic recruitment of disruptor of telomeric silencing 1-like protein (DOT1L), a lysine histone methyltransferase, leading to local hypermethylation of H3K79 and misexpression of genes (including HoxA), which drive the leukemic phenotype. A weak fragment-based screening hit identified by SPR was cocrystallized with DOT1L and optimized using structure-based ligand optimization to yield compound 8 (IC50 = 14 nM). This series of inhibitors is structurally not related to cofactor SAM and is not interacting within the SAM binding pocket but induces a pocket adjacent to the SAM binding site.
