report the design, synthesis, and evaluation of an S-adenosylmethionine-based focused chemical library which led to the discovery of potent small-molecule inhibitors directly targeting the MLL SET domain. Determination of cocrystal structures for a number of these MLL inhibitors reveals that they adopt a unique binding mode that locks the MLL SET domain in an open, inactive conformation.
