DOT1L Inhibitor, SYC-522

A cell permeable S-adenosyl-L-methionine (SAM) derivative that acts as a highly potent and selective inhibitor of histone 3-lysine79 (H3K79) methyltransferase DOT1L (K_i = 500 pM ) and inhibits H3K79 methylation. Does not affect the activity of PRMT1, CARM1 and SUV39H1 (IC₅₀ >100 µM). Blocks cell cycle at the G0/G1 phase. Although it does not induce apoptosis, it sensitizes MLL rearranged leukemia cells to chemotherapeutic agents (mitoxantrone, etoposide, cytarabine) to cause apoptotic cell death. Shown to down-regulate the expression of HOXA9 and MEIS1, leukemia-relevant genes, by over 50%.

Please note that the molecular weight for this compound is batch-specific due to variable water content.
