Dot1L-IN-2 is a potent, selective and orally bioavailable inhibitor of Dot1L (a histone methyltransferase), with an IC50 and Ki of 0.4 nM and 0.08 nM, respectively.

Dot1L-IN-2 is a potent, selective Dot1L inhibitor, with an IC50 and Ki of 0.4 nM and 0.08 nM, respectively. Dot1L-IN-2 potently inhibits H3K79 dimethylation (IC50, 16 nM), and blocks the activity of the HoxA9 promoter (IC50, 340 nM) in cellular systems. Dot1L-IN-2 also dramatically suppresses proliferation of the human MLL-rearranged leukemia cell line MV4-11 carrying the oncogenic MLL-AF4 fusion (IC50, 128 nM)[1].
