G9a-like protein and G9a histone lysine methyltransferase (HMTase) inhibitor (IC50 values are 0.7 and 1.7 μM respectively) that displays no activity at other HTMases up to 37 μM. Modulates H3K9me2 levels in mammalian cells and potentiates induction of pluripotent stem cells from somatic cells in vitro.
