EPZ004777, as a potent epigenetic modulators, can reverse TGF-β1 induced T regulatory cells and may be used to treat diverse immune disorders[1].
In vitro, EPZ004777 has concentration-dependent inhibition of DOT1L enzyme activity with an IC50 of 400 ± 100 pM. In vitro experiment it shown that in MV4-11 cells incubated with 3 μM EPZ004777, a concentration sufficient for maximal cellular DOT1L inhibition. After treatment with 1 day, there is a apparently modest reduction in H3K79me2 levels, but full depletion took 4–5 days. In vitro efficacy test it exhibited that treatment with 3 μM EPZ004777 caused a concentration-dependent decrease of both transcripts in each cell line with IC50 s of approximately 700 nM.[2] In vitro, treatment with 30 μM and 50 μM EPZ004777 obviously decreased cell viability of SW480 cells in a dose-dependent manner. Also 30 μM, 50 μM, and 70 μM EPZ004777 treatment in a dose-dependent manner inhibited the cell viability of HCT116 cells.[3] In vitro, EPZ004777 could also inhibit the proliferation and induce the differentiation of YBT-5 cells[4].
In vivo, nude mice bearing MV4-11 xenograft tumors loaded with a 50 mg/ml solution of EPZ004777, H3K79me2 levels were markedly decreased in tumors from mice treated with EPZ004777 compared to untreated controls.[2] In vivo experiment it demonstated that treatment with 10 and 50?mg/kg EPZ004777 via subconjunctival injection could alleviate corneal injury and opacity.[5].
