产品描述
EPZ-5676是蛋白甲基转移酶 DOT1L的S-腺苷甲硫氨酸(SAM) 竞争性抑制剂,Ki为80 pM,比作用于所有其他PMTs选择性高37,000以上,抑制肿瘤H3K79甲基化。
靶点
DOT11L
         
IC50
80 pM Ki
         
体外研究
EPZ-5676 reduces H3K79 dimethylation with a cellular IC50 of 2.6 nM in MV4-11 cells. EPZ-5676 treatment results in concentration- and time-dependent reduction of H3K79 methylation without effect on the methylation status of other histone sites, which leads to inhibition of key MLL target genes and selective, apoptotic cell killing in MLL-rearranged leukemia cells. EPZ-5676 inhibits proliferation of MLL-AF4 rearranged cell line MV4-11 with an IC50 of 9 nM.
体内研究
EPZ-5676 continuously intravenous infusion for 21 days to xenograft model of MLL-rearranged leukemia, leads to dose-dependent anti-tumor activity. At the highest dose of 70.5 mg/kg/day, complete tumor regressions are achieved with no regrowth for up to 32 days after the cessation of treatment. No significant weight loss or obvious toxicity is observed in rats treated with EPZ-5676 during efficacy study.
溶解性
DMSO 100 mg/mL,水 <1 mg/mL,乙醇 100 mg/mL
稳定性
2年 -20°C粉状,6月-80°C溶于DMSO
