| 产品描述: | 组蛋白甲基转移酶抑制剂;Histone Methyltransferase Inhibitors;;InformationMI-463 MI-463 is a potent inhibitor of Menin-MLL interaction with an IC50 value of 15.3 nM.TargetsMenin-MLL interaction (Cell-free assay) 15.3 nMIn vitroMI-463 demonstrates profound on-target activity in MLL leukemia cells. MI-463 results in substantial growth inhibition, with half-maximal growth inhibitory concentration (GI50) values of 0.23 μM, measured after 7 days of treatment in MLL leukemia cells. MI-463 is effective in inducing differentiation of MLL leukemia cells. Treatment with sub-micromolar concentrations of MI-463 also leads to markedly reduced expression of Hoxa9 and Meis1, downstream targets of MLL fusion proteins substantially upregulated in MLL leukemias.In vivoMI-463 shows substantial survival benefit in mouse models of MLL leukemia. It has very favorable druglike properties, including metabolic stability and PK profile in mice. MI-463 achieves high levels in peripheral blood following a single intravenous or oral dose, while also showing high oral bioavailability(∼45%). In a mouse xenograft model using MV4;11 human MLL leukemia cells implanted into BALB/c nude mice, MI-463 induces strong inhibition of tumor growth with once-daily intraperitoneal (i.p.) administration. It does not impair normal hematopoiesis in vivo.Cell Research(from reference)Cell lines:leukemia cells Incubation Time:6 or 7 days |
| 体内研究: |
MI-463 在单次静脉内或口服剂量后在外周血中达到高水平,同时还显示出高口服生物利用度 (45%)。menin-MLL 相互作用的药理学抑制通过靶向活性显著延迟了小鼠模型中 MLL 白血病的进展而不会引起毒性。每天一次腹膜内 (ip) 给药后,MI-463 会强烈抑制肿瘤生长。MLL 融合蛋白靶基因 HOXA9 和 MEIS1 的表达在用 MI-463 处理后显著降低。用 MI-463 处理 MV4;11 异种移植受体小鼠 20 天也导致白血病进展显著延迟,表现为生物发光水平显著降低,这与外周血中白血病细胞群的显著减少有关,脾脏和骨髓样本。 |
