名稱 | Pinometostat |
描述 | Pinometostat (EPZ-5676) is a potent DOT1L histone methyltransferase inhibitor (Ki=80 pM). Pinometostat has antitumor activity and can be used in experiments to study a variety of leukemia treatments. |
細(xì)胞實(shí)驗(yàn) | EPZ-5676 is dissolved in DMSO. To analyse inhibition of histone methylation in MV4-11 cells following EPZ-5676 treatment, extracted histones (400 ng) are fractionated on a 10-20% Tris HCl gels with Tris-Glycine SDS running buffer under denaturing conditions and transferred to nitrocellulose filters. Filters are cut into strips and incubated for 1 hour in blocking buffer at room temperature (RT) and then incubated overnight at 4°C in blocking buffer. Filters are washed 3 times for 5 minutes with wash buffer (Phosphate buffered saline (PBS) including 0.01% Tween 20 (PBST)) and incubated with infrared tagged secondary antibody at RT for 1 hour. Filters are washed in PBST and reprobed for 1 hour at RT with the appropriate total histone antibody control (mouse anti-histone H3 (1:20,000), CST 3638, or mouse anti-histone H4 (1:10,000), CST 2935). Filters are washed again in PBST and incubated with infrared tagged secondary antibody (IRDye 800Cw donkey-anti-mouse IgG (1:20,000), Li-Cor 926-32212) at RT for 1 hour. After a final ish in PBST, filters are scanned using the Odyssey infared imager (Li-cor). To analyse inhibition of H3K79 methylation in peripheral blood mononuclear cells (PBMCs) from rats dosed with EPZ-5676, 20 μL of PBMC whole cell lysate is fractionated on denaturing gels and analysed by immunoblotting with antibodies to H3K79me2 or total H3. Signal intensities specific for the H3K79me2 antibody and total histone H3 control antibody are quantified using Odyssey software. The H3K79me2 signal intensity is normalized by dividing it by the total histone H3 control signal intensity in the same lane. |
體外活性 | 方法: MLL-r 和 non-MLL-r AML 細(xì)胞用 Pinometostat (0.1-10 μM) 處理 4-16 天,通過 flow cytometry 檢測細(xì)胞增殖。 結(jié)果: 攜帶 MLL-AF4 或 MLL-AF9 融合物的 MV4-11、MOLM-13 和 NOMO-1 細(xì)胞系在治療 8 天后細(xì)胞數(shù)量急劇減少,IC50 值低于 1 μM。相比之下,均缺乏 MLL-r 的 U-937 或 HL-60 細(xì)胞的增殖不受 Pinometostat 的影響。令人驚訝的是,DOT1L 抑制對MLL-AF9 陽性 THP-1 細(xì)胞沒有影響,而它顯著降低了非 MLL-r OCI-AML3 細(xì)胞系的增殖。[1] 方法: 人白血病細(xì)胞 MV4-11 用 Pinometostat (0.06-1000 nM) 處理 4 天,通過 Western Blot 檢測靶點(diǎn)蛋白表達(dá)水平。 結(jié)果: 在 Pinometostat 濃度增加的情況下,表達(dá) MLL-AF4 的 MV4-11 的整體細(xì)胞甲基化 H3K79 水平的濃度依賴性降低。[2] |
體內(nèi)活性 | 方法: 為檢測體內(nèi)抗腫瘤活性,將 JSH-23 (50 mg/kg,2% DMSO+30%PEG 300+5% Tween80+63% PBS) 腹腔注射給攜帶 MDA-MB-468 腫瘤的 NSG 小鼠,每兩天一次,給藥 6 次。 結(jié)果: Pinometostat 在 10 周內(nèi)顯著降低了腫瘤體積和原發(fā)性腫瘤的轉(zhuǎn)移。[3] |
