Target Point | EZH2 |
Passage | Epigenetics |
Background | Tazemetostat is a potent, selective EZH2 inhibitor. |
Biological Activity | Tazemetostat (EPZ-6438) 是一种有效,选择性,口服的 EZH2 抑制剂,Ki 和 IC50 分别为2.5和11 nM。[1-3] |
IC50 | Ki: 2.5nM(EZH2)[1] |
In Vitro | Tazemetostat(EPZ-6438)以与底物S-腺苷甲硫氨酸(SAM)竞争的方式抑制EZH2。 Tazemetostat抑制EZH1,EZH2(在肽测定中),EZH2(在核小体测定中),IC50分别为392nM,11nM和16nM。与其他14种测试的HMT相比,Tazemetostat的选择性相对于EZH1为35倍,选择性> 4,500倍[1]。 |
In Vivo | Tazemetostat(EPZ-6438,125mg / kg)在给药期间诱导肿瘤停滞,并且与给药期后的载体相比产生显著的肿瘤生长延迟。在第21天给药前5分钟或给药后3小时测量Tazemetostat血浆水平显示全身暴露的明显剂量依赖性增加[1]。通过ELISA测量,在给予Tazemetostat(EPZ-6438,口服给药,100,300或1,000mg / kg)的大鼠的PBMC和骨髓中观察到剂量依赖性靶抑制[2]。 |
Cell Experiment | 293T(CRL-11268),RD(CRL-136),SJCRH30(CRL-2061),A204(HTB-82),G401(CRL-1441),G402(CRL-1440),KYM-1(JCRB0627),293T使用RD,SJCRH30,A204,G401和G402细胞。在第0天,细胞未经处理,经DMSO处理,或者以10μM开始用Tazemetostat处理,并以三倍或四倍稀释度降低。使用Cell Titer Glo在第0天,第4天和第7天读取平板,在第4天补充化合物/培养基。在第7天,将六孔板用胰蛋白酶消化,离心并重新悬浮在新鲜培养基中用于计数。 VI-细胞。将来自每种处理的细胞以96孔板中的原始密度重复一式三份。使细胞粘附于平板过夜,并在第0天处理细胞。在第7,11和14天,使用Cell Titer Glo读取平板,在第11天补充化合物/培养基。一式三份的平均值为用于绘制时间过程中的增殖,并计算IC50值。对于细胞周期和细胞凋亡,将G401和RD细胞以每板1×10 6个细胞的密度一式两份接种在15-cm培养皿中。将细胞与Tazemetostat以1μM一起孵育,总共25mL,历时14天,细胞在第4,7和11天分裂回原始接种密度。细胞周期分析和TUNEL测定使用番石榴流式细胞仪[1]。 |
Animal Experiment | 携带sc G401异种移植物的小鼠[1] SCID小鼠在右侧腹侧用G401肿瘤细胞(每只小鼠5×10 6个细胞)皮下接种于0.2-mL基础培养基和基质胶的混合物中用于肿瘤发展。对于肿瘤功效研究,肿瘤大小达到157mm 3时开始治疗(每组n = 16只小鼠)。 Tazemetostat(125mg / kg,250mg / kg和500mg / kg)或媒介物(0.5%NaCMC加0.1%吐温80水溶液)以10μL/ g的剂量体积口服BID 21或28 d。在第一周期间每天测量动物体重,然后在研究的剩余部分每周测量两次。使用卡尺在两个维度上每周测量肿瘤大小两次,并且体积以立方毫米表示。大鼠[2]雄性和雌性Sprague-Dawley大鼠(8周龄)用Tazemetostat(100,300或1,000mg / kg)或载体口服治疗28天,每天一次。在第22天,来自最高剂量组的雌性接受另一剂量,随后在最后一次给药后约29小时在第23天安乐死。在第28天最后一次给药后约29小时,在第29天对所有其他动物实施安乐死。在安乐死时,收集全血量,分离外周血单核细胞(PBMC),并将细胞沉淀冷冻并储存在-80℃。 |
