Background | GSK126 is a potent and highly selective inhibitor of EZH2 methyltransferase. |
Biological Activity | GSK126 是一种有效,选择性的 EZH2 甲基转移酶抑制剂,IC50 为 9.9 nM。[1-2] |
In Vitro | GSK126有效地抑制野生型和突变型EZH2甲基转移酶活性,具有相似的效力(Ki = 0.5-3nM),与使用的底物无关,并且与S-腺苷甲硫氨酸(SAM)竞争并且与肽底物不竞争。 GSK126对其他甲基转移酶和多种其他蛋白质类别(EZH1,IC50 = 680 nM)具有高选择性[1]。用GSK126处理三种SCLC细胞系诱导生长抑制。用0.5,2和8μMGSK126处理SCLC细胞系(Lu130,H209和DMS53),并通过WST-8测定分析生长曲线。在所有三种细胞系中,观察到GSK126处理对细胞生长的抑制在8μM,而Lu130和H209对GSK126更敏感,即使在较低剂量下也是如此[2]。 |
In Vivo | 在雌性米色SCID小鼠中以每20g体重0.2mL的剂量体积腹膜内施用GSK126。 GSK126有效抑制EZH2突变体DLBCL细胞系的增殖,并显著抑制EZH2突变体DLBCL异种移植物在小鼠中的生长[1]。 |
Cell Experiment | 将引入JUB和PTRF的DMS53细胞以1×10 3细胞/孔的密度接种在96孔板中,并使用WST-8试剂盒在12,36,60和84小时分析细胞生长。还使用WST-8试剂盒分析了通过DZNep或GSK126处理的Lu130,H209和DMS53的细胞生长。将DZNep以5mM溶解在PBS中,并以5μM的终浓度培养细胞。将GSK126以10mM溶解于DMSO中,并以0.5,2和8μM培养细胞[2]。 |
Animal Experiment | 小鼠[1] GSK126或媒介物以0.2mL / 20g体重的剂量体积腹膜内施用。将100%基质胶中的Pfeiffer或KARPAS-422细胞(1×107)皮下植入雌性米色SCID小鼠中。用卡尺测量肿瘤,并根据肿瘤大小随机分组到治疗组中。对于功效研究,在开始给药之前在每个治疗组中随机化10只小鼠,并且一旦肿瘤体积在Pfeiffer和KARPAS-422研究中为约200mm 3并且在KARPAS-422间歇给药研究中为500mm 3,则开始GSK126治疗。称重小鼠并用卡尺每周两次测量肿瘤。假设两个方差相等的样本进行双尾t检验。 |
Kinase Experiment | 制备含有野生型或突变体(A677G,Y641N,Y641C,Y641H,Y641S或Y641F)EZH2的五元PRC2复合物(Flag-EZH2,EED,SUZ12,AEBP2,RbAp48)。将GSK126溶解在DMSO中,并以0.6nM至300nM的浓度进行测试,最终DMSO浓度为2.5%。与在体外优选H3K27me0作为底物的野生型EZH2相反,EZH2 Y641突变体优选H3K27me2并且对H3K27me0或H3K27me1具有很小的活性。 A677G突变体不同于EZH2的野生型和Y641突变体形式,因为它有效甲基化H3K27me0,H3K27me1和H3K27me2;因此,使用K27me0(野生型,A677G EZH2),K27me1(A677G EZH2)或K27me2(A677G,Y641N,Y641C,Y641H,Y641S和Y641F EZH2)的组蛋白H3肽(残基21-44;最终10μM)作为甲基转移酶底物。将GSK126加入板中,然后加入6nM EZH2复合物和肽。由于GSK126的效力处于或接近[SAM] = Km的测定的紧密结合极限,因此在竞争性底物SAM相对于其Km的高浓度下测量IC 50值(其中SAM Km为7.5μMSAM)0.3μM)[1]。 |
