产品描述

GSK126是EZH2的抑制剂,Ki值为93 pM [1]。

据报道,EZH2的过表达与多种癌症类型中癌症的发展和预后不良相关。GSK126是一种有效的EZH2抑制剂,其对EZH2/PRC2活化形式的作用时间比对非活化形式更长 [1]。在淋巴瘤细胞系中,EZH2突变(比如Y641N、Y641F或A677G)具有更高的敏感性 [2]。在DMS53、LU30和H209小细胞肺癌细胞(SCLC)中,分别用0.5、2和8 μM的GSK126处理细胞后均抑制了细胞生长 [3]。在卵巢癌细胞中,GSK126也可以显著恢复ARNTL的表达,从而抑制细胞生长,提高对cisplatin的敏感性 [4]。

在KARPAS-422皮下异种移植模型中,GSK126间断给药可以有效抑制肿瘤生长。在EZH2突变的DLBCL肿瘤异种移植小鼠模型中,GSK126也可以娴熟抑制肿瘤生长 [2]。
