tazemetostat

Tazemetostat (EPZ6438) 是一种组蛋白甲基转移酶 EZH2 抑制剂 (IC50=11 nM)，具有口服活性、选择性和 SAM 竞争性。Tazemetostat 具有抗肿瘤活性，可以用于治疗上皮样肉瘤 滤泡性淋巴瘤。

Tazemetostat hydrobromide (E-7438 hydrobromide) 是口服的EZH2选择性抑制剂。它抑制含有 PRC2 复合体的野生型 EZH2 的活性，Ki 为 2.5 nM。它还抑制 EZH1，IC50为 392 nM。

Tazemetostat trihydrochloride is a selective and orally available inhibitor of EZH2 (IC50: 4 nM for rat EZH2). It inhibits the activity of human PRC2-containing wild-type EZH2 (Ki: 2.5 nM). It inhibits EZH2 (IC50s: 11 and 16 nM in peptide assay and nucleo

Tazemetostat de(methyl morpholine)-COOH（化合物7）是针对EZH2的PROTAC靶向配体，适用于合成EZH2降解剂（PROTACs）。这些降解剂在治疗弥漫性大B细胞淋巴瘤（DLBCL）及其他淋巴瘤亚型中显示出显著的细胞毒性作用。

Tazemetostat HCl is a potent, selective, and orally bioavailable small-molecule inhibitor of EZH2 enzymatic activity. EPZ-6438 induces apoptosis and differentiation specifically in SMARCB1-deleted MRT cells. Treatment of xenograft-bearing mice with EPZ-6438 leads to dose-dependent regression of MRTs with correlative diminution of intratumoral trimethylation levels of lysine 27 on histone H3, and prevention of tumor regrowth after dosing cessation. These data demonstrate the dependency of SMARCB1 mutant MRTs on EZH2 enzymatic activity and portend the utility of EZH2-targeted drugs for the treatment of these genetically defined cancers.

Tazemetostat de(methylene morpholine)-O-C3-O-C-COOH（Compound 21b）为EZH2降解剂，适用于淋巴瘤研究。
