产品描述

EPZ-6438是一种有效的和生物可用的EZH2抑制剂,抑制包含EZH2的人PRC2(polycomb repressive complex 2)的活性,Ki值为2.5 nM。EZH2是PRC2(polycomb repressive complex 2)的催化亚单位,催化组蛋白H3赖氨酸27(H3K27)的甲基化。

EPZ-6438竞争结合EZH2的S-腺苷甲硫氨酸(SAM)结合位点,也可以非竞争结合多肽或核小体底物的结合位点。EPZ-6438选择性地抑制EZH2的活性,比对EZH1的选择性高35倍。研究结果表明,在恶性横纹肌样瘤(MRT)模型中,EPZ-6438介导的EZH2的抑制在几个癌症途径中的协同效应使得EPZ-6438具有强烈的和永久性的抗肿瘤活性。
