The polycomb repressive complex 2 (PRC2) is composed of three core subunits, enhancer of zeste 2 (EZH2), embryonic ectoderm development (EED), and suppressor of zeste 12 (SUZ12), along with a number of accessory proteins. It is the key enzymatic protein complex that catalyzes histone H3 lysine 27 (H3K27) methylation to mediate epigenetic silencing of target genes. PRC2 thus plays essential roles in maintaining embryonic stem cell identity and in controlling cellular differentiation. Studies in the past decade have reported frequent overexpression or mutation of PRC2 in various cancers including prostate cancer and lymphoma. Aberrant PRC2 function has been extensively studied and proven to contribute to a large number of abnormal cellular processes, including those that lead to uncontrolled proliferation and tumorigenesis. Significant efforts have recently been made to develop small molecules targeting PRC2 function for potential use as anticancer therapeutics. In this review, we describe recent approaches to identify and develop small molecules that target PRC2. These various strategies include the inhibition of the function of individual PRC2 core proteins, the disruption of PRC2 complex formation, and the degradation of its subunits.

针对癌症中的多梳抑制复合物2(PRC2)的小分子方法。
聚梳抑制复合物2(PRC2)由三个核心亚基,zeste 2增强子(EZH2),胚外胚层发育(EED)和zeste 12抑制子(SUZ12)以及许多辅助蛋白组成。它是催化组蛋白H3赖氨酸27(H3K27)甲基化以介导靶基因表观遗传沉默的关键酶蛋白复合物。因此,PRC2在维持胚胎干细胞身份和控制细胞分化中起着至关重要的作用。过去十年的研究报告说,PRC2在多种癌症(包括前列腺癌和淋巴瘤)中经常过度表达或突变。异常的PRC2功能已被广泛研究,并被证明可导致大量异常细胞过程,包括那些导致不受控制的增殖和肿瘤发生的过程。最近已经做出重大努力来开发靶向PRC2功能的小分子,以潜在地用作抗癌治疗剂。在这篇综述中,我们描述了识别和开发靶向PRC2的小分子的最新方法。这些各种策略包括抑制单个PRC2核心蛋白的功能,破坏PRC2复合物的形成以及其亚基的降解。
