  EED结合结构抑制变构抑制表观遗传多梳抑制复合物2（PRC2）甲基转移酶的设计。

  摘要：

  PRC2是一种多亚基甲基转移酶，参与早期胚胎发育和细胞生长的表观遗传调控。催化亚基EZH2主要使组蛋白H3的赖氨酸27甲基化，从而导致染色质紧实和肿瘤抑制基因的抑制。通过靶向EZH2的小分子抑制该活性可显示出抗肿瘤功效。在这里，我们描述了代表一类新的PRC2抑制剂的化学系列的优化，该类PRC2抑制剂通过非催化EED亚基的三甲基赖氨酸口袋发生变构作用。解构较大且复杂的筛选物会产生简单的片段大小的分子，然后进行结构引导的再生长和仔细的性质调节，以产生在功能测定和细胞活性中实现亚微摩尔抑制的化合物。

  simple methodology for the reduction of acid chlorides to their corresponding alcohols has been developed. Various carboxylic acids were converted to alcohols in excellent yields using NaBH4-K2CO3 in a mixed solvent system of dichloromethane and water (1:1) in the presence of a phase-transfer catalyst at low temperature. The importance of the work is its simplicity, selectivity, excellent yield, and very
