  overexpression. We report the design, synthesis, and structure–activity relationships of 3-(piperidin-4-ylmethoxy)pyridine containing compounds as potent LSD1 inhibitors with Ki values as low as 29 nM. These compounds exhibited high selectivity (>160×) against related monoamine oxidase A and B. Enzyme kinetics and docking studies suggested they are competitive inhibitors against a dimethylated H3K4 substrate

  组蛋白赖氨酸残基的甲基化在基因表达调节以及癌症起始中起重要作用。赖氨酸特异性脱甲基酶1（LSD1）负责维持组蛋白H3赖氨酸4（H3K4）的平衡甲基化水平。由于甲基化的H3K4或LSD1过表达的重要功能，LSD1是某些癌症的药物靶标。我们报告了作为有效LSD1抑制剂的含有3-（哌啶-4-基甲氧基）吡啶的化合物（与K i的设计，合成和结构-活性关系）值低至29 nM。这些化合物对相关的单胺氧化酶A和B表现出高选择性（> 160x）。酶动力学和对接研究表明它们是针对二甲基化H3K4底物的竞争性抑制剂，并提供了可能的结合方式。有效的LSD1抑制剂可以增加细胞H3K4甲基化并强烈抑制EC 50值低至280 nM的几种白血病和实体瘤细胞的增殖，而对正常细胞的作用却微不足道。

  successful synthesis of arylated stibine 3 a in a scale of 34.77 g demonstrates high synthetic potential of this transformation. The formed stibines (R3Sb) were then used for the palladium‐catalyzed carbon–carbon bond forming reaction with aryl boronic acids [R−B(OH)2], giving biaryls with high selectivity, even the structures of two organomoieties (R and R′) are very similar. Plausible catalytic pathways

  镍催化的halostibines交叉偶联，开发了一种形成锑-碳键的策略。该方法已被用于从相应的环状和非环状halostibines合成各种三芳基和二芳基烷基stibines。该方案显示了广泛的底物范围（72个实例），并且与各种官能团（如醛，酮，烯烃，炔烃，卤代芳烃（F，Cl，Br，I）和杂芳烃）兼容。成功合成规模为34.77 g的芳基锑化3a证明了这种转化的高合成潜力。然后将形成的stibines（R 3 Sb）用于与芳基硼酸[ RB （OH）2的钯催化的碳-碳键形成反应，从而产生具有高选择性的联芳基，甚至两个有机基团（R和R'）的结构也非常相似。根据控制实验提出了合理的催化途径。
