  MRTX0902 的设计和发现，一种 SOS1:KRAS 蛋白质-蛋白质相互作用的强效、选择性、脑渗透性和口服生物可利用抑制剂

  摘要：

  SOS1 是主要的鸟嘌呤核苷酸交换因子之一，可调节 KRAS 循环通过其“开”和“关”状态的能力。破坏 SOS1:KRAS G12C蛋白质-蛋白质相互作用 (PPI) 可以增加负载 GDP 的 KRAS G12C 的比例，为将 SOS1:KRAS 复合物的抑制剂与靶向 GDP 负载的 KRAS G12C的抑制剂（如 MRTX849）组合提供强有力的机制原理。在本报告中，我们详细介绍了 MRTX0902 的设计和发现——一种有效、选择性、脑渗透性和口服生物可利用的 SOS1 结合剂，可破坏 SOS1:KRAS G12C生产者价格指数。MRTX0902 与 MRTX849 联合口服给药相对于任一单一药物的抗肿瘤活性显着增加，包括 MIA PaCa-2 肿瘤小鼠异种移植模型中一部分动物的肿瘤消退。

• A Pd-catalyzed, boron ester-mediated, reductive cross-coupling of two aryl halides to synthesize tricyclic biaryls
  作者：Zhilong Chen、Xiaodong Wang

  DOI：10.1039/c7ob01237c

  日期：——

  Tricyclic biaryls are important scaffold structures in many natural products and lead compounds in drug discovery. The formation of a biaryl unit is often the key step for the synthesis of tricyclic biaryls. Despite significant progress toward the synthesis of biaryl compounds in recent years, the direct cross-coupling of two different aryl halides is still challenging and robust methods are lacking

  三环联芳基在许多天然产物中是重要的支架结构，在药物发现中是先导化合物。联芳基单元的形成通常是合成三环联芳基的关键步骤。尽管近年来在合成联芳基化合物方面取得了重大进展，但是两种不同的芳基卤化物的直接交叉偶联仍然具有挑战性，并且缺乏可靠的方法。在本文中，我们报道了在钯催化剂和硼酸酯存在下两种不同的芳基卤化物的直接交叉偶联，这为合成三环联芳基提供了一种新的有用的互补方法。

  diversely substituted 2-aroylbenzoate esters featuring a new protocol for the carbonylative coupling of aryl bromides with boronic acids and a new strategy to favour carbonylative over non-carbonylative reactions. Two different synthetic pathways - (i) the alkoxycarbonylation of 2-bromo benzophenones and (ii) the carbonylative Suzuki-Miyaura coupling of 2-bromobenzoate esters - were evaluated. The latter approach
