  colorectal cancer (CRC) that is often associated with dysregulation of Wnt/β-catenin signaling pathway. Herein, we report the discovery of a series of 3,4-dihydrobenzo[f][1,4]oxazepin-5(2H)-one derivatives as a new class of TNIK inhibitors. Structure–activity relationship (SAR) analyses led to the identification of a number of potent TNIK inhibitors with compound 21k being the most active one (IC50:

  Traf2 和 Nck 相互作用蛋白激酶 (TNIK) 是 Wnt/β-catenin 通路的下游信号蛋白，被认为是治疗结直肠癌 (CRC) 的潜在靶点，结直肠癌通常与Wnt/β-连环蛋白信号通路。在此，我们报告发现了一系列 3,4-二氢苯并[ f ][1,4]oxazep​​in-5(2 H )-one 衍生物作为一类新型 TNIK 抑制剂。构效关系 (SAR) 分析鉴定出许多有效的 TNIK 抑制剂，其中化合物21k是最活跃的一种 (IC 50 : 0.026 ± 0.008 μM)。该化合物还对 TNIK 对 406 种其他激酶表现出优异的选择性。在体外试验中，化合物21k可以有效抑制 CRC 细胞增殖和迁移，并在 HCT116 异种移植小鼠模型中表现出相当大的抗肿瘤活性。它还显示出良好的药代动力学特性。总体而言， 21k可能是针对 TNIK 药物发现的有前途的先导化合物，值得进一步研究。

  medicine and materials science, the synthesis of biheteroaryls by cross-coupling remains challenging. We describe here a new, general approach to biheteroaryls: the Ni- and Pd-catalyzed multimetallic cross-Ullmann coupling of heteroaryl halides with triflates. An array of 5-membered, 6-membered, and fused heteroaryl bromides and chlorides, as well as aryl triflates derived from heterocyclic phenols,

  尽管它们对医学和材料科学很重要，但通过交叉偶联合成双杂芳基仍然具有挑战性。我们在这里描述了一种新的、通用的双杂芳基方法：杂芳基卤化物与三氟甲磺酸酯的 Ni 和 Pd 催化的多金属交叉 Ullmann 偶联。一系列 5 元、6 元和稠合杂芳基溴化物和氯化物，以及衍生自杂环酚的芳基三氟甲磺酸酯，被证明是该反应中可行的底物（62 个示例，平均产率为 63 ± 17%）。这种方法对双杂芳基的普遍性在 10 μmol 规模的 96 孔板格式中得到进一步证明。一组 96 种可能的产品在一组条件下提供了 >90% 的命中率。此外，可以使用配体、添加剂和还原剂的单个“工具箱板”快速优化低产率组合。
