indole at room temperature, while heating the reaction mixture at 50 °C provided an unexpected 2-halo-3-arylthio indole with construction of C–S and C–S/C–X (X = Cl and Br) bonds without addition of any external halogenating agent via cascade sulfenylation–halogenation reactions under metal-oxidant-base-free conditions. Further, insight into the reaction mechanism provides an unprecedented observation

compound bound to the CREB binding protein (CBP) and the first bromodomain of BRD4 (BRD4(1)) were used to guide the design of more selective compounds. The crystal structures obtained revealed two distinct binding modes. By varying the aryl substitution pattern and developing conformationally constrained analogues, selectivity for CBP over BRD4(1) was increased. The optimized compound is highly potent (Kd
缺乏针对溴结构域和末端外 (BET) 亚家族之外的溴结构域的小分子抑制剂。在这里,我们描述了人类赖氨酸乙酰转移酶 CBP/p300 溴结构域模块的高效和选择性配体,由一系列 5-异恶唑基苯并咪唑开发而成。我们的出发点是片段命中,使用 Suzuki 偶联、苯并咪唑形成反应和还原胺化的平行合成将其优化为更有效和选择性更强的先导化合物。使用热稳定性测定法研究了先导化合物对其他溴结构域家族成员的选择性,结果显示对结构相关的 BET 家族成员有一些抑制作用。为了解决 BET 选择性问题,与 CREB 结合蛋白 (CBP) 和 BRD4 的第一个溴结构域 (BRD4(1)) 结合的先导化合物的 X 射线晶体结构用于指导更具选择性的化合物的设计。获得的晶体结构揭示了两种不同的结合模式。通过改变芳基取代模式和开发构象受限的类似物,增加了 CBP 超过 BRD4(1) 的选择性。优化后的化合物具有高效 (Kd

The selective C3-sulfonylation of some 4-, 5- and 6-substituted indoles using sodium arenesulfinates as reaction partners has been realised under mild conditions using catalytic CuI/1,10-phenanthroline at 70 °C. The reaction had a satisfactory application scope and proceeded in fair to excellent yields.
