Green palladium-catalyzed nitroarene/nitrile reductive cross-annulation chemistry that facilitates straightforward access to pyrrolo[1,2-a]quinoxaline derivatives is described herein. A range of nitriles are activated as carbon synthons to form intramolecular CN and CC bonds using this chemistry. The synthetic protocol has the advantages of broad substrate scope, excellent functional group tolerance
本文描述了绿色钯催化的硝基芳烃/腈还原交叉环化化学,它有助于直接获得吡咯并 [1,2-a] 喹喔啉衍生物。使用这种化学方法,一系列腈被激活为碳合成子,形成分子内 C N 和 C C 键。该合成方案具有广泛的底物范围、优异的官能团耐受性以及使用环保水和廉价的 HCOONa/HCOOH 分别作为溶剂和氢供体的优点。该催化剂可方便地通过过滤回收,至少可以重复使用五次而不会出现明显的失活。这项研究为将散装化学基序转化为增值功能框架提供了一个重要平台。

Embodiments concern methods and small molecule compositions for selectively inhibiting RAD51-mediated D-loop formation while preserving RAD51's ability to form nucleoprotein filaments. The selective RAD51 D-loop formation activity inhibitors DNA repair while minimizing replication-associated toxicity in normal tissue.

target in oncology. Herein we report a novelclass of RAD51 inhibitors that were identified by high throughput screening. In contrast to many previously reported RAD51 inhibitors, our lead compound 1 is capable of blocking RAD51-mediated D-loop formation (IC50 21.3 ± 7.8 μM) at concentrations that do not influence RAD51 binding to ssDNA. In human cells, 1inhibits HR (IC50 13.1 ± 1.6 μM) without blocking
