  Synthesis of Casimiroin and Optimization of Its Quinone Reductase 2 and Aromatase Inhibitory Activities

  摘要：

  An efficient method has been developed to synthesize casimiroin (1), a component of the edible fruit of Casimiroa edulis, on a multigram scale in good overall yield. The route was versatile enough to provide an array of compound 1 analogues that were evaluated as QR2 and aromatase inhibitors. In addition, X-ray crystallography studies of QR2 in complex with compound 1 and one of its more potent analogues has provided insight into the mechanism of action of this new series of QR2 inhibitors. The initial biological investigations suggest that compound 1 and its analogues merit further investigation as potential chemopreventive or chemotherapeutic agents.

  The synthesis of aryl amines via the formation of a C−N bond is an essential tool for the preparation of functional materials, active pharmaceutical ingredients and bioactive products. Usually, this chemical connection is only possible by transition metal-catalyzed reactions, photochemistry or electrochemistry. Here, we report a metal-free arene C−H amination using hydroxylamine derivatives under benign

  通过形成 CN 键合成芳胺是制备功能材料、活性药物成分和生物活性产品的重要工具。通常，这种化学连接只能通过过渡金属催化的反应、光化学或电化学来实现。在这里，我们报告了在良性条件下使用羟胺衍生物进行的无金属芳烃 C-H 胺化。即使在存在各种官能团的情况下，胺化试剂 TsONHR 和芳烃底物之间的电荷转移相互作用也能实现芳烃的化学选择性胺化。氧气对于有效转化至关重要，其对电子转移步骤的加速作用已通过实验证明。此外，

  A novel series of 14 N-nitromethylsulfonanilide derivatives were synthesized and evaluated for their ability to inhibit recombinant aldose reductase. Computational docking simulations provided a good explanation for the observed structure-activity relationships.
