    Quinoxalinylurea derivatives as a novel class of JSP-1 inhibitors
    摘要:
    A series of quinoxalinylurea-based inhibitors are synthesized and shown to be the novel and potent inhibitors against Jnk Stimulatory Phosphatase-1 (JSP-1), which is a special member of dual-specificity protein phosphatase (DSP) family. Biological assay and computational modeling studies showed the compounds were reversible and noncompetitive inhibitors of JSP-1. JSP-1 inhibitors may be useful for the treatment of inflammatory, vascular, neurodegenerative, metabolic, and oncological diseases in humans associated with dysfunctional Jnk signaling.

  • In water organic synthesis: Introducing itaconic acid as a recyclable acidic promoter for efficient and scalable synthesis of quinoxaline derivatives at room temperature

    日期:2021.4
    Substituted quinoxaline derivatives are traditionally synthesized by co‐condensation of various starting materials. Herein, we describe a novel environmentally benign in water synthetic route for the synthesis of structurally and electronically diverse ninety quinoxalines with readily available substituted o‐phenylenediamine and 1,2‐diketones using cheap and biodegradable itaconic acid as a mild acid
    取代的喹喔啉衍生物传统上是通过各种起始原料的共缩合反应合成的。在本文中,我们描述了一种新型的环境友好的水合成路线,用于合成结构和电子形式多样的90喹喔啉类化合物,并容易获得取代的邻氨基苯甲酸。苯二胺和1,2-二酮在1小时内使用廉价且可生物降解的衣康酸作为温和的酸性促进剂。该反应在室温下进行,该过程通过环缩合反应进行,然后获得上述含氮杂环加合物,而无需进行柱色谱分离,总收率不超过96%。催化剂的简单性,高效率和可重复使用性将该反应条件称为“绿色合成”,这使其可用于克级至克级的合成转化中。
