可以快速有效地访问N-芳基苯并[ b ]呋喃[3,2 - d ]嘧啶-4-胺类库(1)及其新型苯并[ b ]噻吩并[3,2 - d ]嘧啶-4-胺类库首次研究了类似物(2)。通过苯并[ b ]呋喃和苯并[ b ]噻吩前体与N,N的反应获得的N '-(2-氰芳基)-N,N-二甲基甲亚胺通过微波加速缩合和合适的苯胺的Dimroth重排获得标题化合物-二甲基甲酰胺二甲基乙缩醛。这项工作还证明,控制良好的参数可以舒适地使用微波技术,既安全又有益于环境。本文获得的某些产品表现出有趣的体外抗增殖作用。
Synthesis and biological evaluation of N-arylbenzo[b]thieno[3,2-d]pyrimidin-4-amines and their pyrido and pyrazino analogues as Ser/Thr kinase inhibitors
A useful and rapid access to libraries of N-arylbenzo[b]thieno[3,2-d]pyrimidin-4-amines and their pyrido and pyrazino analogues was designed and optimized for the first time via microwave-accelerated condensation and Dimrothrearrangement of the starting anilines with N′-(2-cyanoaryl)-N,N-dimethylformimidamides obtained by reaction of thiophene precursors with dimethylformamide dimethylacetal. The
通过微波加速的缩合反应和Dimroth重排设计并首次优化和优化了N-芳基苯并[ b ]噻吩并[3,2 - d ]嘧啶-4-胺及其吡啶基和吡嗪类似物的库的快速访问方法。通过噻吩前体与二甲基甲酰胺二甲基乙缩醛反应获得的N '-(2-氰基芳基)-N,N-二甲基甲亚胺与起始苯胺。估计了最终产物对五种蛋白激酶(CDK5 / p25,CK1δ/ɛ,GSK3α/β,DYRK1A和CLK1)的抑制力。N-芳基吡啶并[3',2':4,5]噻吩并[3,2 - d ]嘧啶-4-胺系列化合物(事实证明,图4a – j)对于开发新的CK1和CLK1激酶药理抑制剂具有特别的希望。
Microwave-Assisted Synthesis of Potential Bioactive Benzo-, Pyrido- or Pyrazino-thieno[3,2-d]pyrimidin-4-amine Analogs of MPC-6827
microwave-assisted chemical processes were applied to the synthesis of an array of novel N-(4-methoxyphenylamino)-2-methyl benzo-, pyrido- or pyrazino-thieno[3,2-d]pyrimidin-4-amine derivatives. These heteroaromatic systems were envisioned as potent bioisosteric analogues of MPC-6827, an anticancer agent previously developed until phase II clinical studies. A brief evaluation and comparison of their antiproliferative
