N-芳基苯并[ b ]噻吩并[3,2 - d ]嘧啶-4-胺及其吡啶和吡嗪类似物作为Ser / Thr激酶抑制剂的合成及生物学评价
摘要:
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。
九种N-(吡啶并[3',2':4,5]噻吩并[3,2 - d ]嘧啶-4-基)am(3)与羟胺盐酸盐的反应产生了新的环化产物。这些是通过嘧啶组分的环裂解,然后形成1,2,4-恶二唑的闭环形成N- [2-([1,2,4]恶二唑-5-基)噻吩并[2,3]而形成的。 [ b ]吡啶-3-基]甲酰胺肟(11)。六个N-(吡啶并[2',3':4,5]呋喃并[3,2 - d ]嘧啶-4-基)idine(12)与盐酸羟胺的反应得到了相似的结果。还评估了新合成的化合物对戊糖苷形成的影响。

We herein report an unprecedented xanthate-based protocol for the preparation of aryl-alkyl thioethers. Heating xanthates with aryl halides and namely cesium carbonate in methanol provides the target thioethers in generally good yields within short reaction times. This method allows one to avoid contact with odorous thiols and also to introduce substituents of which the corresponding thiols are virtually
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
