  摘要：

  通过合成属于海绵的海洋吡咯-2-氨基咪唑代谢产物的苯并ceptors和oroidin的简化片段，可以实现对Aurora B的显着抑制。激酶抑制作用的评估使得能够发现可合成获得的刚性炔属结构类似物EL-228（1），其结构可以优化为有效的CJ2-150（37）。在这里，我们介绍了新的Aurora B激酶抑制剂的合成，该抑制剂是通过有丝分裂调节进行癌症治疗的重要靶标。生物定向合成产生了几种纳摩尔抑制剂。优化的化合物CJ2-150（37）在Aurora B激酶的混合型抑制中显示了非ATP竞争性变构作用模式。分子对接在变构位点“ F”中确定了可能的结合模式，并强调了与蛋白质的关键相互作用。我们描述了新型支架的抑制力和特异性的提高以及作用机理的表征。

  The super electrophilicity of a shelf-stable, easily prepared trifluoromethylthiolating reagent N-trifluoromethylthio-dibenzenesulfonimide 7 was demonstrated. Consistent with the theoretical prediction, 7 exhibits reactivity remarkably higher than that of other known electrophilic trifluoromethylthiolating reagents. In the absence of any additive, 7 reacted with a wide range of electron-rich arenes
