of molecules in the search for bioactive compounds. In our continuing efforts to develop novel nucleoside analogs, we used the Sonogashira cross-coupling reaction to synthesize 1,2,4-triazole acyclonucleosides bearing various arylethynyl groups on the triazole nucleobase. By employing 3-iodotriazole nucleoside as the coupling substrate, the Sonogashira reaction proceeded efficiently even with alkynes
在寻找生物活性化合物中,核苷衍生物是一类重要的分子。在我们不断努力开发新的核苷类似物的过程中,我们使用了Sonogashira交叉偶联反应来合成在三唑核碱基上带有各种芳基乙炔基的1,2,4-三唑无环核苷。通过使用3-碘三唑核苷作为偶联底物,Sonogashira反应即使在炔烃中也有效地进行,炔烃是众所周知的无反应性和挑战性的试剂。进一步的晶体结构分析揭示了3-芳基乙炔基三唑基序的共面特征,表明它们作为大型平面芳族系统或核碱基的替代物的潜力。最重要的是,几种合成的化合物对各种癌细胞均表现出令人感兴趣的抗增殖活性,并诱导了细胞凋亡,
