With the aim to create a library of compounds with potential bioactivities by combining special characteristics of two important groups such as nucleobases and carbohydrates, twenty 1,4-disubstituted-triazole nucleosides were synthesized in good yields (80-94%) using the copper catalyzed 'Click' reaction between azido-modified pento- or hexopyranoses and alkyne-bearing pyrimidine or purine nucleobases
为了通过结合两个重要基团(例如核碱基和碳水化合物)的特殊特征来创建具有潜在生物活性的化合物库,使用铜催化的高收率(80-94%)合成了二十个1,4-二取代-三唑核苷。叠氮基修饰的戊或六吡喃糖与带有炔烃的嘧啶或嘌呤核苷碱基之间的“点击”反应。借助光谱技术(例如FTIR,1D-,2D-NMR和ESI-TOFMS)进行结构阐明。使用MTT测定法评估所有合成的三唑核苷对三种人类癌细胞系(MDA-MB-231,Hep3B,PC-3)的细胞毒活性。特别是,化合物3a和1b被鉴定为对Hep3B细胞的潜在打击。
