fluorescent nucleosides. The synthesis of these extended nucleoside analogues was carried out using Suzuki–Miyaura and Heck alkenylation reactions. A comparison of their photophysical properties allowed the identification of nucleosides 1g and 1h that exhibit the highest quantum yields in an aqueous solution. Studies on the binding interaction of the most promising fluorescent analogues, 1g and 1h, with serum
2'-脱氧尿苷的荧光性质的改善是通过在
尿苷的C–5位直接或通过烯基/苯基/
苯乙烯基连接基引入(杂)芳族基团来创建
生物学上有用的荧光核苷文库而实现的。这些扩展的核苷类似物的合成是使用Suzuki-Miyaura和Heck烯基化反应进行的。通过比较它们的光物理性质,可以鉴定出在
水溶液中具有最高量子产率的核苷1g和1h。最有前途的荧光类似物1g和1h的结合相互作用的研究,与
血清白蛋白蛋白相比,对
α-淀粉酶对
BSA蛋白具有极好的选择性。还进行了对接研究以预测核苷与
BSA的特异性结合位点。
