A nucleosideanalogbased on imidazole-4-acrylamide (urocanamide) was synthesized and studied for its use as a specific ligand for a cytosine–guanosine Watson–Crickbasepair. One- and two-dimensional 1H NMR experiments in methylene chloride at ambient and low temperatures not only indicate the strength of association but also confirm specific binding of the novel nucleoside to the basepair through
合成了基于咪唑-4-丙烯酰胺(尿烷酰胺)的核苷类似物,并研究了其作为胞嘧啶-鸟苷Watson-Crick碱基对的特异性配体的用途。在室温和低温下在二氯甲烷中进行的一维和二维1 H NMR实验不仅表明缔合强度,而且还通过形成两个氢键证实了新型核苷与碱基对的特异性结合。
