compound was obtained through a synthetic sequence of five steps, where all intermediates were fully characterized using spectral data. The analysis of the two tautomers was then evaluated through NMR spectroscopy and theoretical calculations of the chemical shifts and NH coupling constants, which were also compared with the data from guanosine.
DNA中的
鸟嘌呤碱基由于其低氧化电位,因此对
化学修饰特别敏感。由于许多
鸟嘌呤损伤与组织炎症的关系,已经对其进行了详细描述和研究。然而,这些损伤的一个例子是8-硝基
鸟苷的形成,但是仅部分解释了该化合物的NMR数据。通过对该化合物的详细表征,对两种可能的互变异构形式的全面研究对其碱基配对性质具有影响。通过五个步骤的合成序列获得目标化合物,其中使用光谱数据对所有中间体进行了全面表征。
