A series of 3-substituted uridine and pseudouridine derivatives, based on the naturally occurring 3-(3-amino-3-carboxypropyl) modification, were synthesized. Their aqueous solution conformations were determined by using circular dichroism and NMR spectroscopy. Functional group composition and chain length were shown to have only a subtle influence on the distribution of syn/anti conformations of the
合成了一系列基于天然存在的 3-(3-amino-3-carboxypropyl) 修饰的 3-取代尿苷和假尿苷衍生物。它们的水溶液构象是通过使用圆二色性和核磁共振光谱确定的。显示官能团组成和链长对修饰的核苷的顺/反构象的分布只有细微的影响。决定核苷构象的主要因素似乎是糖苷键(C-与N-糖苷)。
