  液相色谱法研究六吡喃糖基化胞嘧啶核苷的降解动力学

  摘要：

  摘要在酸性，中性和碱性pH值和恒定离子强度的缓冲液中，采用液相色谱法跟踪六吡喃糖基化胞嘧啶核苷的降解情况。发现该化合物通过水解成胞嘧啶和/或通过脱氨基成相应的尿嘧啶核苷而降解。酸的降解受糖羟基数量，糖双键的存在和端基异构体类型的影响。将某些化合物的稳定性与相关胸腺嘧啶核苷的稳定性进行了比较。温度研究支持在pH 1.22下水解的单分子机理。

  Synthesis of 2,4-dideoxy-.beta.-D-erythro-hexopyranosyl nucleosides

  摘要：

  The synthesis of 1-(2,4-dideoxy-beta-D-erythro-hexopyranosyl)thymine (12)1 was accomplished using two different synthetic routes. It was obtained starting either from 1,2:5,6-di-O-isopropylidene-alpha-D-glucofuranose or from tri-O-acetyl-D-glucal. The other modified nucleosides, with either a cytosine, guanine, or adenine moiety, were synthesized using the second reaction scheme. Deoxygenation reactions were accomplished with the (2,4-dichlorophenoxy)thiocarbonyl derivatives generated in situ.

  Abstract Liquid chromatography was used to follow the degradation of hexopyranosylated cytosine nucleosides in buffers of acid, neutral and alkaline pH and of constant ionic strength. The compounds were found to degrade by hydrolysis to cytosine and/or by deamination to the corresponding uracil nucleosides. Degradation in acid is influenced by the number of sugar hydroxyl groups, presence of sugar double
