realized following application of a versatile and high-yielding scheme, which utilized inexpensive l- and d-arabinose as starting materials, respectively, and which makes use of a regio- and stereo-selective Pummerer rearrangement reaction for the coupling of the nucleobase with the thiosugar moiety. Some of the targeted compounds have shown selective cytotoxic effects (with IC50 <10 μM) against specific
d-和l-系列的新型嘧啶脱氧硫代硫代核苷的合成是通过应用一种通用且高产的方案实现的,该方案分别利用廉价的l-和d-阿拉伯糖作为起始原料,并利用区域和氨基酸。立体选择性Pummerer重排反应,用于将核碱基与硫糖部分偶联。一些目标化合物已显示出 对特定癌细胞系的选择性细胞毒作用(IC 50 <10μM)。所有测试的化合物对测试的正常细胞系均无细胞毒性作用。
