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。
