Résumé Biologically active organic molecules acting as nucleoside mimics are frequently encountered in pharmaceutical research. They are either synthetic heterocycles, which miss the sugar-derived interactions with the active site of the nucleoside-binding protein, or natural products containing a glycosidic linkage, which may cause bioavailability and metabolic stability problems. We report here the concept of synthetic full nucleoside mimics, including both a N-containing nucleobase-like portion and a sugar-like moiety, where the latter consists of 5- and 6-membered carbacycles connected by a more stable and drug-like CN bond to the nucleobase mimic. Compounds 14, 16 (indolinones), 21 and 23 (benzimidazolones) have been prepared as model compounds.

摘要 作为核苷模拟物的
生物活性有机分子在药物研究中经常遇到。它们要么是合成的杂环,无法与核苷结合蛋白的活性位点发生糖源性相互作用;要么是含有糖苷键的
天然产物,可能会导致
生物利用度和代谢稳定性问题。我们在此报告合成全核苷模拟物的概念,其中包括一个含 N 的类
核糖基部分和一个类糖分子,后者由 5 元和 6 元
碳环组成,通过更稳定和类似药物的 CN 键与类
核糖基模拟物连接。已制备出化合物 14、16(
吲哚啉酮类)、21 和 23(
苯并咪唑酮类)作为模型化合物。 补充材料: 本文的补充材料以单独文件形式提供:mmc1.pdf
