We report the synthesis of novel 3-substituted (E)-5-(arylidene)-1-methyl-2-thioxoimidazolidin-4-ones 6-11, and their biological evaluation. Based on structural and pharmacophore analyses of known inhibitors such as fluorouracil (5-FU), we envisioned interesting 2-thioxoimidazolidin-4-one compounds, 3-substituted (E)-5-(arylidene)-1-methyl-2-thioxoimidazolidin-4-ones 6-11 that would be expected to
我们报告新的3-取代的(合成ë)-5-(亚芳基)-1-甲基-2-硫代咪唑烷-4-酮6 - 11,以及它们的生物学评价。基于已知抑制剂(例如氟尿嘧啶(5-FU))的结构和药效基团分析,我们设想了有趣的2-thioxoimidazolidin-4-one化合物,3-取代的(E)-5-(亚芳基)-1-甲基-2-thioxoimidazolidin预期与-4 -FU的结构特征完全匹配的-4-ones 6-11。通过5 → 6 → 7 → 10 → 11的合成途径可有效合成二十四种目标化合物6-11,是在考虑了几种可能的合成途径后建立的。通过1-甲基-2-硫代氧杂咪唑啉丁-4-酮(3)的反应合成了一系列(E)-5-(亚芳基)-1-甲基-2-硫代氧杂咪唑啉酮酮5a-d,其依次通过以下步骤制备。的反应ñ甲基甘氨酸(2)用NH 4 SCN,接着Knoevenagel缩合。Ñ烷基化和Ñ -g
