The 2′-substituted-4′-selenoribofuranosyl pyrimidines 3a–3j were synthesized from D-ribose and assayed for anticancer activity. The 2′-azido and 2′-fluoro groups with a ribo configuration were introduced by the regioselective opening of the O2,2′-anhydronucleosides with sodium azide and (HF)x-pyridine, respectively. Among the compounds tested, only 2′-fluoro derivative 3j was found to exhibit significant anticancer activity, but was much less potent than the corresponding 2′-arabino analogue 2c. This study will provide medicinal chemists with the insight into the identification of structural requirements for the anticancer activity for the developments of biologically active nucleosides.
由 D-核糖合成 2'-取代-4'-硒代核糖呋喃糖基嘧啶 3a-3j,并测定其抗癌活性。具有核糖构型的2'-叠氮基和2'-氟基团是通过分别用叠氮化钠和(HF)x-吡啶对O2,2'-脱水核苷进行区域选择性打开而引入的。在测试的化合物中,只有2'-氟衍生物3j被发现表现出显着的抗癌活性,但其效力远低于相应的2'-阿拉伯类似物2c。这项研究将为药物化学家提供深入了解抗癌活性的结构要求的鉴定,以开发生物活性核苷。
