  Structure–activity relationships of 2′-modified-4′-selenoarabinofuranosyl-pyrimidines as anticancer agents

  摘要：

  Based on the potent anticancer activity of the D-arabino-configured cytosine nucleoside ara-C, novel 2'-substituted-4'-selenoarabinofuranosyl pyrimidines 3a-3u, comprising azido, fluoro, and hydroxyl substituents at C-2' were designed, synthesized, and evaluated for anticancer activity. The 2'-azido group was stereoselectively introduced by the Mitsunobu reaction using diphenylphosphoryl azide (DPPA), and the 2'-fluoro group was stereoselectively introduced through the double inversions of stereochemistry via the episelenium intermediate, which was formed by the participation of the selenium atom. Among the compounds tested, the 2'-fluoro derivative 3t (X = NH2, Y = H, R = F) was found to be the most potent anticancer agent and showed more potent anticancer activity than the control, ara-C in all tested human cancer cell lines (HCT116, A549, SNU638, T47D, and PC-3) except the leukemia cell lines (K562). The anticancer activity of the 2'-substituted-4'-selenonucleosides is in the following order: 2'-F > 2'-OH > 2'-N3.

  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。
