  Synthesis and biological evaluation of 2′-substituted-4′-selenoribofuranosyl pyrimidines as antitumor agents

  摘要：

  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。

  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 first synthesis of 4′-selenothymidine (1), a novel DNA building block, and 4′-seleno-AZT (2) was accomplished from 2-deoxy-d-ribose via stereoselective formation of 2-deoxy-4-seleno-d-furanose 17 and a Pummerer-type base condensation as key steps. 4′-Selenothymidine (1) was discovered to adopt the same 2′-endo/3′-exo conformation as thymidine, which is unusual in that 4′-selenouridine has the opposite

  4'- selenothymidine（第一合成1），一个新的DNA构建块，和4'-硒代AZT（2）由2-脱氧-完成d -核糖经由立体选择性形成2-脱氧-4-硒的d-呋喃糖17和Pummerer型碱的缩合反应是关键步骤。发现4'-硒代嘧啶（1）具有与胸苷相同的2'-endo / 3'-exo构象，这是不寻常的，因为4'-硒代尿苷具有与尿苷相反的构象。

  The first synthesis of oligonucleotides containing 4'-selenium-modified ribonucleotides (4'-Se-rN) is described. Four sequences containing 4'-Se-rT were successfully synthesized and compared with DNA and RNA oligonucleotides containing a dT, rT, or LNA insert in place of the 4'-Se-rT. The 4'-Se-rT behaved more like rT than dT in its effects on binding affinity, despite the DNA-like structure previously

  描述了含有 4'-硒修饰核糖核苷酸 (4'-Se-rN) 的寡核苷酸的首次合成。成功合成了四个含有 4'-Se-rT 的序列，并与含有 dT、rT 或 LNA 插入物代替 4'-Se-rT 的 DNA 和 RNA 寡核苷酸进行了比较。4'-Se-rT 对结合亲和力的影响比 dT 更像 rT，尽管之前观察到核苷的 DNA 样结构，表明在掺入寡核苷酸后会发生构象转换。将 4'-Se-rT 掺入 A-RNA 和杂交双链体导致结合亲和力增加，而掺入 B-DNA 使双链体在与 rT 核苷酸相同的程度上不稳定。

  Stereoselective synthesis of novel 2',3'-didehydro-2',3'dideoxy-4'-selenonnucleosides (4'-seleno-d4Ns) 4a-c was accomplished via 4'-selenoribofuranosyl pyrimidines 11a-c, as key intermediates. 4'-Selenoribofuranosyl pyrimidines 11a-c were efficiently synthesized from D-ribose or D-gulonic gamma-lactone using a Pummerer-type condensation as a key step. Introduction of 2',3'-double bond was achieved by treating cyclic 2',3'-thiocarbonate with 1,3-dimethyl-2-phenyl-1,3,2-diazaphospholidine.

  The syntheses of four selenonucleosides, namely 4 '-O-selenoadenosine, -cytidine, -thymidine, and -uridine are described. Commercially available D-ribonolactone was converted to the key intermediate 1,4-anhydro-4-seleno-D-ribitol in seven steps in overall excellent yield. Oxidation of the seleno-D-ribitol with MCPBA gave a single diastereomeric selenoxide in excellent yield, which upon Pummerer reaction in the presence of silylated purine or pyrimidine bases gave stereoselectively the corresponding 4'-beta-selenonucleosides. The stereochemistry at the anomeric center was determined by means of 1D-NOE experiments. (C) 2008 Elsevier Ltd. All rights reserved.
