  Antitrypanosomal Activity of 5‘-Deoxy-5‘-(iodomethylene)adenosine and Related 6-N-Cyclopropyladenosine Analogues

  摘要：

  Treatment of the 6-N-cyclopropyl-2',3'-di-O-isopropylideneadenosine 5'-aldehyde with sulfone-stabilized phosphonate or fluorophosphonate reagents followed by stannyldesulfonylations and subsequent iodo- or protiodestannylation gave 6-N-cyclopropyl-5'-deoxy-5'-(iodomethylene)adenosine 8b or its 5'-fluoromethylene analogue 11. Treatment of the 5'-aldehyde with hydroxylamine or dibromomethylene- or cyanomethylene-stabilized Wittig reagents and deprotections gave the oxime 4b, 5'-cyanomethylene 5b, and 5'-dibromomethylene 13b analogues. Dehydrobromination of 13b gave acetylenic compound 14b. From the tested 6-N-cyclopropyladenosine analogues modified at the 5' carbon, the 5'-iodomethylene 8b had the most potent activity against Trypanosoma brucei in vitro with an IC50 of 12 mu g/mL. The IC50 value was 19 mu g/mL for both the 5'-fluoromethylene 11 and the 5'-cyanomethylene 5b compounds. The (E)-5'-deoxy-5'-(iodomethylene)adenosine 2a, a known inhibitor of AdoHey hydrolase not modified with a cyclopropyl ring at 6-amino group, also inhibited T. brucei with an IC50 of 9 mu g/mL. In contrast to some other adenosine analogues modified at C5', the 6-N-cyclopropyladenosine analogues described here do not exhibit an inhibitory effect on AdoHcy hydrolase and displayed only marginal antiviral activity.

  组蛋白甲基转移酶DOT1L含腺苷抑制剂的合成及构效关系研究

  摘要：

  组蛋白 3-赖氨酸 79 (H3K79) 甲基转移酶 DOT1L 已被发现是具有 MLL（混合谱系白血病）基因易位的急性白血病的药物靶点。总共设计和合成了 55 种含腺苷的化合物，其中鉴定了几种有效的 DOT1L 抑制剂，K i值低至 0.5 nM。与其他三种组蛋白甲基转移酶相比，这些化合物还显示出高选择性（> 4500 倍）。讨论了这些化合物对 DOT1L 的抑制活性的构效关系 (SAR)。强效 DOT1L 抑制剂对 MLL 易位白血病细胞系 MV4;11 和 THP1 的增殖具有选择性活性，EC 504–11 μM 的值。等温滴定量热研究表明，两种代表性抑制剂以高亲和力与 DOT1L:核小体复合物结合，仅与酶辅因子 SAM（S-腺苷-1-甲硫氨酸）竞争，而不与底物核小体竞争。

  methylation of Npl3p, a known in vivo Rmt1 substrate, could be moderately reduced by N(6)-naphthylmethyl-SAH in the resulting allele. In addition, an N(6)-benzyl-SAM analogue was found to serve as an orthogonal SAM cofactor. This analogue is preferentially utilized by the mutant methyltransferase relative to the wild-type enzyme with a selectivity greater than 67. This specific enzyme/inhibitor and enzyme/substrate

  蛋白质精氨酸甲基转移酶催化甲基从 S-腺苷甲硫氨酸 (SAM) 转移到靶蛋白中的精氨酸侧链，调节转录、RNA 加工和受体介导的信号传导。为了专门解决该家族各个成员的功能作用，我们采用了“凹凸洞”的方法，并设计了一系列针对酵母蛋白的 N(6)-取代的 S-腺苷高半胱氨酸 (SAH) 类似物甲基转移酶 RMT1。在 Rmt1 中发现了一个点突变 (E117G)，这使得该酶容易受到 SAH 类似物的选择性抑制。基于质谱的酶分析表明，N(6)-苄基-和 N(6)-萘甲基-SAH 两种化合物可以抑制突变酶，选择性大于 20。当 E117G 突变被引入酿酒酵母染色体时，Npl3p（一种已知的体内 Rmt1 底物）的甲基化可以通过 N(6)-萘基甲基-SAH 在所得等位基因中适度降低。此外，发现 N(6)-苄基-SAM 类似物可作为正交 SAM 辅因子。相对于选择性大于 67 的野生型酶，这种类似物优先

  5'-O-[N-(salicyl)sulfamoyl]adenosine (Sal-AMS) is a prototype for a new class of antitubercular agents that inhibit the aryl acid adenylating enzyme (AAAE) known as MbtA involved in biosynthesis of the mycobactins. Herein, we report the structure-based design, synthesis, biochemical, and biological evaluation of a comprehensive and systematic series of analogues, exploring the structure-activity relationship

  N6-methyladenosine(m6A) is the most abundant modification in mRNA. Studies on proteins that introduce and bind m6A require the efficient synthesis of oligonucleotides containing m6A. We report an improved five-step synthesis of the m6A phosphoramidite starting from inosine, utilising a 1-H-benzotriazol-1-yloxytris(dimethylamino)phosphoniumhexafluorophosphate (BOP)-mediated SNAr reaction in the key

  N6-甲基腺苷 (m6A) 是 mRNA 中最丰富的修饰。对引入和结合 m6A 的蛋白质的研究需要有效合成含有 m6A 的寡核苷酸。我们报告了从肌苷开始的 m6A 亚磷酰胺的改进的五步合成，在关键步骤中利用 1-H-苯并三唑-1-基氧基三（二甲氨基）鏻六氟磷酸盐（BOP）介导的 SNAr 反应。与报道的路线相比，该路线的总产量显着增加，并且可用于合成其他腺苷衍生物的亚磷酰胺，例如乙醇腺苷，一种由重要的抗癌药物卡莫司汀形成的 DNA 加合物的 RNA 类似物。
• <i>N</i>-Cycloalkyl Derivatives of Adenosine and 1-Deazaadenosine as Agonists and Partial Agonists of the A₁ Adenosine Receptor

  A number of cycloalkyl substituents (from C-3 to C-8) have been int-reduced on the 6-amino group of adenosine, 1-deazaadenosine, and 2'-deoxyadenosine, bearing or not a chlorine atom at the 2-position, to evaluate the influence on the A(1) and A(2A) affinity of steric hindrance and lipophilicity. Furthermore, the guanosine 5'-triphosphate (GTP) shift and the maximal induction of guanosine 5'-(gamma-thio)triphosphate ([S-35]GTP gamma S) binding to G proteins in rat brain membranes were used to determine the intrinsic activity of these nucleosides at the A(1) adenosine receptor. All compounds of the ribose-bearing series proved to be full agonists, the 1-deaza derivatives showing affinities for the Al receptor about 10-fold lower than the corresponding adenosines. On the other hand, all the 2'-deoxyribose derivatives bind to the A(1) receptor with affinities in the high nanomolar range, with the 2-chloro substituted compounds showing slightly higher affinities than the 2-unsubstituted counterparts. In terms of the potencies, the most potent compounds proved to be those bearing four- and five-membered rings. Both GTP shifts and [S-35]-GTP gamma S experiments showed that most of the 2'-deoxyadenosine derivatives are partial agonists, The 2'-deoxyadenosine derivatives which were identified as partial agonists consistently detected fewer Az receptors in the high-affinity state than full agonists. However, it is worthwhile noting that there was not a simple Linear relationship between receptor occupancy and activation. These results indicate that a critical density of A(1) adenosine receptors in the high-affinity state is required for G protein activation.
