    Amide-Linked Ribonucleoside Dimers Derived from 5‘-Amino-5‘-deoxy- and 3‘-(Carboxymethyl)-3‘-deoxynucleoside Precursors1
    摘要:
    Treatment of tert-butyldimethylsilyl (TBDMS) derivatives of 3'-keto(adenosine or uridine) with [(ethoxycarbonyl)methylene]triphenylphosphorane gave exocyclic alkenes that underwent stereoselective hydrogenation to give 3'-deoxy-3'-[(ethoxycarbonyl)methyl](Ado or Urd) analogues. Saponification provided the 3'-(carboxymethyl)-3'-deoxy(Ado and Urd) derivatives 37 and 38. Treatment of 37 or 38 with DCC and 5'-amino-2',3'-bis-O-TBDMS-5'-deoxynucleosides gave the amide-linked dimers (74-82%). Activation of 37 or 38 with 4-nitrophenol/DCC, and direct coupling of the 4-nitrophenyl esters with 5'-amino-5'-deoxy(Ado or Urd) in pyridine also produced amide dimers efficiently (65-70%). Analogous activation of a 5'-O-DMT-protected carboxylate, and its coupling with 5'-amino-5'-deoxy-2'-O-methyladenosine gave the amide dimer in good yield (74%). Coupling (DCC) of a 5'-azido-2'-O-TBDMS-3'-(carboxymethyl)-3', 5'-dideoxyuridine intermediate with 5'-amino-5'-deoxynucleosides gave amide-linked dimers (72-78%) that can serve as masked (azide reduction) 5'-amino dimers for analogous synthesis of extended amide-linked oligomers.

    DNA修复酶SNM1A的方酸酰胺和硫代方酰胺抑制剂的合成与评价
    摘要:
    SNM1A 是一种锌依赖性核酸酶,参与从 DNA 中去除链间交联损伤。抑制链间交联修复酶如 SNM1A 是提高交联化疗药物疗效的有前途的策略。最初的研究已经证明了开发 SNM1A 抑制剂的可行性,但这种酶作为药物靶点的全部潜力还有待探索。在此,报道了带有方酸酰胺和硫代方酰胺的核苷衍生物家族的合成及其作为 SNM1A 抑制剂的评价。凝胶电泳分析用于鉴定在 3'-位带有N-羟基方酸酰胺或方酸部分的核苷衍生物,以及带有 5'-硫代方酸酰胺的胸苷衍生物,作为候选 SNM1A 抑制剂。定量IC50测定表明,带有 5'-硫代方酸酰胺的胸苷衍生物是最有效的抑制剂,其次是带有 3'-方酸的胸苷衍生物。进行紫外-可见滴定以评估(硫代)方酸酰胺与锌离子的结合,从而使抑制效力的顺序合理化。研究了活性抑制剂的膜渗透性,其中几种化合物显示出未来体内应用的前景。

    C-branched-chain sugars and nucleosides were obtained by organocatalysis from ulose derivatives. After a reduction step, the corresponding 1,3-diol was derivatized into 3′-spiro-sulfamidates and unexpected sulfates by treatment with a Burgess reagent. Deprotection of the Boc-derivatives was carried out while preserving the cyclic sulfate. An example of ring opening of the cyclic sulfate derivative

    1-(3-C-ethynyl-beta-d-ribo-pentofuranosyl)uracil (EUrd) and its cytosine congener (ECyd) as potential multifunctional antitumor nucleoside antimetabolites. They showed potent and broad-spectrum antitumor activity against various human and mouse tumor cells in vitro and in vivo. To clarify the structure-activity relationship of the sugar moiety, various 3'-C-carbon-substituted analogues, such as 1-propynyl

    Sugar-modified nucleosides are prime synthetic targets in anticancer and antiviral drug development. Radical mediated thiol–ene coupling was applied for the first time on nucleoside enofuranoside derivatives to produce a broad range of thio-substituted D-ribo, -arabino, -xylo and L-lyxo configured pyrimidine nucleosides. In contrast to the analogous reactions of simple sugar exomethylenes, surprisingly

    5'-aldehyde, 3'-ketouridine, and 3'-ketothymidine. The reaction was chemoselective for aldehydes in the presence of nitriles. Acetoxy groups are labile and thus not suitable protecting groups for alcohols under these conditions. N-Benzyl-alpha, N-dilithio methanesulfonamide was found to be of sufficient basicity to cause enolate formation with sensitive substrates, such as 1-phenylacetone. However, the
    本文介绍的是氯化铈(III)介导高产量以及通常非对映选择性地将N-苄基-α,N-二硫代甲磺酰胺加到具有重要生物意义的醛和酮中的能力的第一份报告。对碱敏感的底物,例如Fmoc保护的丙氨酸,柠檬醛,5-胆甾烯-3-酮,尿苷5'-醛,3'-酮胍和3'-酮基吡啶,进行平滑添加。在腈存在下,该反应对醛具有化学选择性。乙酰氧基不稳定,因此在这些条件下不适合作为醇的保护基。发现N-苄基-α,N-二硫代甲烷磺酰胺具有足够的碱性,以引起与敏感底物例如1-苯基丙酮的烯醇化物形成。然而,在这些情况下,氯化铈(III)的加入介导了二价阴离子的碱性并抑制了烯醇化物的形成。另外,铈(III)具有将各种N-脂族/芳族甲磺酰胺二价阴离子加到3'-酮胍中的一般用途。
  • Stereoselective Addition of a Wittig Reagent To Give a Single Nucleoside Oxaphosphetane Diastereoisomer. Synthesis of 2′(and 3′)-Deoxy-2′(and 3′)-methyleneuridine (and cytidine) Derivatives from Uridine Ketonucleosides

    Treatment of 3′,5′(or 2′,5′)-bis-O-silyl-protected 2′(or 3′)-ketouridine derivatives with methyltriphenylphosphonium bromide and sodium 2-methyl-2-butoxide in diethyl ether/benzene at 0-4°C resulted in the slow formation of the corresponding 2′(or 3′)-deoxy-2′(or 3′)-methylene analogues. 1H- and 31P-NMR spectra were in harmony with formation of a single oxaphosphetane diastereoisomer during early stages of the Wittig reaction. Conversions of protected deoxymethyleneuridine to deoxymethylenecytidine derivatives were effected smoothly via 4-(1,2,4-triazol-1-yl) intermediates. Deprotection with tetrabutylammonium fluoride gave 2′(or 3′)-deoxy-2′(or 3′)-methyleneuridine and cytidine nucleosides.
