  • A tetrazine templated method for the synthesis of ternary conjugates
    作者:Boddu Venkateswara Rao、Snehal Dhokale、Pattuparambil R. Rajamohanan、Srinivas Hotha

    Conjugation is an important reaction that enables coupling of molecules. Many protocols exist for the synthesis of binary conjugates from two different molecules or for the polyvalent display of a single molecule. There aren't many methods for the synthesis of ternary conjugates. However, methods for ternary conjugation are important for understanding the interplay of interactions between three biomolecules (or any three molecules per se). A strategy for ternary bioconjugation using inverse electron demand Diels–Alder reaction with tetrazine is studied. Ternary conjugation was demonstrated by the reaction of a model glyco-peptide binary conjugate with a fluorescent tagged olefin.
    共轭反应是一种重要的反应,能够实现分子的耦合。存在许多用于合成两种不同分子之间的二元共轭物或单个分子的多位展示的方案。但对于合成三元共轭物的方法并不多。然而,三元共轭的方法对于理解三个生物分子(或任意三个分子本身)之间的相互作用至关重要。研究了一种利用逆电子需求Diels-Alder反应与四唑进行三元生物共轭的策略。通过模型糖肽二元共轭物与荧光标记的烯烃之间的反应,展示了三元共轭。

    occur through the minor groove of DNA, such as in the calicheamicin or anthracycline families, or through both minor and major groove binders such as in the pluramycins. Here, we demonstrate that carbohydrate-DNA interactions are also possible through sugar capping of a DNA double helix. Highly polar mono- and disaccharides are capable of CH/π stacking onto the terminal DNA base pair of a duplex as shown
    已知碳水化合物-核酸接触是某些药物-DNA识别过程的基本部分。大多数这些相互作用是通过 DNA 的小沟发生的,例如在加利车霉素或环霉素家族中,或者通过小沟和大沟结合剂,例如在多元霉素中。在这里,我们证明了碳水化合物-DNA 相互作用也可以通过 DNA 双螺旋的糖帽化来实现。如核磁共振波谱所示,高极性单糖和二糖能够 CH/π 堆积到双链体的末端 DNA 碱基对上。碳水化合物-DNA 相互作用的能量取决于所涉及的糖的立体化学、极性和接触表面以及末端碱基对。这些结果揭示了碳水化合物-DNA 碱基堆积是用于药物设计的潜在识别基序,

The α-(IIIa) or β-linked glycosides (IIIb-IIIf) with 1,2-trans-configuration were obtained from glycosyl donors with participation of the neighbouring 2-O-acetyl group.

  • An improved synthesis of 1′-[<sup>18</sup>F]fluoroethyl-<i>β</i>-<scp>d</scp>-lactose ([<sup>18</sup>F]-FEL) for positron emission tomography imaging of pancreatic cancer

    日期:2013.6.15
    INTRODUCTION Earlier, we reported syntheses of ethyl-β-D-galactopyranosyl-(1,4')-2'-deoxy-2'-[(18)F]fluoro-β-D-glucopyranoside (Et-[(18)F]FDL) and 1'-[(18)F]fluoroethyl-β-D-lactose ([(18)F]-FEL) for positron emission tomography (PET) of pancreatic carcinoma. Et-[(18)F]FDL requires a precursor, which involves 11 steps to synthesize and produces overall low yields. Synthesis of precursors for [(18)F]-FEL requires
    引言早些时候,我们报道了乙基-β-D-喃半乳糖基-(1,4')-2'-脱氧-2'-[(18)F]-β-D-吡喃葡萄糖苷(Et-[(18) F]FDL) 和 1'-[(18)F] 乙基-β-D-乳糖 ([(18)F]-FEL) 用于胰腺癌的正电子发射断层扫描 (PET)。Et-[(18)F]FDL 需要一种前体,它涉及 11 个步骤来合成并产生总体低产率。[(18)F]-FEL 前体的合成需要四个步骤,但这些前体产生的放射化学产率很低。在这里,我们报告了新的前体和 [(18) F]-FEL 的改进合成。方法 两种前体,1'-(methanesulfonyl)ethyl-2',3',6',2,3,4,6-hepta-O-acetyl-β-D-lactose 2a 和 1'-(p-nitrophenyl-磺酰基)乙基-2',3',6',2,3,4,6-七-O-乙酰基-β-D-乳糖2b,由乳糖分四步合成。使用
  • Study on glycosylated prodrugs of toxoflavins for antibody-directed enzyme tumor therapy
    作者:Shusheng Wang、Dan Liu、Xu Zhang、Shengyu Li、Yongxu Sun、Jia Li、Yifa Zhou、Liping Zhang
    DOI:10.1016/j.carres.2007.03.006
    日期:2007.7
    Eight novel toxoflavin glycosides, which are potential prodrugs in antibody directed enzyme prodrug therapy (ADEPT), were synthesized. The structures of all toxoflavin glycosides were characterized by C-13 NMR spectroscopy, elemental analysis, and MS. Their enzymatic hydrolysis activities were tested against P-glucosidase (EC.3.2.1.21). (C) 2007 Elsevier Ltd. All rights reserved.
