  • Unique Self-Anhydride Formation in the Degradation of Cytidine-5′-monophosphosialic Acid (CMP-Neu5Ac) and Cytidine-5′-diphosphosialic Acid (CDP-Neu5Ac) and its Application in CMP-sialic Acid Analogue Synthesis

    compounds except for cytidine‐5′‐monophosphosialic acid (CMP‐Neu5Ac). To obtain an insight into why cytidine‐5′‐diphosphosialic acid (CDP‐Neu5Ac) has not been used for the sialyltransferase reaction and why it is not found in biological organisms, the compound was synthesised. This synthesis provided the interesting finding that the carboxylic acid moiety of the sialic acid attacks the attached phosphate
    唾液酸寡糖是通过各种糖基转移酶和糖核苷酸合成的。所有这些核苷酸都是二磷酸化合物,除了胞苷-5'-单磷酸CMP-Neu5Ac)。为了了解为什么未将胞苷5'-二磷酸(CDP-Neu5Ac)用于唾液酸转移酶反应以及为什么在生物有机体中未发现胞苷,因此合成了该化合物。该合成提供了有趣的发现,即唾液酸羧酸部分攻击连接的磷酸基团。这种相互作用在羧酸磷酸基团之间产生活化的酸酐,并导致焦磷酸键的解。稳定的同位素标记实验证明了该机理。这一发现表明,CMP-Neu5Ac也可能在羧酸磷酸盐之间形成相应的酸酐结构,这似乎就是CMP-Neu5Ac相对于其他糖核苷酸酸不稳定的原因。为了确认羧酸的作用,合成了CMP‐Neu5Ac衍生物,其中唾液酸中的羧酸部分被酰胺基取代。这些类似物显然显示出对酸解的抗性。该结果表明Neu5Ac的羧酸与其在溶液中的稳定性有关。这一发现还为CMP-Neu5Ac和CMP-

    Two new derivatives of glycosyl mitomycin C, 7-N-4-O-(β-D-glucopyranosyl and α-sialosyl)phenyl}-9a-methoxymitosanes, were synthesized, and their structures were elucidated by analysis of the nuclear magnetic resonance spectra. Field desorption mass spectrometry was successfully used for the confirmation of these structures. The cytotoxic, antibacterial, and antitumor activities of 7-N-(4-glycosylphenyl)-9a-methoxymitosanes were also examined.

    surfaces. We report herein the efficient synthesis of the STnThr antigen analogue 2, featuring the immunogenic TnThr mimetic 1 aglycon. Analogously to the native STn, 2 is recognized by the influenza N1 neuraminidase. A model of the N1·2 complex showed the sialyl moiety of 2 well nested in the active site pocket, with docking unaffected by the rigid aglycon. The analogue 2 is, therefore, in association with
    单糖Tn和二糖STn是具有相似结构和共同生物合成途径的肿瘤抗原。两者总是在肿瘤细胞表面同时过表达。我们在此报告了 STnThr 抗原类似物2的有效合成,具有免疫原性 TnThr 模拟物1糖苷配基。与天然 STn 类似,2被流感N1 神经氨酸酶识别。N1· 2复合物模型显示2的唾液酸部分很好地嵌套在活性位点口袋中,对接不受刚性苷元的影响。因此,模拟物2与模拟物1相关联,是设计新的多抗原癌症疫苗的一个很好的决定因素。
  • HI/acetic acid reduction of peracetylated N-acetyl neuraminic acid esters to stereoselectively provide α-2-deoxy-2-hydrido derivatives
    作者:Jacquelyn Gervay、Travis Q. Gregar

    日期:1997.8
    acid were reacted with hydrogen iodide in acetic acid to stereoselectively provide α-2-deoxy-2-hydrido analogs. The reaction proceeds through formation of an anomeric iodide which, in the presence of excess HI, is reduced to give an enol intermediate. Kinetic protonation of the intermediate enol gives a 3.4:1 α:β mixture of 2-deoxy-2-hydrido derivatives. Under thermodynamic conditions the α-anomer
