    摘要1-氨基-1-脱氧-D-甘油-D-古洛糖醇(1),1-氨基-1-脱氧-D-甘油-D-半乳糖-庚糖醇(2)和1-氨基的盐酸盐已经以结晶形式获得了-1-脱氧-D-甘油-L-甘露糖庚糖醇(3)以及游离的氨基庚糖醇2。用亚硝酸对2进行脱氨基反应可得到三种产物:紫苏糖醇(4)和两种似乎是脱水庚糖醇的化合物。脱氨基3得到相似的结果。与公认的规则一致,化合物1和2被醋氧化醋杆菌氧化,而化合物3未被氧化。由2个大概为7-氨基-7-脱氧-L-半乳糖-庚糖(5)的氧化产物已获得结晶。

    The core oligosaccharide component from Mannheimia (Pasteurella) haemolytica serotype Al lipopolysaccharide contains L-glycero-D-manno- and D-glycero-D-manno-heptoses: Analysis of the structure and conformation by high-resolution NMR spectroscopy
    摘要:
    我们实验室以前的研究表明,Mannheimia haemolytica A1型的脂多糖(LPS)含有L-glycero-D-manno-heptose和D-glycero-D-manno-heptose残基。利用1D 1H选择性激发和2D (1H, 13C)和(1H, 31P)杂核实验的NMR方法,对经过无水肼和aq KOH顺序处理后获得的去酰化低分子量LPS的主要核心寡糖组分进行了结构鉴定。发现核心寡糖区由一个分支的八糖和一个3-去氧-4-磷酸-D-manno-oct-2-ulosonate残基连接到去酰化脂质A部分,其结构为[Formula:见文]。在几个连接处存在多样性。NMR方法被设计用于区分庚糖残基的对映异构体形式。合成的L-D-和D-D-heptose单糖被用作模型化合物,以分析1H和13C NMR化学位移和质子偶合常数。使用蒙特卡罗方法进行糖的构象分析的分子建模,用于确定寡糖内部核心的构象,并建立庚糖之间的立体化学关系。 关键词:LPS,NMR,构象,寡糖,庚糖。

  • Reactions of hydroxylated sodium nitronates with acetic anhydride/pyridine
    作者:M.V Berrocal、M.V Gil、E Román、J.A Serrano
    DOI:10.1016/s0040-4020(02)00487-8
    日期:2002.6
    Reactions with Ac2O/Py of sodium nitronate salts derived from primary or secondary nitroalkanes bearing hydroxyl groups at γ or more remote positions have been studied. In all cases, the results could be explained through an acetic nitronic anhydride intermediate, whose evolution depends on conformational factors, and also on the type of the hydroxyl group.
    已经研究了由γ或更远的位置带有羟基的伯或仲硝基烷烃衍生的亚硝酸钠盐与Ac 2 O / Py的反应。在所有情况下,结果都可以通过乙酸乙酸酐中间体来解释,该中间体的演变取决于构象因素,还取决于羟基的类型。

    treatment then provides 76% of D-galactofuranosyl nitromethanes and finally results in the equilibrium of 77% of beta-D-galactopyranosyl nitromethane and 7-9% of three other tautomeric D-galactosyl nitromethanes. Thermal treatment of 7-deoxy-7-nitro-L-glycero-L-galacto-heptitol in boiling water peaks at a 58% content of D-galactofuranosyl nitromethanes and ends in a similar equilibrium mixture of four
    由甲醇钠促进的7-脱氧-7-硝基-L-甘油-L-半乳糖-庚醇过乙酸的甲醇分解反应迅速且几乎定量地积累了7-脱氧-6-O-甲基-7-硝基-L-甘油-L-半乳糖-庚醇。延长的处理然后提供76%的D-半呋喃糖基硝基甲烷,并最终导致77%的β-D-半吡喃糖基硝基甲烷和7-9%的其他三种互变异构体D-半乳糖基硝基甲烷达到平衡。在沸水中对7-脱氧-7-硝基-L-甘油-L-半乳糖-庚糖醇进行热处理时,D-半乳糖呋喃糖基硝基甲烷的含量为58%时达到峰值,并以四个D-半乳糖基互变异构体的相似平衡混合物终止。后一种转换的相关动力学参数是通过使用非线性最小二乘Marquardt-Levenberg算法的曲线拟合确定的。
  • Conserved Inner Core Lipopolysaccharide Epitopes as Multi-Species Vaccine Candidates

    A conserved inner-core oligosaccharide epitope expressed on the lipopolysaccharide (LPS) of a range of disease causing pathogenic bacterial isolates, including Actinobacillus pleuropneumoniae (Ap), Mannheimia haemolytica (Mh) and Pasteurella multocida (Pm), is disclosed. Construction of a mutant bacterial strain exclusively expressing the conserved inner core OS epitope as a terminally exposed structure has allowed the identification, production and isolation of an inner core LPS which is common to all three organisms. Further provided are associated vaccines, antibodies raised against the conserved LPS inner core and glycoconjugates comprising the LPS inner core linked to an immunogenic carrier.
