    ends meet: The L‐gulopyranosyl trichloroacetimidate and 1,6‐anhydro‐2,3‐di‐O‐benzyl‐β‐L‐gulopyranose, efficiently derived from L‐ascorbic acid, were individually used as a starting unit and an elongation unit to prepare L‐guluronic acid linked alginate oligosaccharides in excellent α selectivity and in good yields.

  • L-beta-dioxolane uridine analogs and methods for treating and preventing virus infections
    申请人:Yale University and The University of Georgia Research Foundation, Inc.
    公开号:US20010018440A1
    公开(公告)日:2001-08-30
    The present invention relates to the discovery that certain P-L-dioxolane nucleoside analogs which contain a uracil base, and preferably, a 5-halosubstituted uracil base, exhibit unexpectedly high activity against Epstein-Barr virus (EBV), Varciella-Zoster virus (VZV) and Herpes Virus 8 (HV-8). In particular, the compounds according to the present invention show potent inhibition of the replication of the virus (viral growth) in combination with very low toxicity to the host cells (i.e., animal or human tissue). Compounds are useful for treating EBV, VZV and HV-8 infections in humans.
    本发明涉及发现某些含有尿嘧啶碱基的P-L-二氧兰核苷类似物,尤其是含有5-卤代尿嘧啶碱基的类似物,对于Epstein-Barr病毒(EBV)、痘带状疱疹病毒(VZV)和人类疱疹病毒8(HV-8)表现出意外的高活性。特别是,本发明的化合物在对宿主细胞(即动物或人体组织)的毒性非常低的情况下,显示出对病毒复制(病毒生长)的强效抑制。这些化合物对于治疗人类EBV、VZV和HV-8感染非常有用。

  • On the Regioselective Acylation of 1,6-Anhydro-β-<scp>d</scp>- and<scp>l</scp>-Hexopyranoses Catalysed by Lipases: Structural Basis and Synthetic Applications
    作者:Nathalie Boissièere-Junot、Charles Tellier、Claude Rabiller
    DOI:10.1080/07328309808005771
    日期:1998.1
    With the aim of providing new methods for the regioselective protection at the 2, 3 and 4 positions of monosaccharides, we have studied the acetylation of a class of rigid sugars: the 1,6-anhydro-beta-D- and L-hexopyranoses (hexopyranosanes D-l to D-5 and L-1 to L-5), using vinyl acetate as an acyl donor and two common lipases,Candida rugosa and Pseudomonas cepacia, as catalysts. Our results indicate that the relative orientation of the hydroxyls governs the regioselectivity of acetylation. In the D-series, when the 3-OH is in the axial position, acetylation occurs mainly at the 4-axial OH, while the 2-axial OH is preferred when the 4-OH is equatorial. Conversely, when the 3-OH is equatorial, a strong selectivity affects the equatorial 2-OH. Compounds of the L-series were shown to be poor substrates for the lipase Pseudomonas cepacia except for L-galactosane for which the 2-monoacetyl ester was obtained in good yield. An attempt to rationalize the results by means of molecular modelling is also made to account for the catalytic activity of the Candida rugosa lipase on hexopyranosanes 1-3.
