    Synthesis of some amino and carboxy analogs of galabiose; evaluation as inhibitors of the pilus protein PapGJ96 from Escherichia coli
    摘要:
    The 2'-amino-2'-deoxy, 6-amino-6-deoxy, and 6-carboxy analogs of the reference inhibitor 2-(trimethylsilyl)ethyl (alpha-D-galactopyranosyl)-(1-->4)-beta-D-galactopyranoside were synthesized and evaluated as inhibitors of the binding of the Escherichia coli-derived pilus protein PapG(J96), using an ELISA assay. The inhibitory efficiencies (K-rel; relative to the reference inhibitor) were: 157, 13, and < 8, respectively. The results support the previously proposed combining site model, where the protein carries a negatively charged amino acid residue near HO-2' and HO-6 of the galabioside.

    A systematic synthesis of sulfatide (I) and novel sulfatide analogs (II-VI) carrying 2-(tetradecyl)hexadecyl group as a ceramide substitute is described. The 3-O-, 4-O- and 3,4-di-O-levulinoyl derivatives of galactopyranosyl trichloroacetimidates (1, 12, and 13) were coupled with (2S,3R,4E)-3-O-acetyl-2-octadecanamido-4-octadecene-1,3-diol or 2-(tetradecyl)hexadecan-1-ol.
