3-D Images of the NOE cross-peaks of H2-H5 and H4-H5 signals from representative hexasaccharides.

The images of NOE cross-peak signals of H2-H5 and H4-H5 from compound 1, 4, 5 and 8 are presented. Cpd 1 and 4 are IdoA2S-containing hexasaccharides and cpd 5 and cpd 8 are IdoA-containing hexasaccharides. The structures of three different conformers for IdoA or IdoA2S are presented on top of the figure, where R represents –H or –SO3H. The calculated distance between H2 and H5, as well as H4 and H5 and displayed in lines with doubled arrows.
