  • Patent number: 5620964
    Abstract: A composition for treating and/or inhibiting gastric and duodenal ulcers, comprising an oligosaccharide selected from the group consisting of Formula I ##STR1## or a mixture thereof; wherein:X is independently OH or NHAc;Y is independently H, or an amino acid or a peptide of 2-100, preferably 2-20, amino acids; andW, W', and W" are each independently H or ##STR2## where Z is independently H or a pharmaceutically acceptable cation; and P is independently H or ##STR3## where Z is defined as above; wherein at least one of W, W' or W" is an .alpha.-N-acetylneuraminic acid moiety, andwherein W' and W" are not simultaneously .alpha.-N-acetylneuraminic acid moietywith the proviso that the compound of Formula II is not NAN .alpha.(2.fwdarw.3)Gal .beta.1-4 Glu or NAN .alpha.(2.fwdarw.6)Gal .beta.1-4 Glu; and a kit for detecting the presence of Helicobacter pylori comprising at least one compound of the Formula I or II, are described.
