The present invention provides immunogenic oligosaccharide compositions and methods of making and using them. In particular, the compositions comprise native O-linked and S-linked oligosaccharides coupled to a protein carrier via a linker, wherein the resultant conjugate elicits a protectively immunogenic response, particularly in vaccines against pathogenic
Candida
species and more particularly against
Candida albicans
. Preferably the pathogenic
Candida
species are those that possess cell wall oligosaccharide compositions similar to the β-mannan component of
Candida albicans
cell walls.
The invention relates to novel compounds that have utility as inhibitors of heparan sulfate-binding proteins; compositions comprising the compounds, and use of the compounds and compositions thereof for the antiangiogenic, antimetastatic, anti-inflammatory, antimicrobial, anticoagulant and/or antithrombotic treatment of a mammalian subject.
Novel mannobiose derivative represented by the general formula [I]:
wherein groups of R₁ to R₅ each represents -OH, -OR₆, -NHR₆, (R₆ represents an acyl group) or a group represented by the following formula (a), (b), (c), (d) or (e), provided that one of R₁ to R₅ represents -OR₆ or -NHR₆, one of the other 4 groups of R₁ to R₅ represents one of the groups represented by the formulae (a) to (e), and the remaining 3 groups of R₁ to R₅ represent -OH:
wherein represents α or β bond are provided by the invention.
These compounds give liposomes a specific affinity for Kupffer cells of liver, and can be produced industrially.
