Esterified oligosaccharides particularly estersified disaccharides containing a uronic acid residue and a hexosamine residue joined through a glycosidic linkage. Such as useful in cosmetic and pharmaceutical compositions.

Oligosaccharides specific for Chlamydia mediate attachment of the organism to host cells.

Novel compounds with anti-proliferative and mucosaprotective activity are obtained by sulfating trestatins.

Oligosaccharides specific for Chlamydia mediate attachment of the organism to host cells.

The present invention relates to the analysis of unknown oligosaccharides and more particularly the form of analysis in which an unknown oligosaccharide is sequentially brought together with different agents which cause monosaccharides to be cleaved from (or chemically bound to) the oligosaccharide. If cleavage occurs the monosaccharide will subsequentially be detected in the products of the experiment thus confirming that the monosaccharide was attached to the unknown oligosaccharide and provid...

The use of compounds of the formula ##STR1## wherein R is hydrogen or a residue --SO.sub.3 M; M is a cation; and R' and R" are hydrogen or an .alpha.-glycosidically linked sulfated mono- or disaccharide residue; and at least one --SO.sub.3 M group is present per monosaccharide unit, as pharmaceutical compositions for the prevention and/or treatment of arteriosclerotic disorders and for the prevention of restenosis after invasive vascular surgery and after organ transplants.

A process suitable for use in the sequencing of an oligosaccharide compound includes a first analysis of a primary oligosaccharide compound's monosaccharide composition, selection of sequencing agents to apply to the oligosaccharide compound, applying a selected sequencing agent to the oligosaccharide compound, and analyzing a released monosaccharide to select a second sequencing agent. The sequencing agent may be, for example, an enzyme. The oligosaccharide compound may be, for example, an olig...

The invention relates to a method for producing oligosaccharides, comprising selecting a gene which codes for an enzyme which is capable of converting sucrose into an oligosaccharide; linking the gene to suitable transcription-initiation and transcription-termination signals in order to provide an expression construct; transforming a suitable plant cell with the expression construct; regenerating a transgenic plant from the transformed plant cell; culturing the transgenic plant under conditions ...

This invention involves a type of oligosacoharides and its their sulfate derivatives. The backbone of the oligosaccharides consists of 4 to 14 glucose residues, while the side chains contain 0 to 4 glucose residues. There are at least one 1->3.alpha. linkage and .beta.-(1->3)-Iinkage or .beta.-(1->4) linkage in the backbone. These oligosaccharides, and their sulfates have immune enhancing, antitumor, and antiviral activities. They can be used in immune enhancing, antitumor, and antivira...

Separation of anionic oligosaccharides on a preparative scale with high resolution can be achieved by anionic exchange chromatography using PEI-derivatized supports.
