Oligosacáridos

<p>Lewis X tetrasaccharide (LX4) is a glycan that is found on the surface of human cells. It is an important diagnostic marker for microbial infections and has been shown to be present on the surfaces of both normal skin cells and malignant cells. The presence of LX4 can be detected using a monoclonal antibody in vitro. This glycan can also be used as a model system to study ischemia–reperfusion injury, since it has been shown to be sensitive to oxidative changes caused by reactive oxygen species generated during reperfusion. Studies have also shown that LX4 binds to enzymes such as malonic acid oxydoreductase, which are involved in the metabolism of lysine, arginine, and proline.</p>

<p>β-(1→2)-Oligomannoside constituents of the Candida albicans cell wall have been shown to possess immunostimulatory properties, as evidenced by induction of cytokine production, including tumor necrosis factor (TNF) production, in humans and mice. In particular, oligosaccharide fractions, isolated and fractionated from the C. albicans cell wall, have been shown to induce TNF production in mouse macrophages. Therefore, biological studies employing well-defined synthetic β-(1→2)-linked oligomannoside compounds are of interest for verifying and studying in detail the proposed immunostimulatory properties of such constructs.</p>

<p>2,3,6-Tri-O-acetyl-gamma-cyclodextrin is a custom synthesis of a cyclodextrin. This compound is fluorinated with trifluoromethanesulfonic acid to give the desired product. The methylation of the saccharide is accomplished by reacting it with methyl iodide and sodium hydroxide in an alcoholic solution. The sugar molecule is then glycosylated by reacting it with glycosylation reagent, such as cyanuric chloride or thionyl chloride. Click modification is achieved through the reaction of a glycosylated sugar molecule with azides. Polysaccharides are synthesized by combining glycosylated sugars and polymers into one molecule.BR&gt; CAS No: 30786-38-0BR&gt; Modification: Fluorination, Methylation, Monosaccharide, Synthetic, Click modificationBR&gt; Oligosacchar</p>

<p>Intermediate for synthesis of N-acetyllactosaminic glycans</p>

<p>Hexaacetylchitohexaose is a hexamer of N-acetylgucosamine subunits which are linked by β-(1,4)-glucosidic bonds. N-acetylgucosamine is the monomeric unit of the natural polymer chitin which is degraded by chitinases, in mammals, to form smaller fragments that can induce an immune response. Like chitin and some of its derivatives, hexaacetylchitohexaose is a substrate of lysozymes. Hexaacetylchitohexaose has been shown to significantly inhibit tumour growth in mice by the activation of innate and adaptive immune cells.</p>

<p>Mixed DP 25-50 Na galacturonans, (α-1,4 25-50 Na galacturonans) are derived from pectin or pectic acid, by enzymatic or partial acid hydrolysis. They are used in galacturonic acid metabolism research as a substrate to identify, differentiate, and characterize endo- and exopolygalacturonase(s) and gluconase(s). In recent studies, it has been shown that long oligogalacturonides (degree of polymerization (DP) from 25–50), help to induce plant defense signaling resulting in enhanced defenses to necrotrophic pathogens.</p>
