Carbohydrates and glycoconjugates

<p>Methyl 2-acetamido-2-deoxy-3-O-(a-D-galactopyranosyl)-a-D-galactopyranoside is a synthetic, fluorinated glycoside that is used as a building block for the synthesis of complex carbohydrates. Methyl 2-acetamido-2-deoxy-3-O-(a-D-galactopyranosyl)-a-D-galactopyranoside can be used in either Click or Fluorination reactions to synthesize oligosaccharides and monosaccharides. It has been shown to react with ethylene glycol to form methyl 2,6 -O-[(3,4,5,6 -tetra‑O‑acetyl‑β‑D‑galactopyranosyl)α -L‑idopyranosyl]-α -L‑idopyranose. Methyl 2,6 -</p>

<p>Sialyl Lewis X (SLeX) is a carbohydrate antigen, related to cell adhesion and it has been shown that inhibition of SLeX synthesis leads to decreased adhesion of trophoblast cells to endometrial epithelial cells (Collins, 2006). Sialyl Lewis X is displayed on the terminus of glycolipids that are present on the surface of white blood cells and it has been shown that SLeX has an important role in inflamation processes. The inital adhesion of white blood cells to a site of injury is mediated by E-selectins which are specific for SLeX. Cell-cell recognition between leukocytes and endothelial cells in blood is believed to occur in part through interactions between lectins and oligosaccharide ligands. SLeX is frequently expressed in human cancer cells and primary tumors. It has been demonstrated that SLeX was involved in the adhesion of tumor cells to vascular endothelium. The potential role of SLeX in the tumor metastatic process has been supported by several clinical studies (Liang, 2016).</p>

<p>Beta-Cyclodextrin is a cyclic oligosaccharide with 7 D-glucose residues which are alpha-1,4-linked. beta-cyclodextrin is used in the food industry to encapsulate flavours and fragrances. Beta-cyclodextrin can increase the water solubility of compounds, such as curcumin; further, the cyclodextrin-curcumin complex also allows for a controlled, sustainable release in a wound healing study.</p>

<p>Di-mannuronic acid sodium salt (β-1,4-linked sodium mannuronobiose) is one of a number of oligosaccharides obtained from alginate which is a polysaccharide in brown seaweeds containing: blocks of repeating mannuronic acid sequences (M-M-M-M etc), repeating guluronic acid sequences (G-G-G-G etc), and alternating M-G-M-G sequences.These oligosaccharides can be released using several methods (Lua, 2015; Yanga, 2004) and claims have been published that mannuronic acid oligosaccharides for example, can be effective in the prophylaxis and treatment of Alzheimer's disease, or for the prophylaxis and treatment of diabetes (USP 8835403B2, 2014).</p>

<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>
