Agarose is a polysaccharide found in red algae, typically Gelidium and Gracilaria. It is a strictly alternating polysaccharide of α-1,3 linked D-galactose and β-1,4 linked L-3,6 anhydrogalactose with occasional sulfation at position 6 of the anhydrogalactose residue. Agaro-oligosaccharides result from cleavage at galactose residues and neoagaro-oligosaccharides from cleavage at 3,6-anhydro residues. Neoagarotetraose is reported to have potential for novel cosmeceuticals.

(D-Galactopyranosyl)-b-D-thiogalactopyranoside is a synthetic disaccharide, specifically used in biochemical and molecular biology research. It is often derived through chemical synthesis using various monosaccharide precursors, designed to mimic natural disaccharides with a modified linkage. This compound acts as a non-metabolizable analog of lactose and can inhibit enzymes like β-galactosidase due to its structural similarity. Importantly, its sulfur-containing thiol linkage imparts unique stability and reactivity characteristics distinct from natural glycosidic bonds.The primary application of (D-Galactopyranosyl)-b-D-thiogalactopyranoside is in research studies exploring carbohydrate-protein interactions, enzyme inhibition assays, and the specificity of galactoside-binding proteins. It serves as a tool to elucidate the mechanics of glycosidases and to develop enzyme assays critical for the study of metabolic pathways involving galactosides. Further, it finds use in diagnostics as a reporter substrate in assays where differentiation from native substrates is necessary. Its role in these applications highlights the compound's utility in advancing scientific knowledge of carbohydrate biochemistry.

GT1b (sodium salt) has a core tetrasaccharide structure (Galβ1,3GalNAcβ1,4Galβ1,4Glc) with two sialic acids (NeuAc) linked α2,3/α2,8 to the inner galactose residue, sialic acid (NeuAc) linked α2,3 to the terminal galactose residue and ceramide linked β to position 1 on the reducing terminal glucose residue (Ledeen, 2009). GT1b is one of the major gangliosides in neuronal and glial membranes, it interacts with the myelin-associated glycoprotein (MAG) and is essential for long-term axon-myelin stability. GT1b ganglioside also acts as a receptor for bacterial toxins, such as, tetanus and botulinum toxins (Nishik,i 1996), as well as for viruses, a few examples include: Merkel cell polyomavirus, JC virus, BK virus, norovirus, and others (Low, 2006).

<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>

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.
