Advances in carbohydrate chemistry have certainly made common oligosaccharides much more accessible. Equipped with world-leading technology platforms and professional scientific staff in glycan synthesis, Creative Biolabs is committed to offering high-quality custom oligosaccharide and oligosaccharide derivatives synthesis services to promote the progress of oligosaccharide related projects.

Importance of Oligosaccharide

Oligosaccharide sequences are found in numerous natural compounds and constitute the core of many therapeutics. They are involved in a wide range of biological processes, including bacterial and viral infection, cancer metastasis, the blood-clotting cascade, and many other crucial intercellular recognition events. The presence of glycans in glycoproteins, glycolipids, glycosaminoglycans, and other conjugates presents a treasure of potential information on cellular differentiation and condition. Over half of all proteins in the human body are N- or O-glycosylated, and cell surfaces present a rich multitude of glycolipids and glycosaminoglycans. Oligosaccharides carrying information on biological significance are found in body fluid, on cell surfaces, and within cells.

Applications of Oligosaccharides in Glycomedicine

Custom Oligosaccharide Synthesis

A major obstacle in glycomedicine is the lack of pure and structurally well-defined oligosaccharides. These compounds are usually in low concentrations and in microheterogeneous forms, which make the isolation and characterization complicated. Based on chemical or enzymatic synthesis methods, well-defined oligosaccharides have been obtained in many cases. Such compounds are increasingly used to address important problems in glycobiology research and for drug discovery. For example, chemoenzymatic approach for the preparation of a library of over 400 oligosaccharides using array technology has been employed for profiling the specificity of a diverse range of glycan-binding proteins.

Synthetic oligosaccharide epitopes offer promising possibilities for the development of vaccines for the prevention of infectious diseases, including human immunodeficiency virus (HIV), Haemophilus influenzae type b, Plasmodium falciparum, Cryptococcus neoformans, Vibrio cholerae, Streptococcus pneumoniae, Neisseria meningitides, Candida albicans, and Bacillus anthracis. These oligosaccharides have also been employed for the development of therapeutic vaccines for cancer. The over-expression of oligosaccharides, such as Tn antigen, is a common feature of oncogenic transformed cells. A broad of preclinical and clinical studies have demonstrated that antibodies against carbohydrate-associated tumor antigens are able to eliminate circulating tumor cells and micro-metastases in cancer patients.
