Carbohydrate Chemistry and Synthesis

Back to the future: In a biomimetic asymmetric synthesis of sugars (see scheme) sequential cross-aldol reactions of simple aldehydes were catalyzed by amino acids. Deoxysugars were obtained with excellent chemoselectivity and up to >99 % ee. This transformation may implicate a prebiotic catalytic pathway in which amin…

Type 1 (non-neuronopathic) Gaucher disease was the first lysosomal storage disorder for which an effective enzyme replacement therapy was developed and it has become a prototype for treatments for related orphan diseases. There are currently four treatment options available to patients with Gaucher disease, neverthele…

Glycosylation is highly sensitive to the biochemical environment and has been implicated in many diseases including cancer. Glycan compositional profiling of human serum with mass spectrometry has already identified potential biomarkers for several types of cancer and diseases; however, composition alone does not full…

There are approximately 100 known members of the family 3 group of glycoside hydrolases, most of which are classified as beta-glucosidases and originate from microorganisms. The only family 3 glycoside hydrolase for which a three-dimensional structure is available is a beta-glucan exohydrolase from barley. The structu…

Pneumococcal serotypes and their clinical relevanceMats Kalin Pneumococcal disease is endemic all over the world.

Childhood-onset neuronal ceroid lipofuscinoses (NCL) are a group of autosomal recessive progressive encephalopathies characterized by the accumulation of autofluorescent material in various tissues, notably in neurons. Based on clinical features, the country of origin of patients, and the molecular genetic background…

Neuraminidases (sialidases) catalyze the removal of sialic acid residues from sialylated glycoconjugates. We now report that mammalian neuraminidase 1 (Neu1), in addition to its catabolic function in lysosomes, is transported to the cell surface where it is involved in the regulation of insulin signaling. Insulin bind…

Abstract Sulfated polysaccharides are ubiquitous in living systems and have central roles in biological functions such as organism development, cell proliferation and differentiation, cellular communication, tissue homeostasis, and host defense. Engineered sulfated polysaccharides (ESPs) are structural derivatives not…

The success of antitumor and antiviral vaccines often requires the use of an adjuvant, a substance that significantly enhances the immune response to a coadministered antigen. Only a handful of adjuvants have both sufficient potency and acceptable toxicity for clinical investigation. One promising adjuvant is QS-21, a…
