Abrupt Climate Change and Cultural Transformation

The research in the Biosyn group is focused on the design, synthesis and function of the four major types of biomolecules: nucleic acids, carbohydrates, peptides and lipids and hybrid structures thereof. These biomolecules and their derivatives are used in drug discovery and chemical biology, to develop…

The work described in this Thesis is focused on the assembly of oligosaccharide fragments derived from a fungal polysaccharide, galactosaminogalactan (GAG) and fragments of the exopolysaccharide Pel, generated by Pseudomonas aeruginosa.

Schistosomiasis is an acute and chronic disease caused by blood dwelling parasitic trematodes of the genus Schistosoma, and it is classified as the second most socioeconomically devastating parasitic disease, second only to malaria.

An objective of this research was to achieve direct, well-defined and non-rate-limiting electron transfer between respiratory enzymes and the electrode surface by means of 'Q-wires'.

Het proefschrift omschrijft de chemische synthese van fenolische glycolipiden van verschillende mycobacteriën met het doel om deze te kunnen gebruiken voor immunologisch onderzoek.

Chapter 2 describes a post-synthetic methodology to introduce a fluorescent label in highly lipophilic, Pam3Cys based conjugates.

Cyclic peptides are investigated as a platform to induce different orientations between various ligands.

This project aims at determining the market value of hydrogen peroxide (HP) that is produced via our electrochemical methods that have been developed as part of the ERC-StG Cu4Energy project.

The thesis focuses on synthesis strategies in oligosaccharide campaigns, and the influence of protecting groups.

The work in this thesis has been focused on two subjects. The first is the assembly of alginate oligosaccharides and the generation of building blocks for the enzymatic synthesis of alginate, and the second is the total synthesis of large fragments of the zwitterionic SP1 polysaccharide.

This Thesis describes a strategy to synthesize 1,2-cis-oligosaccharides modulated by additives, such as dimethylformamide (DMF), triphenylphosphine oxide (Ph3P=O) and N-methyl(phenyl)formamide (MPF), using building blocks that carry solely benzyl type protecting groups and are therefore of uniform r…

Implementation of the new sound synthesis and analysis method in music composition.

This Thesis describes the design, synthesis and evaluation as glycoprocessing enzyme inhibitors of focused libraries of iminosugars.

Glycoconjugate vaccines are composed of microbial poly- or oligosaccharides covalently linked to a carrier protein.

In 2018, the number of mobile phone users will reach about 4.9 billion. Assuming an average of 5 photos taken per day using the built-in cameras would result in about 9 trillion photos annually.

Antibiotic resistance, caused by widespread use of antibiotics, leads to bacterial infections that are difficult, if not impossible, to treat and is a major worldwide health concern.

Two excellent young chemists, Jeroen Codée and Sander van Kasteren, have received an ECHO grant for €260,000 from the Netherlands Organisation for Scientific Research (NWO). This funding will allow them to begin their research projects.

This thesis describes the use of a combined approach of computational and experimental techniques to gain novel insights to understand the glycosylation reaction and its reactive intermediates.

Although sugars are widely used in biological and medical research, their synthesis is still badly understood. Jeroen Codée has received a Vici grant of 1.5 million euros for systematically studying the production of sugars. ‘I want to genuinely understand the reactions.’

How are carbohydrates processed by the immune system? Can carbohydrates be used to trigger T-cells against other conjugated antigens? Can they be used as adjuvants?

This thesis presents the first synthetic peptides ADP-ribosylated on serine, threonine, tyrosine, arginine and cysteine.
