The Faculty of Science Leiden and Leiden Institute of Chemistry are looking for a PhD Candidate.
This PhD position is part of the EU-funded Marie Skłodowska-Curie Doctoral Network (DN) ‘GLYCO-N - GLYCOprotein N-glycosylation from non-life to eukaryotes a Doctoral Network to expand the knowledge on a ubiquitous posttranslational modification of proteins’.

Work and profile

DC 5: Design and synthesis of molecules to interfere with host and viral N-glycosylation processing.

The doctoral project will focus first on the synthesis of improved glycomimetics targeting the essential ER N-glycoprotein folding glycosidases, including ER-alpha-glucosidase I (ER-I) and II (ER-II) and in later stages of the GLYCO-N program glycosidases identified by the N-GLYCO consortium, transferring inhibitor designs to these enzymes. Up until today small molecule glycomimetics targeting host/viral glycoprocessing enzymes were designed as competitive inhibitors, this while arguably (and as evidenced from the field of antibiotics) mechanism-based covalent and irreversible inhibitors would be more effective.

Targeting carbohydrate processing enzymes (CPEs), the enzymes responsible for glycan synthesis and hydrolysis, holds great potential for the development of drugs for a variety of diseases. The Leiden Institute of Chemistry specializes in the discovery and rational design of glycosylhydrolase (GHs) and glycosyltransferase (GT) inhibitors and degraders. This doctoral project will focus on the rational design and synthesis of inhibitors for CPEs involved in N-glycan synthesis. The Ph.D. researcher we are looking for, will be responsible for developing synthetic methodologies to generate new inhibitors and degraders. The generated library of compounds will be tested and used within the DN consortium for glycobiology research.

The selected PhD candidate will experience an international and interdisciplinary training and participate in a series of scientific, technical and complementary skills training events. The position will allow the student to participate in an exciting multidisciplinary research and training programme, enhancing their career perspectives in both the academic and industrial sector.

Selection criteria

  • M.Sc. degree in Chemistry
  • Good knowledge and interest in both organic chemistry and chemical biology;
  • Proven competence in Synthetic Organic Chemistry and Chemical Biology;
  • Knowledge of Synthetic Carbohydrate Chemistry is a plus;
  • Organic chemistry lab skills including Carrying out and monitoring multi-step organic syntheses, purification of small molecules and analytical techniques (NMR, LC-MS).
  • Proficient in English a recognized international certificate in English (TOEFL, TOEIC, etc) is a plus;
  • Excellent communication skills;
  • Ability to work independently and as a team player in a multidisciplinary environment;
