CNRS research unit whose research activities focus on chemistry and biology.

It is part of Université Paris-Saclay.

ICSN is located on the Gif-sur-Yvette campus and has approximately 125 staff members, including 70 permanent researchers and staff, distributed across three buildings.

Within the Department of Chemical Biology, the successful candidate will join the carbohydrate chemistry research team to work under the supervision of the team leader, and the project will be jointly supervised by two researchers.

The laboratory is equipped with all the facilities required to carry out the project, including HPLC, automated flash chromatography, a microwave synthesis reactor, a freeze dryer, a rotary evaporator, and other equipment.

Several analytical platforms are available within the institute and provide access to state-of-the-art instrumentation, including NMR spectroscopy (300 and 500 MHz), mass spectrometry (LC-MS and HRMS), and X-ray diffraction.

Synthesis of N-Acetylglucosamine Analogues as Therapeutic Agents As part of the ANR Gb3Down project, which brings together the

ICSN in collaboration with the Institut Curie, the University of Versailles Saint-Quentin-en-Yvelines (hospital), and a pharmaceutical company, we propose the synthesis of N-acetylglucosamine analogues as therapeutic agents.

Scientific results have led to the identification of an N-acetyl-glucosamine-based “hit” compound as an active molecule in Fabry disease and in the production of the glycosphingolipid Gb3. The project will focus on optimizing the molecular structures in order to improve their pharmacological properties and biological activities in cellular assays and subsequently in vivo.

The candidate will be responsible for the synthesis of these N-acetyl-glucosamine analogues, incorporating modifications at the anomeric position, on the amino group, or on the hydroxyl groups, using appropriate selective protection/deprotection strategies.

The compounds will be characterized, in particular, by NMR spectroscopy and mass spectrometry, and their biological activities will then be evaluated in close collaboration with the project partners.

The ideal candidate will hold a Master's degree (M2) in Organic Chemistry, Medicinal Chemistry, or an equivalent qualification, with a specialization in organic synthesis and/or glycochemistry.

Demonstrated experience in multi-step synthesis (including protection/deprotection and glycosylation) will be highly appreciated, as well as strong proficiency in analytical techniques such as NMR, mass spectrometry, and

HPLC.

An interest in medicinal chemistry and therapeutic applications would be an additional asset.

The candidate should also demonstrate autonomy, rigor, and the ability to work effectively within a multidisciplinary team involving chemists and biologists.

Good scientific writing skills, including the preparation of regular reports, as well as strong oral presentation skills, are also expected.
