Forschungszentrum Jülich

Blick auf das 900 MHz-NMR-Gerät im Biomolekularen NMR-Zentrum, das gemeinsam vom Forschungszentrum Jülich und der Heinrich-Heine-Universität Düsseldorf betrieben wird. Das Magnetfeld im Innern hat eine Stärke von 21 Tesla und ermöglicht hochempfindliche NMR-Experimente zur Aufklärung der 3D-Struktur und Dynamik von Proteinen und ihren Komplexen mit Wirkstoffen und anderen Liganden.

At FZJ, diagnostics and therapeutics are being developed for inflammatory and degenerative CNS, infectious, and tumour diseases. Methodological focus is set on structure-based drug research, radio chemistry, and image based procedures for drug studies. In the areas of x-ray crystallography, as well as in liquid and solid state NMR spectroscopy, structural biology research is carried out at the highest international level.

Together with the Heinrich-Heine-University Düsseldorf (HHU) FZJ is running the Biomolecular NMR Center, which is one of the leading NMR centres in Germany and is an important partner within the Roadmap Structural Biology of the Helmholtz Association. One focus of the structural biological investigations is set on the characterization of protein ligand complexes and membrane proteins. In addition, chemical-analytical (LA-ICP-MS, AAS, GC-MS, LC-MS, FTICR-MS) and molecular biological methods (mirror image phage display) and innovative imaging techniques using high-end devices (high field MRI and PET hybrid approaches for humans and rodents) are applied.

Ultrasensitive assays for CSF and blood based lab diagnostics of neurodegenerative diseases (M. Alzheimer, M. Parkinson) are being developed. Clinical imaging procedures are the focus of the in vivo diagnostic approaches towards an early presymptomatic identification of neurologic and psychiatric diseases (schizophrenia, PSP, MSA, M. Alzheimer) as well as brain tumours. This includes research on radio diagnostic probes for molecular imaging using PET (amyloid imaging in dementias) and tracers for novel contrast agents to be used in high field MRI. Evaluated target structures and effectors are tested preclinically in model organisms and clinically in phases I to IIb (according to AMG).

The FZJ segment of the radionuclide based drugs creates a unique feature of the Helmholtz Association compared to other research collaboratives.
