Title: “Dynamic Nuclear Polarization: From Niche Technique to Essential Tool”

Abstract

NMR as a whole, but especially solid-state NMR, can be classed as a “signal-limited” technique – with limited sample volumes, compromises must be made between signal-to-noise ratio and experimental acquisition times. In recent years, a sensitivity revolution has enabled orders-of-magnitude signal enhancements, up to a theoretical maximum of 660- fold, via the Dynamic Nuclear Polarization (DNP) technique. In enabling the gradual easing of the aforementioned compromises, DNP-enhanced SSNMR has enabled studies of systems not previously amenable to solid-state NMR, including whole viruses, amyloid fibrils, membrane proteins, and complex multi-component materials. Yet, the “there is no such thing as a free lunch” mantra also applies — DNP-NMR is not without its pitfalls, generally requiring specialized hardware and modifications to the sample that can impact spectral resolution. Extensive efforts have gone into mitigating these pitfalls and maximizing the sensitivity gains available, especially as the field moves to ever higher magnetic fields. Recent investigations of previously under-explored facets of the technique, for instance direct enhancement of nuclei other than 1H, hint that we have only scratched the surface in terms of the capabilities and potential of DNP. In this talk, I will present:
  • An overview of the technology and mechanisms behind DNP, including recent advances at high magnetic field and low microwave power
  • A brief practical discussion of the state-of-the-art in sample preparation for various DNP applications
  • Recent work in 19F-DNP, with potential implications for the field as a whole
  • Perspectives for the future: combining DNP, ultrafast magic angle spinning (MAS), and selective excitation to revolutionize sensitivity and resolution

Title: “Investigating Molecular Mechanisms of Drug Delivery and Stability from Solid-state NMR

Abstract

Structural details often provide molecular mechanisms to construct the interplay among biology, chemistry and engineering for drug product development. Solid-state NMR analyzes a wide range of drug and wet pharmaceutical materials from small molecule medicines to biological products. The obtained structural information at macroscopic and microscopic scales offer critical knowledge for understanding and optimizing drug delivery, chemical and physical stability, bioavailability, formulation composition, and manufacturing process. This presentation will provide examples to introduce the molecular structure mediated questions in pharmaceutical sciences and elaborate how ssNMR techniques are employed to tackle these analytical challenges.

Title: “Dynamics and Disorder in α-Synuclein Amyloid Fibril Aggregation and Seeding

Abstract

Amyloid fibril formation and propagation of α-Synuclein (αS) is associated with the progression of multiple neurodegenerative diseases, including Parkinson’s Disease. Cell-to-cell spread of αS fibrils is thought to contribute to disease progression, which leads to “seeding” or templated misfolding endogenous αS monomer through processes such as templated elongation and secondary nucleation. The molecular level details of these seeding mechanisms and the interactions that drive the aggregation process are not fully understood, but will be critical in not only fully understanding the process of seeding but also in identifying potential avenues of therapeutic disruption. In this talk, I will describe some of our recent efforts to characterize the interactions between monomeric αS and αS amyloid fibrils using a combination of solution NMR and solid-state NMR techniques. I will describe how combining NMR measurements of relaxation, exchange, and water accessibility with other biophysical measurements of protein aggregation and cell toxicity has led to the identification of a common aggregate binding site on αS monomers, as well as the role that dynamics can play in the ability of amyloid fibrils to template aggregation.

Sep 23, 2020 – NMR Topical Group Meeting

Speaker: Dr. Alexander Marchanka, Junior Professor, Institute of Organic Chemistry, Leibniz Universität, Hannover, Germany

Title: “Solid-state NMR approach for structural studies of RNA”

Abstract

Large RNA molecules are challenging objects for structural biology. Solid-state NMR (ssNMR) can provide valuable structural information for large biomolecules at atomic resolution and holds great promises for structural studies of both lone RNA and RNA in complex with proteins (ribonucleoproteins, RNP). In this talk I will present our novel ssNMR methodology for structural characterization of RNA which includes sophisticated isotope labeling of RNA and acquisition of multidimensional heteronuclear correlation spectra. Additionally to conventional 13C and 15N detected ssNMR experiments we apply novel ultrafast magic angle spinning (MAS), 1H-detected ssNMR spectroscopy for structural studies of RNA. Ultrafast MAS coupled with 1H-detection extends the range of available experiments, allows deeper insights into structure and functional dynamics and significantly reduces the amount of laboratory and instrument times. Furthermore, we apply paramagnetic relaxation enhancement (PRE) to characterize protein-RNA interfaces by ssNMR. Finally, I will provide a few examples of studies on RNA, protein-RNA and RNA-RNA complexes by ssNMR and complementary techniques.

Title: “Deuterium Metabolic Imaging (DMI), a novel MR-based method to map metabolism in 3D”

Abstract

Non-invasive imaging of metabolic pathways in neurological disease has been a long-standing goal to monitor disease progression or therapy efficacy. Positron emission tomography (PET) in combination with 2-18F-fluoro-2-deoxy-D-glucose (FDG) is currently the only clinically viable metabolic imaging method. However, the high uptake of FDG by normal brain drastically reduces the image contrast and the usefulness of FDG-PET in studying neurological disease. MR-based methods (1H, 13C, hyperpolarized 13C MRS) are promising but have failed to reach clinical significance due to technical complexity and lack of robustness and/or sensitivity. Deuterium metabolic imaging (DMI) is a novel MR-based method that uses the favorable MR characteristics of deuterium to map metabolism in vivo in 3D. The low intrinsic sensitivity of 2H NMR is offset by favorable T1 and T2 relaxation times, a large nuclear spin and a sparse NMR spectrum devoid of strong water and lipid signals. By combining 2H NMR with deuterated glucose administration (oral or intravenous), MR spectroscopic imaging and signal quantification through spectral fitting we were able to generate deuterium metabolic images of brain, brain tumor and liver metabolism in vivo. Our first-in-human DMI maps of glucose metabolism in healthy brain and in patients with high grade brain tumors illustrate that DMI has the potential to become a robust and widely applicable brain imaging method with strong clinical utility

Feb 19, 2020 – NMR Topical Group Meeting

Featured PresentationDr. Abby R. O'Connor

Speaker: Dr. Abby R. O’Connor, Associate Professor, Department of Chemistry, The College of New Jersey

Title: “Examining sulfonamide containing ligand scaffolds in catalytic base-free transfer hydrogenation and beyond !”

Abstract

Work in the O’Connor lab has focused on the catalysis of iridium complexes containing pyridinesulfonamide ligands. We discovered iridium-catalyzed transfer hydrogenation of polar substrates under conditions that do not require basic additives and rigorously dried and degassed substrates and solvents. These catalysts tolerate a wide substrate scope and including base sensitive functional groups. Variation of the electronics of the catalysts and substrates influences the yield of product, as determined by 1H NMR spectroscopy. Control experiments support a homogeneous catalyzed pathway. Variation of the structural rigidity of the ligand framework has been explored and high catalysis activity is only observed with flexible ethylene or methylene linkers between the sulfonamide and pyridine moieties; substitution with a more rigid aromatic linker prevents catalysis (Figure 1). Initial NMR spectroscopic studies support the formation of an iridium hydride intermediate and the potential for ligand dissociation under catalytic conditions. Our preliminary mechanistic and kinetic findings via experiment and theory are highlighted to provide an explanation as to why these systems operate under base-free conditions. Also highlighted in this presentation are new ligand scaffolds being developed by our lab for rare earth element binding and recovery and CO2 reduction
