“The Tveskaeg benchtop NMR instrument: Multinuclear, cost-efficient NMR for industry and science“

Abstract

Nuclear magnetic resonance (NMR) is a powerful tool for quantitative molecular analysis. While high-field NMR spectrometers are based on bulky superconducting magnets, several low-field NMR instruments (based on permanent magnets) have been developed as robust, mobile, low-cost alternatives. The vast majority of low-field NMR instruments are limited to 1H experiments sometimes combined with a narrowband channel for another high-sensitive isotope. However, practical applications of NMR exist for a large variety of detection isotopes.

To utilize this potential, we have developed a cost-efficient, benchtop/on-line NMR instrument with a broadband channel covering the frequencies of all relevant NMR-active isotopes with fast digital tune/match capability. The Tveskaeg NMR instrument (NanoNord A/S, Denmark) is based on a ~1.5 T permanent Halbach magnet, a digital console, and a probe with 2 ml sensitive sample volume (i.d. 9.2 mm). The instrument is suitable for use in laboratories, for fieldwork, and in on-line setups for continuous monitoring applications.

Targeting specific industrial applications, we have conducted a variety of studies to demonstrate the performance of the NMR instrumentation in the laboratory and at industrial positions of use. Some of these applications are: (i) On-line monitoring of catalytic fines in heavy fuel oil onboard ships using 27Al NMR. (ii) Continuous monitoring of ammonium, phosphorus and chloride levels at wastewater treatment plants by 14N, 31P and 35Cl NMR. (iii) Quantification of nutrients in agricultural manure by 14N, 17O, 31P and 39K NMR. (iv) Quantification of salt in food products by 23Na and 35Cl NMR. (v) Quantification of protein and fat contents in milk. (vi) Monitoring of boron and lithium in reactor coolant at power plants by 11B, 10B and 7Li NMR.

Furthermore, the benchtop instrument is an efficient spectrometer for wide-line solid-state NMR experiments. The is demonstrated experimentally by acquisition of challenging spectra like the 14N spectrum of KNO3 spanning more than 1 MHz. By introducing interleaved sampling of frequency slices, a highly efficient acquisition is achievable with a sensitivity comparable to high-field NMR experiments.

Overall, our results demonstrate some of the capabilities and the versatility using multinuclear, cost-efficient NMR as a robust analytical tool suitable for both scientific and large-scale industrial applications.

“NMRFx: A new integrated software suite for NMR data analysis with applications to biomolecular NMR”

Abstract

Knowing the structure, dynamics and ligand binding specificity of proteins and nucleic acids is essential to understanding the mechanisms of human disease and to the optimal design of molecules that can intervene therapeutically in disease processes.  Nuclear Magnetic Resonance (NMR) Spectroscopy is one of the most versatile techniques for obtaining this molecular information.  The optimal use of this information requires complex data analysis including signal processing, chemical shift assignment and structure calculation.  In this talk I’ll describe our work on a new integrated software suite for NMR data analysis.  This new software, NMRFx, is a cross platform tool running on MacOs, Linux and Windows and builds on our previous experience in developing NMRviewJ.  I’ll illustrate the software suite with applications to the assignment of RNA molecules that incorporates data processing, chemical shift prediction and a new visual assignment tool that has applications to RNA, peptides and medicinal chemicals.

“Identification of Biologically Relevant Scaffolds and their Binding Modes”

Abstract

The NMR is an invaluable technique that can be implemented at the different stages of drug discovery process, ranging from identification of new drug lead to optimization of their binding pharmacophore and establishment of their structure-activity relationships. My research interests have evolved around different aspects of NMR application to drug discovery. To date I worked in two different research areas: biological testing, isolation, structure elucidation of natural products and development of Intermolecular NOEs for Pharmacophore Mapping (INPHARMA ) method enabling determination of the ligand binding mode. Therefore, in the first part of my talk I will demonstrate the extended scope of natural products isolation and elucidation to very limited quantities of pure metabolites. In the second part of my talk I will cover application of INPHARMA method for the identification of ligand binding poses with accuracy high enough to be applicable for pharmacophore design and virtual screening.

“Resolving the Dynamic Dance between Proteins and Solvent using NMR and Reverse Micelles”

Abstract

The critical role of solvent in thermodynamically driving protein structure and function has long been recognized, yet significant controversy persists over the details of how water interacts with proteins. This fundamental gap in our basic understanding of protein systems is largely due to the paucity of experimental data regarding how water and proteins move with respect to one another at the atomic level. While the enthalpic contributions to protein structure-function relationships are well understood, the entropic contributions remain largely a mystery and the fast dynamics of water and protein provide an important window to entropy. Recent studies using nuclear magnetic resonance (NMR) have shed exciting new light on the entropic nature of proteins and of their solvating water. These experiments have revealed a likely functional role for the internal entropy of proteins and for the entropy of the water that solvates them. These recent findings and their implications for understanding protein function will be discussed. New studies using NMR and fluorescence techniques to understand anomalous diffusion in cells will also be summarized.

“Inhibitor Bound Dengue NS2B-NS3pro Reveals Multiple Dynamic Binding Modes”

Abstract

Dengue virus poses a significant global health threat as the source of increasingly deleterious dengue fever, dengue hemorrhagic fever, and dengue shock syndrome. As no specific antiviral treatment exists for dengue infection, considerable effort is being applied to discover therapies and drugs for maintenance and prevention of these afflictions. The viral genome encodes the enzyme to carry out cleavage of the large polyprotein, specifically the NS2B-NS3pro cofactor-protease complex—a target of high interest for drug design. One class of recently discovered NS2B-NS3pro inhibitors is the substrate-based trifluoromethyl ketone containing peptides. These compounds interact covalently with the active site Ser135 via a hemiketal adduct. A detailed picture of the intermolecular protease/inhibitor interactions of the hemiketal adduct is crucial for rational drug design. We show, through the use of protein- and ligand-detected solution-state 19F and 1H NMR methods, an unanticipated multibinding mode behavior of a representative of this class of inhibitors to dengue NS2B-NS3pro. Our results illustrate the highly dynamic nature of both the covalently bound ligand and protease protein structure, and the need to consider these dynamics when designing future inhibitors in this class.

“Using Very Fast Spinning and Proton Detection to Solve Protein Structures with Solid-State NMR”

Abstract

Solid state NMR of biological systems is a rapidly expanding field that is tightly connected with improvements in hardware. The advantage of ssNMR as a technique is in its ability to address the structures of insoluble, noncrystalagraphic systems at atomic resolution. This is possible because of magic angle spinning, which averages anisotropic interactions leaving behind the sharp isotropic signals seen in solution NMR. In the last decade, the maximum MAS rates have increased first from 20 to 40 kHz, then to 60 kHz and very recently to 100+ kHz. As a result, new techniques have become available, one of which is proton detection. I’ll discuss my work using proton detected ssNMR on membrane proteins in lipid bilayers. This will include optimization of pulse sequences and sample preparation, as well as computational improvements to aid in structure determination.

“Metabolomics:  A Tool for Drug Discovery, Disease Diagnosis and Systems Biology”

Abstract

Metabolomics is an invaluable tool of systems biology and has made significant contributions to a diverse number of fields, such as drug discovery, disease diagnosis, and personalized medicine. Unlike other OMICs techniques, an observed difference in the metabolome is directly correlated with a relevant biological response (a change in the biological activity of protein). The metabolome captures how the system responds to drug treatment, disease state, environmental stress or genetic modification. As a consequence, the application of metabolomics has increased exponentially over the last decade. A diseased-centered systems biology approach to drug discovery provides a unique infrastructure to identify novel druggable targets and therapeutic agents to increase the efficiency and success rate of drug discovery. One important component of this approach is the use and development of NMR and MS based metabolomics techniques to monitor the in vivo activity and selectivity of potential drugs. Similarly, metabolomics can be used to monitor disease development, identify in vivo mechanisms of action for novel drugs, and evaluate mechanisms of drug resistance. Additionally, metabolomics may be an invaluable approach to easily and rapidly diagnose human disease and assist in personalized medicine by monitoring a patient’s response to a particular treatment. Our metabolomics technology, including our MVAPACK metabolomics software platform, PCA/PLS-DA utilities, and protocols for integrating NMR and MS data, sample preparation and metabolite identification will be discussed. Also, our analysis of the mechanism of action and resistance of TB and cancer drugs, and metabolic processes related to pancreatic cancer, Parkinson’s disease and a potential diagnostic tool for multiple sclerosis will be presented.
