“Molecular Investigation of Pharmaceutical Formulations in Preclinical Development”

Abstract:

Chemical and physical stability of drug substances in pharmaceutical dosages exhibits critical attributes in preclinical development. This presentation will try to elaborate the molecular structure related risks in formulation design and how NMR is employed to tackle these analytical challenges. The contents will cover structural investigation of drug products from solid dosages of small molecule drugs and parenteral formulation of peptides. Chemical and biophysical events including phase conversion of crystalline or amorphous active pharmaceutical ingredients, aggregation of peptides, stabilizing and destabilizing interactions in multicomponent formulations will be discussed. Successful examples utilizing dynamic nuclear polarization (DNP) and proton detection under ultra-fast spinning in practical formulation characterization will be included, as efforts to advance solid-state NMR technologies in pharmaceutical sciences.

“Delineation of Screening Hits by NMR Spectroscopy: The Good, the Bad, and the Ugly

Abstract:

While early-phase hits originate from disparate screening approaches, assay formats and libraries, they share one commonality: the need for direct (i.e. biophysical) on-target binding confirmation. As a biophysical tool, NMR spectroscopy is uniquely situated to provide quality control, direct binding, and mechanistic binding assessments on small molecule hits, in addition to its well-documented application as a fragment screening approach. Case studies will be presented that champion NMR’s ability to detect direct binding of hits when all else fails, isolate hits of preferred mechanism, protect against poor assay reference compound selection, and inform HTS assay design. Vignettes will highlight standard ligand- and protein-observed NMR techniques (e.g. STD, HSQC) along with those of emergent usage, such as 19F observation.

“Relaxing with chronobiology: the role of quantitative NMR spectroscopy in metabolomics studies of sleep and circadian rhythms

Abstract:

Sleep and circadian rhythm studies have recently benefited from metabolomics analyses, uncovering new connections of chronobiology and metabolism. From quantitative nuclear magnetic resonance (NMR) to untargeted mass spectrometry (MS), a diversity of analytical approaches has been applied to elucidating diurnal patterns in metabolites. In this talk, I consider the advances in the metabolomics toolbox which have yielded significant variability in metabolites across multiple sleep and circadian studies, and specifically discuss the role of quantitative NMR spectroscopy. Study design and data processing measures essential for detecting rhythmicity in metabolomics data will also be discussed. I will highlight our studies of circadian metabolism and sleep disorders such as insomnia to provide a practical example of how NMR can be employed in this arena and what benefits it provides. Future developments in these technologies are anticipated vis-à-vis validating these early findings, given that metabolomics has only recently entered the ring with other systems biology assessments in chronobiology studies.

Abstract:

In recent years, benchtop NMR spectrometers have become an increasingly viable alternative to high field systems. Many demanding resolution and sensitivity requirements can now be met with modern methods and instruments. In this seminar, we will present an overview of Magritek’s Spinsolve benchtop NMR and illustrate how several well-established and modern high-field NMR techniques can be implemented on a benchtop NMR system to solve problems and applications previously considered beyond reach.

“Polyethylene Glycol (PEG) Quantitation in Biofluids supporting Drug Discovery”

Abstract:

Conjugation of macromolecular drugs to polyethylene glycol (PEG) improves their therapeutic potential by enhancing the half-life. As a substantial component of the drug, it is necessary to measure the pharmacokinetic (PK) characteristics of PEG in vivo. A quantitative NMR-based method was developed and applied to measuring 40 kDa PEG in serum, enabling determination of PK parameters in preclinical species. Observed half-life was found to be consistent with 125Iodine-labeled PEG methods. Moreover, urinary quantitation of 20kDa PEG  was used to investigate side effects of a pegylated biologic. NMR spectroscopy was shown to be a convenient and reliable alternative to follow pharmacokinetics of PEG in various biofluids.

“Probing molecular architecture and assembly of plant biomaterials with solid-state NMR”

Abstract:

Chemically heterogeneous and structurally amorphous assemblies are essential to
wide-ranging biological tasks that involve water diffusion, mechanical integrity, and protection against pathogenic invasion.  Hydrophobic plant composites, formed by lipid-based polyesters and waxes, assemble into the hydrophilic cell walls and work as an efficient barrier to protect the plant organs from dehydration and injuries.  Of particular interest is the suberin polyester; we have used a combination of genetic modifications and solid-state NMR techniques to decipher the structural frameworks of 13C-enriched suberin materials obtained from Solanum tuberosum L. (potato).  Dynamic nuclear polarization (DNP) strategies are also being developed to enable execution of a broader range of structurally informative experiments on these challenging materials.

Our findings deconstruct the supramolecular organization of this class of biomaterials to shed light on their cooperative dynamics and mechanical performance as well as underscore the design principles of this critical hydrophobic barrier in protective plant tissues.  The results offer potential improvements for both sustainable agricultural practice and bio-inspired materials design.

“Benchtop NMR Pot Luck: Case Studies and Tricks of the Tradees”

Abstract:

Over the past few years, benchtop NMR has elicited significant and rapidly-growing interest. While benchtop NMR instrumentation has been available for two decades, early incarnations were limited to low-resolution Time Domain (TD) applications. Recent advances have made possible the production of benchtop Fourier Transform (FT) NMR spectrometers with higher resolution and sensitivity, offering the potential to expand the reach of NMR beyond dedicated facilities into general laboratory and production settings.

Daniel Barabino  (Oxford Instruments) will discuss some new developments in the works at Oxford Instruments

Frick Chemistry Atrium (dinner) and
Frick Chemistry room A81 (seminar),
Princeton University.
Wednesday, March 16, 2016. [ register ]

Abstract

MRI is a useful tool for studying electrochemical systems because it can be applied to functioning devices in situ and can resolve chemical and spatial informational about components in different phases of matter. I will present our recent work that exploits these advantages of MRI in order to study the growth of dendrites in functioning lithium metal batteries.

Dendrite growth is a serious problem that leads to performance degradation as well as severe safety concerns in rechargeable lithium-ion batteries, and understanding the working conditions under which they form and continue to grow is crucial. By performing 7Li MRI on both the electrolyte and lithium metal electrodes in a functioning lithium metal battery, we have been able to correlate the behavior of the electrolyte concentration gradient to the type and rate of dendrite growth on the surface of the Li electrode, confirming the existence of separate growth mechanisms in different charging regimes.

Due to the rf skin effect, the 7Li metal signal is particularly sensitive to changes at the surface of the electrode. However, the short T2 and low SNR prevent the collection of high-resolution, 3D 7Li images of the dendrites. Instead, we have developed methodology using 1H FLASH imaging to indirectly observe dendritic structures via their impact on the detected signal intensity of the organic electrolyte components. This approach is supported by robust calculation methods that reconstruct the susceptibility and rf field inhomogeneities around the metallic microstructures. The result is a real-time, 3D movie showing dendrites growing across the electrodes in the cell, shedding light on the growth rate and morphology of the structures formed.
