Bioactive macrocycles: NMR structures

Date: Jun 1, 2016

Author: David Bradley

Bioactive peptidomimetic macrocycles have been developed by a group of scientists at Cornell University in Ithaca, New York, USA, and studied using nuclear magnetic resonance (NMR) spectroscopy.

Journal Highlight: Authentication of the origin of sucrose-based sugar products using quantitative natural abundance 13C NMR

Date: May 30, 2016

Author: spectroscopyNOW

A direct 13C nuclear magnetic resonance (NMR) method can differentiate between sucrose-based sugar products produced from sugar beet (C3 plant) and sugar cane (C4 plant), providing an alternative to isotope ratio MS.

It's a stitchup: Evolving new proteins

Date: May 15, 2016

Author: David Bradley

Scientists in the USA are stitching together novel proteins from fragments in an evolutionary manner and using nuclear magnetic resonance (NMR) spectroscopy and X-ray crystallography to examine the results.

Journal Highlight: Ultrafast Multidimensional Laplace NMR Using a Single-Sided Magnet

Date: May 2, 2016

Author: spectroscopyNOW

Ultrafast single- and multidimensional Laplace NMR experiments, based on spatial encoding, are shown to be viable with low-field, single-sided magnets with an inhomogeneous magnetic field.

Gut feeling: NMR reveals PTSD link?

Date: May 1, 2016

Author: David Bradley

A nuclear magnetic resonance (NMR) spectroscopy by researchers at McMaster University in Ontario, Canada, hints at a possible link between the bacteria growing in your gut and neurological conditions such as post-traumatic stress disorder (PTSD), anxiety and perhaps even depression.

All four corners: NMR and chiral carbons

Date: Apr 15, 2016

Author: David Bradley

A new approach to chiral synthesis that works under mild conditions has been validated with nuclear magnetic resonance (NMR) spectroscopy and other tools by scientists in Europe. Paolo Melchiorre of ICIQ, Institute Of Chemical Research Of Catalonia, and colleagues developed the technique using enantioselective iminium ion chemistry and photoredox catalysis to form quaternary carbon stereocentres with high enantioselectivity.

Journal Highlight: Ultrafast magic-angle spinning: Benefits for the acquisition of ultrawide-line NMR spectra of heavy spin-1/2 nuclei

Date: Apr 4, 2016

Author: spectroscopyNOW

The benefits of the ultrafast magic-angle spinning approach for the acquisition of ultrawide-line NMR spectra have been demonstrated for tin oxide and a tin complex.

Pain on the brain: NMR tracks analgesics

Date: Apr 1, 2016

Author: David Bradley

Nuclear magnetic resonance spectroscopy (NMR) can be used to measure brain metabolites following administration of painkillers and so provide a useful way to evaluate objectively the analgesic effect as well as to study the mode of action of old and new types of painkiller.

Zinc control: NMR untangles Alzheimer's

Date: Mar 15, 2016

Author: David Bradley

An important clue as to the underlying mechanism of Alzheimer's disease has been identified using nuclear magnetic resonance (NMR) spectroscopy by researchers from the Lomonosov Moscow State University scientists and their colleagues from the Institute of Molecular Biology, Russian Academy of Sciences and the King's College London. They report details in the journal Scientific Reports.

Journal Highlight: Rapid NMR assignments of proteins by using optimized combinatorial selective unlabeling

Date: Mar 8, 2016

Author: spectroscopyNOW

A new approach for rapid resonance assignments in proteins based on amino acid selective unlabeling can augment existing approaches and will be useful for identifying active-site residues involved in ligand binding, phosphorylation, or protein–protein interactions.
