Reversing resistance: Rose myrtle extracts analysed by NMR

Date: Mar 1, 2017

Author: David Bradley

Novel natural products found in rose myrtle could hold promise of a new way to make breast cancer cells that have become resistant to the conventional anticancer drug doxorubicin susceptible once more. Nuclear magnetic resonance (NMR) spectroscopy, electronic circular dichroism (ECD) and X-ray crystallography were used to determine the structures and absolute configurations of the compounds.

Portable superconductors: Boost for NMR and MRI

Date: Feb 15, 2017

Author: David Bradley

The confluence of novel materials and a pioneering US discovery with innovation in cryogenics could soon lead to portable and lower-cost NMR and MRI machines, thanks to work at Cambridge University.

Solvents and skin: Solid state NMR of fluid molecules

Date: Feb 1, 2017

Author: David Bradley

Swedish scientists have used solid state nuclear magnetic resonance (NMR) spectroscopy to investigate how individual organic solvent molecules used in skin creams, medicated ointments and cleaning products interact with the biochemistry of human skin and whether or not they can enter the skin.

Journal Highlight: Modelling the transformation of organic materials in soil with nuclear magnetic resonance spectra

Date: Jan 30, 2017

Author: spectroscopyNOW

Solid state 13C NMR spectroscopy gave better predictions of the transformations resulting from adding organic matter to soils than biochemical fractionation and near infrared reflectance spectrometry.

Painting with gumtion: Accelerating art

Date: Jan 15, 2017

Author: David Bradley

J.W.M. Turner used gumtion to make his paintings dynamic. It wasn't simply that he was a dab hand with the brush, he literally used a mixture called gumtion comprising mastic resin with a lead acetate additive to make his oils flow more slicker and smoother across the canvas a spectroscopic study shows.

Sweet substitution: NMR and insulin analogue

Date: Jan 6, 2017

Author: David Bradley

Replacing a particular hydrogen with an iodine atom to create a halogenated insulin analogue maintains the functionality of the glucose-control hormone but makes it act much faster. Nuclear magnetic resonance spectroscopy and X-ray crystallography have been used to investigate the structure.

Journal Highlight: 14N Solid-state NMR spectroscopy of amino acids

Date: Jan 1, 2017

Author: spectroscopyNOW

14N Ultra-wideline solid-state NMR spectra were obtained for 16 naturally occurring amino acids and four related derivatives by using the WURST–CPMG pulse sequence and frequency-stepped techniques.

Bacterial insomnia: NMR finds dormancy inhibitors

Date: Dec 15, 2016

Author: David Bradley

Nuclear magnetic resonance (NMR) spectroscopy and other techniques have allowed an international team to reveal compounds that inhibit the bacterial ability to become dormant. Their work shows for the first time an oxygen-sensitive toxin-antitoxin system that might lead the way to new drugs to defeat bacterial resistance.

The spliceosome: NMR spFRET dice up protein complex

Date: Dec 1, 2016

Author: David Bradley

Prior to gene expression in the cell, the non-coding regions of the genome have to be removed by the spliceosome. A joint single pair Förster resonance energy transfer (spFRET) and nuclear magnetic resonance (NMR) spectroscopy study by researchers in Munich suggests that distinct conformations of a member of this molecular complex play a vital role in the process, with implications for biomedical science.
