Journal Highlight: Interpretation of seemingly contradictory data: Low NMR S2 order parameters observed in helices and high NMR S2 order parameters in disordered loops of the protein hGH at low pH

Date: Jul 31, 2017

Author: spectroscopyNOW

S2 order parameter-restraining MD simulations have been used to explain the contradictory S2 order parameters for backbone N−H vectors derived from NMR relaxation measurements on hGH at low pH.

Weighing up ways of working out log P

Date: Jul 15, 2017

Author: Ryan De Vooght-Johnson

Lipophilicity is a key parameter affecting the activity of potential drug molecules, but there are many methods to calculate it. Scientists from the University of Belgrade examined various techniques for calculating the lipophilicity of a number of benzothiepino[3,2-c]pyridine derivatives, which were potential antifungal drugs.

Phosphorus rubber: Multinuclear NMR

Date: Jul 15, 2017

Author: David Bradley

Poly-(1-phospha-isoprene) is a phosphorus-containing analogue of natural rubber that might find applications in creating macromolecular gold complexes for use in nanotechnology. 31P{1H} nuclear magnetic resonance (NMR) spectroscopy was used to provide a preliminary structure of the compound.
