In vitro inhibition of Helicobacter pylori and interaction studies of lichen natural products with jack bean urease

26-May-2018 | Tiago C. A. Lage; Thamilla Maria S. Maciel; Yane C. C. Mota; Francesca Sisto; José R. Sabino; Josué C. C. ..., New Journal of Chemistry, 2018

The interaction of (S)-(−)-usnic acid (2) and fumarprotocetraric acid (3), isolated from Cladonia rappii (lichen), and commercial (R)-(+)-usnic acid (1) with urease was investigated in vitro by molecular spectroscopy at pH 7.4 and kinetics experiments using jack bean type III urease. All lichen ...

Rotational spectroscopy of cold and trapped molecular ions in the Lamb–Dicke regime

26-Mar-2018 | S. Alighanbari; M. G. Hansen; V. I. Korobov; S. Schiller, Nature Physics, 2018

Sympathetic cooling of trapped ions has been established as a powerful technique for the manipulation of non-laser-coolable ions1–4. For molecular ions, it promises vastly enhanced spectroscopic resolution and accuracy. However, this potential remains untapped so far, with the best resolution ...

Understanding and Improving Aggregated Gold Nanoparticles/dsDNA Interactions by Molecular Spectroscopy and Deconvolution Methods

07-Jun-2017 | Jose Maria Carnerero; Aila Jimenez-Ruiz; Elia Grueso; Rafael Prado-Gotor, Physical Chemistry Chemical Physics, 2017

It is well known that single-stranded DNA (ssDNA) is easily able to adsorb on citrate-capped, non-functionalized gold nanoparticles (AuNPs). However, double-stranded DNA (dsDNA)’s affinity to them is much more limited. The present work demonstrates that long dsDNA suffers a bending conformational ...
