Characterization of Stratum Corneum Molecular Dynamics by Natural-Abundance 13C Solid-State NMR
Despite the enormous potential for pharmaceutical applications, there is still a lack of understanding of the molecular details that can contribute to increased permeability of the stratum corneum (SC). To investigate the influence of hydration and heating on the SC, we record the natural-abundance (13)C signal of SC using polarization transfer solid-state NMR methods. Resonance lines from all ...
متن کاملHydrogen-Bonding Interactions in T-2 Toxin Studied Using Solution and Solid-State NMR
The structure of T-2 toxin in the solid-state is limited to X-ray crystallographic studies, which lack sufficient resolution to provide direct evidence for hydrogen-bonding interactions. Furthermore, its solution-structure, despite extensive Nuclear Magnetic Resonance (NMR) studies, has provided little insight into its hydrogen-bonding behavior, thus far. Hydrogen-bonding interactions are often...
متن کاملNMR Studies on the Properties of Polymers in Supercritical CO2
Using NMR spectroscopy and NMR imaging, the behaviour of polymers in supercritical CO2 (sc-CO2) using a custom-made cell designed from poly(ether ether ketone) (PEEK) has been observed. The mechanism of swelling of polymers in sc-CO2 and the overall effects of sc-CO2 on the transport properties of both small and large molecules has been studied. We report on the swelling characteristics of radi...
متن کاملProtonation, tautomerization, and rotameric structure of histidine: a comprehensive study by magic-angle-spinning solid-state NMR.
Histidine structure and chemistry lie at the heart of many enzyme active sites, ion channels, and metalloproteins. While solid-state NMR spectroscopy has been used to study histidine chemical shifts, the full pH dependence of the complete panel of (15)N, (13)C, and (1)H chemical shifts and the sensitivity of these chemical shifts to tautomeric structure have not been reported. Here we use magic...
متن کاملIdentifying the intermolecular hydrogen-bonding supramolecular synthons in an indomethacin-nicotinamide cocrystal by solid-state NMR.
Two-dimensional (1)H double-quantum and (14)N-(1)H & (1)H-(13)C heteronuclear magic-angle spinning (MAS) NMR spectra recorded at natural isotopic abundance identify specific intermolecular COOH···N(arom) and CH(arom)···O=C hydrogen-bonding interactions in the solid-state structure of an indomethacin-nicotinamide cocrystal, thus additionally proving cocrystal formation.
