In this research at the first (RS)-1-[4-(2-Methoxyethyl)phenoxy]-3-[(propan-2-yl)amino]propan-2-oland its fullerene derivative were optimized. NBO calculations and NMR for the complexes were carried out at the B3LYP/6-31G*quantum chemistry level. Different parameters such as energy levels, the amount of Chemical Shift in different atoms, the amount of HOMO/LUMO, chemical potential (µ ), chemica...

In this research at the first 2-amino-3-(3,4-dihydroxyphenyl)-2-methyl-propanoic acid  drug and its fullerene derivative were optimized. NMR calculations for the complexes were carried out at the B3LYP/6-31G*quantum chemistry level.

Nuclear magnetic resonance (NMR) spectroscopy is one of the techniques used in structural biology and drug discovery. A critical step in analysis of NMR images lies in automation of assigning NMR signals to nuclei in studied macromolecules. This procedure is known as sequence-specific resonance assignment and is carried out manually. Manual analysis of NMR data results in high costs, lengthy an...

A fast chemical-shift imaging using the gradient-echo technique is proposed for the separation of the water and fat in human in vivo imaging. This technique also incorporates magnetic field inhomogeneity correction in the fast chemical-shift imaging. Experimental results of the proposed imaging technique demonstrate that the method would be useful for quick in vivo water-fat separation imaging ...

Frataxin is the protein responsible for the genetically-inherited neurodegenerative disease Friedreich's ataxia caused by partial silencing of the protein and loss of function. Although the frataxin function is not yet entirely clear, it has been associated to the machine that builds iron-sulfur clusters, essential prosthetic groups involved in several processes and is strongly conserved in org...

The reactions of isolable dialkylsilylene 1 with aromatic acyl chlorides afforded aroylsilanes 3a-3c exclusively. Aroylsilanes 3a-3c were characterized by ¹H-, 13C-, and 29Si-NMR spectroscopy, high-resolution mass spectrometry (HRMS), and single-crystal molecular structure analysis. The reaction mechanisms are discussed in comparison with related reaction of 1 with chloroalkanes and chlorosilanes.

Solvent evaporation upon drying the precipitate was found to be the key factor for the phase transformation of cubic mesoporous silica SBA-1 to hexagonal SBA-3 studied by in-situ X-ray diffraction and 29Si solid state NMR on the precipitates formed various crystallisation conditions.
