Estimation of water content and water mobility in the nucleus and cytoplasm of Xenopus laevis oocytes by NMR microscopy.
NMR microscopy is a noninvasive approach for studying cell structure and properties. Spatially resolved measurements of the relaxation times T1 and T2 provided information on the water proton spinExpand

Biosynthesis of rutacridone in cell cultures of Ruta graveleolens : incorporation studies with [13C] acetate
Carbon-13 labelling experiments have shown that ring C of the acridone alkaloid rutacridone is acetate-derived and that an aminobenzophenone derivative is a probable intermediate in the biosyntheticExpand

Mimicry of βII′‐turns of proteins in cyclic pentapeptides with one and without d‐amino acids
The solution structure of eight cyclic pentapeptides has been determined by two-dimensional 1H-NMR spectroscopy combined with spectra simulations and restrained molecular dynamic simulations. Six ofExpand

1H, 13C, 15N and 119Sn NMR investigations on stannatranes
Abstract 1H, 13C, 15N and 119Sn NMR data for alkyl- and phenyl-stannatranes are reported. A trimeric structure and an intramolecular dynamic process are proposed.

The structure of 5-aza-2,8-dioxa-1-stanna(II)bicyclo[3.3.0]octane
From the1H,13C, and119Sn NMR spectra at different temperatures, it is concluded that the 5-alkyl-5-aza-2,8-dioxa-1-stanna(II)bicyclo[3.3.0]octanes dimerize in nonpolar solvents. The barrier forExpand
