3-O-Methyl- d -glucose mutarotation and proton exchange rates assessed by 13 C, 1 H NMR and by chemical exchange saturation transfer and spin lock measurements
Abstract
3-O-Methyl-d-glucose (3OMG) was recently suggested as an agent to image tumors using chemical exchange saturation transfer (CEST) MRI. To characterize the properties of 3OMG in solution, the anomeric equilibrium and the mutarotation rates of 3OMG were studied by 1H and 13C NMR. This information is essential in designing the in vivo CEST experiments. At room temperature, the ratio...

Probing conformational dynamics in biomolecules via chemical exchange saturation transfer: a primer
Probing conformational dynamics in biomolecules via chemical exchange saturation transfer: a primer
Abstract
Although Chemical Exchange Saturation Transfer (CEST) type NMR experiments have been used to study chemical exchange processes in molecules since the early 1960s, there has been renewed interest in the past several years in using this approach to study biomolecular conformational dynamics. The methodology is particularly powerful for the study of sparsely populated, transiently formed conformers that are recalcitrant to investigation using...

[U. of Ottawa NMR Facility Blog] CEST - Chemical Exchange Saturation Transfer
CEST - Chemical Exchange Saturation Transfer
Chemical Exchange Saturation Transfer (CEST) is a technique where one resonance, in slow exchange with a second resonance, is saturated with a selective low power pulse followed by a hard non-selective 90° pulse. The intensity of the second resonance is then diminished due to the transfer of saturation from the first resonance as the result of chemical exchange. The figure below demonstrates this for a 25 mM solution of salicylic acid in H2O/D2O buffered at pH 7. ...
