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
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...
