Galactose oxidase models: insights from 19F NMR spectroscopy.
(19)F labelled tripodal ligands that possess a N(3)O donor set (one phenol, one tertiary amine and either two pyridines or one pyridine and one quinoline) have been synthesized. The fluorine is incorporated either at the phenol O-donor (HL(F) and HL(CF3)) or at the quinoline N-donor (HLq(OMe) and HLq(NO2)). The copper(ii)-phenol complexes (2H)(2+), (1H)(2+), (3H)(2+) and (4H)(2+) as well as the...
متن کاملMeasurement of cytosolic calcium using 19F NMR.
Fluorine-19 nuclear magnetic resonance (NMR) studies of cells and perfused organs loaded with fluorinated ion chelators represent a new approach to determining cytosolic free calcium levels in situ. The molecular basis for this approach and the relative advantages and disadvantages of the NMR technique are discussed in this paper. Results obtained on perfused normoxic and ischemic rat hearts ar...
متن کاملDynamics of the S1S2 glutamate binding domain of GluR2 measured using 19F NMR spectroscopy.
Ionotropic glutamate receptors mediate the majority of vertebrate excitatory synaptic transmission. Although the structure of the GluR2 binding domain (S1S2) is well known (agonist binding site between two lobes), little is known about the time scales of conformational transitions or the relationship between dynamics and function. (19)F NMR ((19)F-labeled tryptophan) spectroscopy was used to mo...
متن کاملApplication of 19F NMR Spectroscopy for Content Determination of Fluorinated Pharmaceuticals
A simple, rapid, and selective quantitative nuclear magnetic resonance spectroscopic method was evaluated for the determination of the content of fluorinated pharmaceuticals. 19F NMR spectra were either obtained in dimethylsulfoxide-d6 or aqueous buffer, using trifluoroacetic acid as internal standard. Quantification of 13 fluorine-containing pharmaceuticals spanning various pharmacological cla...
متن کامل1317 Detection of dexamethasone in the aqueous humour by 1H and 19F NMR spectroscopy
Background and purpose: A likely explanation for the increase in lens fluorescence with aging and the acceleration of this process in patients with diabetes, is that lens proteins are altered by non-enzymatic glycosylation and the further steps of the Maillard reaction. Thus, the lens fluorescence intensity appears to represent a cumulative index of glycemia over the entire lifetime of the subj...
