19F NMR techniques were employed to characterize the binding property of the widely used general anesthetic halothane with human serum albumin (HSA). It was found that 19F(1H) NOE and 2D 1H-19F HOESY experiments detected intermolecular NOEs between halothane 19F and HSA protons. Measurements of the diffusion coefficients for halothane were also carried out by 1H and 19F NMR, indicating the interaction of halothane with HSA. The present results indicate that these techniques are very suitable to identify a fluorine-containing ligand binding with a protein receptor in the drug-discovery process.

New lines of evidence suggest that volatile anesthetics interact specifically with proteins. Direct binding analysis, however, has been largely limited to soluble proteins. In this study, specific interaction was investigated between isoflurane, a clinically important volatile anesthetic, and...

Simultaneous detection of amide and methyl correlations using a time shared NMR experiment: application to binding epitope mapping

Journal of Biomolecular NMR; 2007; 39(2) pp 97 - 105
Abstract:
Simultaneous recording of different NMR parameters is an efficient way to reduce the overall experimental time and speed up structural studies of biological macromolecules. This can especially be beneficial in the case of fast NMR-based drug screening applications or for collecting NOE restraints, where prohibitively long data collection...
