  • The Effect of Structure on Nitroxide EPR Spectral Linewidth

    Nitroxides with narrow linewidths are essential for low-frequency EPR spectroscopy and in vivo EPR imaging. In developing a framework for designing narrow-line nitroxides, we sought to understand the unexpectedly narrow line width of 4-oxo-2,2,6,6-tetramethyl-1-piperidinyloxyl (5). Computational modeling revealed that the carbonyl double bond in the 4-position allows conformational diversity that results in the observed narrowing of the EPR spectral line. In view of this finding, we synthesized two new nitroxides bearing an exocyclic double bond: 4-methoxycarbonylmethylidene-2,2,6,6-tetramethyl-1-piperidinyloxyl (7) and 4-acetoxymethoxycarbonylmethylidene-2,2,6,6-tetramethyl-1-piperidinyloxyl (9). These nitroxides, like nitroxide 5, exhibited narrow linewidths-consistent with the results of modeling. Nitroxide 8 (4-carboxymethylidene-2,2,6,6-tetramethyl-1-piperidinyloxyl), as a prototype, allows for a variety of structural diversity, such as nitroxide 9,that can, for instance, target tissue compartments for in vivo EPR imaging.
