20090170134 | BIFUNCTIONAL AND TRIFUNCTIONAL NITRONE SPIN TRAPPING COMPOUNDS AND USES THEREOF - Methods and compositions for detecting free radicals, the compositions being spin trapping compounds comprising a nitrone having a detecting moiety and optionally having a targeting moiety for targeting the nitrone to an organ, a cell, an organelle or a molecule of interest for directly detecting free radicals, especially free radicals in biological samples. | 07-02-2009 |
20100249386 | DINITROXIDE-TYPE BIRADICAL COMPOUNDS OPTIMIZED FOR DYNAMIC NUCLEAR POLARIZATION (DNP) - The present invention relates to the field of organic chemistry and in particular to organic free radicals used as polarizing agents in the technique of Dynamic Nuclear Polarization (DNP), which involves transferring the polarization of electron spins to the nuclei of a compound whose Nuclear Magnetic Resonance (NMR) is being observed. It concerns dinitroxide-type biradical polarizing agents characterized by a rigid linkage between the nitroxide units that enables optimal orientation and distance to be maintained between the aminoxyl groups of said nitroxide units. This particular structure enables, at low temperatures and high fields, optimal transfer of polarization and optimal enhancement of NMR/MAS signals of the polarized nuclei of the compound studied. | 09-30-2010 |
