  • Title: Synthesis and characterization of several carbamoyl- and methylcarbamoyl-substituted EMPO derivatives.
    Author: Stolze K, Rohr-Udilova N, Hofinger A, Rosenau T.
    Journal: Bioorg Med Chem; 2009 Nov 01; 17(21):7572-84. PubMed ID: 19800243.
    Abstract:
    The spin trapping behavior of four novel carbamoyl-substituted EMPO derivatives, namely 5-carbamoyl-3,5-dimethyl-pyrroline N-oxide (CADMPO), 3,5-dimethyl-5-methylcarbamoyl-pyrroline N-oxide (DMMCAPO), 5-carbamoyl-3-ethyl-5-methyl-pyrroline N-oxide (CAEMPO), and 3-ethyl-5-methyl-5-methylcarbamoyl-pyrroline N-oxide (EMMCAPO), towards different oxygen- and carbon-centered radicals is described, the half lives of the respective superoxide adducts ranging from about 10 to 20 min. The most characteristic adducts were, however, formed from methyl, hydroxymethyl, hydroxyethyl, and carbon dioxide anion radicals.
