Comparative study of electrochemical redox behaviour of five different nitroxyl radicals leads to the direct correlation between one-electron redox potentials and group electronegativity of the beta-substituent on the ring. Beta-substituents with an electron-donating effect caused a negative shift in the one-electron oxidation and one-electron reduction(More)
In vivo redox reactions of nitroxyl contrast agents in bile and blood under an oxidative atmosphere were investigated using normal healthy Wistar rats. Differences in intracellular and extracellular volumes in redox environments are discussed. Pharmacokinetic profiles of two nitroxyl contrast agents, 3-carbamoyl-2,2,5,5-tetramethylpyrrolidine-N-oxyl(More)
Effect of amifostine, a radiation-protecting drug, on muscle tissue partial pressure of oxygen was investigated by electron paramagnetic resonance spectroscopy and imaging. When amifostine was administered intraperitoneally or intravenously to mice, the linewidth of the electron paramagnetic resonance spectra of the lithium octa-n-butoxy-substituted(More)
