Spin-label that has been used to study molecular migration and long-term stability of seeds and pollen. Has been covalently attached to oligonucleotides to prepare a DNA probe sensitive to electron spin resonance. The acetoxymethyl ester is an esterase-sensitive probe that crosses the blood-brain barrier for electron spin resonance-computed tomographic imaging.
Spin-label. The anionic form has been used to determine distribution coefficients of neutral solubilizates in anionic micelles.[1]
Used in the preparation of a tetraphenylporphyrin bearing a nitroxyl radical.[2]
Contrast agents have been investigated in an effort to increase the differences between the proton relaxation times of normal and pathologic tissue, and thus improve the ability to detect regions of pathology. Data on the oxygen-dependent metabolism of three nitroxides
The relations among hypertensive response, oxidative stress, and mitogen-activated protein kinase (MAPK) in cardiovascular tissues have not been fully established. We investigated the involvement of reactive oxygen species on changes in the hemodynamics and cardiovascular MAPKs activities induced by acutely

Proton-electron double-resonance imaging (PEDRI) has considerable value for study of the distribution and elimination pathways of nitroxide free radicals (NFRs). This has been illustrated by its use in studies of kidney function in the living rat in which the NFR

A simple expression is derived to compute the total Gaussian linewidth of a Voigt line that is broadened by sinusoidal magnetic-field modulation as follows: delta HPPG(Hm)2 = delta HPPG(0)2 + kappa 2Hm2, where delta HPPG(Hm) is the Gaussian linewidth observed

Clearance of the nitroxide radicals, hydroxy-TEMPO and carboxy-PROXYL, in whole-mouse lung was directly measured by in vivo ESR. After injecting a nitroxide radical, distribution of the nitroxide radical all over the lung was confirmed by ESR imaging. The ESR signal
