Description

Biochem/physiol Actions

Inhibits induction of macrophage nitric oxide synthase.

Other Notes

Reagent used for the extraction of trace metals into organic solvents for atomic absorption spectroscopy; Precipitation of trace metals for x-ray fluorescence spectroscopy

Application

Spin trap used in conjunction with Fe2+ to detect NO in brain, kidney, liver, and other tissues. Simultaneous direct measurement of NO* and pO2 has been reported. A copper chelator, it has been used to quantitate copper in biological materials by ESR and is an inhibitor of superoxide dismutase, ascorbate oxidase, and other enzymes.
