Aplicación

5,5-Dimethyl-1-pyrroline N-oxide is a reagent generally used either as a free-radical spin-trapping agent, or electrophilic component during the synthesis of pyrrolidine derivatives. It may also be considered as 1,3-dipole in cycloaddition processes.
Neuroprotective agent; nitric oxide spin trap. Used to study radicals formed by enzymatic acetaldehyde oxidation. Incubation of lymphocytes with DMPO decreased DNA damage by NiCl2.

We compared oxygenation and anaerobic oxidation reactions of a purified complex of human hemoglobin (Hb) and haptoglobin (Hb-Hp) to those of uncomplexed Hb. Under equilibrium conditions, Hb-Hp exhibited active-site heterogeneity and noncooperative, high-affinity O(2) binding (n(1/2)=0.88, P(1/2)=0.33 mm Hg in

The detection of protein free radicals using the specific free radical reactivity of nitrone spin traps in conjunction with nitrone-antibody sensitivity and specificity greatly expands the utility of the spin trapping technique, which is no longer dependent on the quantum
