Application

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.

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.

Protein thiyl radical mediates S-glutathionylation of complex I.

Patrick T Kang et al.

Free radical biology & medicine, 53(4), 962-973 (2012-05-29)

Complex I is a critical site of O(2)(•-) production and the major host of reactive protein thiols in mitochondria. In response to oxidative stress, complex I protein thiols at the 51- and 75-kDa subunits are reversibly S-glutathionylated. The mechanism of

Detection and imaging of the free radical DNA in cells--site-specific radical formation induced by Fenton chemistry and its repair in cellular DNA as seen by electron spin resonance, immuno-spin trapping and confocal microscopy.

Suchandra Bhattacharjee et al.

Nucleic acids research, 40(12), 5477-5486 (2012-03-06)

Oxidative stress-related damage to the DNA macromolecule produces lesions that are implicated in various diseases. To understand damage to DNA, it is important to study the free radical reactions causing the damage. Measurement of DNA damage has been a matter

Using anti-5,5-dimethyl-1-pyrroline N-oxide (anti-DMPO) to detect protein radicals in time and space with immuno-spin trapping.

Ronald P Mason

Free radical biology & medicine, 36(10), 1214-1223 (2004-04-28)

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

Theoretical and experimental studies of the spin trapping of inorganic radicals by 5,5-dimethyl-1-pyrroline N-oxide (DMPO). 3. Sulfur dioxide, sulfite, and sulfate radical anions.

Pedro L Zamora et al.

The journal of physical chemistry. A, 116(26), 7210-7218 (2012-06-07)

Radical forms of sulfur dioxide (SO(2)), sulfite (SO(3)(2-)), sulfate (SO(4)(2-)), and their conjugate acids are known to be generated in vivo through various chemical and biochemical pathways. Oxides of sulfur are environmentally pervasive compounds and are associated with a number

Kinetic analysis of reactive oxygen species generated by the in vitro reconstituted NADPH oxidase and xanthine oxidase systems.

Emiko Sato et al.

Journal of biochemistry, 150(2), 173-181 (2011-05-17)

The nicotinamide adenine dinucleotide (NADH)/nicotinamide adenine dinucleotide phosphate (NADPH) oxidase and the xanthine oxidase (XOD) systems generate reactive oxygen species (ROS). In the present study, to characterize the difference between the two systems, the kinetics of ROS generated by both
