| CARBOXY-PTIO Usage And Synthesis |
| Description | A nitric oxide (NO) scavenger.? Carboxy-PTIO (148819-94-7) reacts with NO with 1:1 stoichiometry1 producing NO2–/NO3–.?? In LPS-induced endotoxin shock, carboxy-PTIO reversed hypotension and renal dysfunction and increased survival in a rat model.2 A very useful tool for probing the involvement of NO in physiological processes.3,4 | | Chemical Properties | blue powder | | Uses | A water soluble, stable organic free radical that reacts stoichiometrically with NO. Carboxy-PTIO converts NO to NO2 and does not dramatically affect other NO related metabolites. This scavenger allows for the specific investigation of the effect of NO. | | Uses | Carboxy-PTIO is a NO scavenger. It reacts stoichiometrically with NO and can be used for EPR detection of NO. | | Uses | Carboxy-PTIO potassium salt has been used to check the generation of hydroxyl radicals or nitric in reaction mixtures to examine the generation of nitric oxide in reaction mixture. It has also been added to neurons to analyse its effect on glucose/oxygen/serum deprivation (GOSD) condition(4) | | General Description | 2-(4-Carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide?(carboxy-PTIO) is mainly considered as a scavenger of nitric oxide?(NO). | | Biological Activity | A stable, water-soluble free radical that reacts stoichiometrically with NO. Almost twice as strong an inhibitor as N( ω )-nitroarginine or N-methylarginine. | | Biochem/physiol Actions | Carboxy-PTIO can make a quick reaction with nitric oxide?(NO) to produce nitrogen dioxide (NO2). It can be used to prevent hypotension and endotoxic shock, stimulated by lipopolysaccharide in- vivo. Carboxy-PTIO can also block in vitro vascular relaxation, stimulated by NO. | | References | Akaike et al.
