| Application: |
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) |
| 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. |
| Biochem/physiol Actions: |
Reacts with nitric oxide to form carboxy-PTI derivatives which in turn inhibits nitric oxide synthase. |
| 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). |
