Description générale

S-Nitrosoglutathione (GSNO) is an endogenous nitrogen oxide and is highly distributed in extracellular fluids of the lung and brain.

Application

S-Nitrosoglutathione (GSNO) has been used:
  • as a standard in reversed phase chromatography coupled to chemical vapour generation and atomic fluorescence detector (RPC-CVGAFS) and reversed phase chromatography fluorimetric (RPC-FD).
  • as a standard in spectrophotometric and high-performance liquid chromatography (HPLC) assay.

Actions biochimiques/physiologiques

S-Nitrosoglutathione (GSNO) inhibits the activity of sarcoplasmic reticulum-bound creatine kinase in rabbit skeletal muscle and eventually reduces ATP driven Ca2+ uptake in sarcoplasmic reticulum vesicles. GSNO in airway cells relaxes airway smooth muscle and enhances airway ciliary motility. It also blocks airway epithelial amiloride-sensitive sodium transport while stimulating calcium-dependent epithelial chloride transport and induces neutrophilic apoptosis. In addition, it also has antimicrobial activity. GSNO concentration is low in cystic fibrosis (CF) airway. It is an NO donor, acts as a smooth muscle relaxant, vasodilator and inhibits platelet activation in vivo.

Recent results demonstrated that S-nitrosoglutathione (GSNO) and nitric oxide (*NO) protect brain dopamine neurons from hydroxyl radical (*OH)-induced oxidative stress in vivo because they are potent antioxidants. GSNO and *NO terminate oxidant stress in the brain by (i) inhibiting iron-stimulated

Genetic and biochemical data demonstrate a pivotal role for S-nitrosothiols (SNOs) in mediating the actions of nitric oxide synthases (NOSs). SNOs serve to convey NO bioactivity and to regulate protein function. This understanding is of immediate interest to the pulmonary
