Reaction Conditions

Reaction Steps

1.53 g (5 mmol) L-glutathione (GSH) was dissolved in a mixture of 5.5 ml water and 2.5 ml (2 N) aqueous HCl solution cooled in ice bath, then 0.345 g (mmol) sodium nitrite was added. The mixture was stirred for 40 min at 5° C., then 10 ml acetone was added and the solution was stirred for further 10 min. The precipitated brown deposit was filtered and subsequently washed with ice-cold water (5×1 ml), acetone (3×10 ml) and ether (3×10 ml). Thus 1.29 g (3.8 mmol) of S-nitrosoglutathione was obtained (76% yield).
