実験手順

Glutathione (N—(N—L—γ-glutamyl-L-cysteinyl)glycine) (100 g, 0.325 mol) was dissolved in deoxygenated water (200 ml) and 2N HCl (162 ml) at room temperature and then the reaction mixture was cooled to 0° C. With rapid stirring, a solution of sodium nitrite (24.4 g, 0.35 mol) in water (40 ml) was added. Stirring with cooling of the reaction mixture was continued for approximately 1 hour, after which time the pink precipitate which formed was collected by vacuum filtration. The filter cake was resuspended in chilled 40% acetone-water (600 ml) and collected by vacuum filtration. The filter cake was washed with acetone (2×200 ml) and ether (100 ml) and then dried under high vacuum at room temperature in the dark to afford the title compound, N—(N—L—γ-glutamyl-S-Nitroso-L-cysteinyl)glycine, as a pink powder. 1H NMR (D2O): δ1.98 (m, 2H), 2.32 (t, 2H), 3.67 (t, 1H), 3.82 (s, 2H), 3.86 (dd, 1H), 3.98 (dd, 1H), 4.53 (m, 1H).
