[15N]Nitric oxide (15NO) was produced in a “gas-tight” flask from [15N]nitrite by reaction with iodide in acetic acid acidified water and purged for 60 min by a continuous nitrogen gas stream applied through an uncoated polytetrafluoroethylene flate membrane into a second flask which contained a methanolic solution of N-acetyl-L-cysteine or N-acetyl-DL-penicillamine. Analysis of these solutions by UV spectroscopy, reversed-phase high-performance liquid chromatography and capillary isotachophoresis showed formation of the corresponding S-nitroso compounds. Gas chromatographic-mass spectrometric analysis for [15N]nitrite which was formed by dissolving these compounds in aqueous buffered solutions gave an isotopic purity higher than 95% at 15N. The S-nitroso compounds were shown to inhibit ADP-induced platelet aggregation.
