実験手順

Typical preparations of S-nitrosocaptopril involve the reaction of 50 mM captopril with 50 mM NaNO2 in 0.1 N acetic or sulfuric acid at room temperature for five minutes, after which the reaction solution is passed over a cation exchange resin, e.g., Dowex 50 in the protonated form, and the product eluted with water. The fractions that give positive reactions with N-(1-naphthyl)ethylenediamine, after exposure to 0.15% HgCl2 and diazotization with sulfanilamide, are lyophilized. Hygroscopic, bright red crystals were obtained that were
