実験手順
A solution of 1-(5-amino-2-mercaptomethylpentanoyl)-L-proline (2.3 g), guanyl-3,5-dimethylpyrazole nitrate (2.41 ) and triethylamine (3.36 ml) in dimethylformamide (20 ml) is stored at room temperature under a blanket of argon for sixteen hours. The solvents are removed in vacuo, the residue is dissolved in 0.1 N hydrochloric acid (10 ml) and zinc dust (500 mg) is added. The suspension is stirred at room temperature for two hours. After filtering, the filtrate is applied to a column of Dowex 50 ion exchange resin in the hydrogen cycle. The column is washed with water until no more acid is eluted and 1-(5-guanidino-2-mercaptomethylpentanoyl)-L-proline is then eluted with a pyridine-acetate buffer at pH 6.5.
