PROCEDURE

实验过程

0.6 g of Fmoc-Pro-OH is dissolved in 100 ml of dichloromethane, 1.2 equivalents of Wang resin (p-benzyloxybenzyl alcohol resin) are added, and the mixture is stirred at room temperature for 12 hours. After removal of the solvent Fmoc-Pro-Wang resin is obtained. In a peptide synthesizer Fmoc-Cys(Trt)-OH is condensed with H-Pro-Wang resin [liberation from Fmoc-Pro-Wang resin using piperidine/DMF (20% strength)], using a three-fold excess of the protected cysteine. The coupling is carried out at room temperature in DCCI/HOBt, to give Fmoc-Cys(Trt)-Pro-Wang resin. Subsequent treatment with piperidine/DMF (20% strength) again gives H-Cys(Trt)-Pro-Wang resin.
