A rapid and efficient microwave irradiation solid-phase synthesis method was developed for the preparation of the reduced form of oxytocin and lysipressin on Rink amide-MBHA resin by an Fmoc/t-Bu orthogonal protection strategy. The disulfide bridge of the target peptide was formed directly on resin under microwave irradiation or normal condition. The crude products of peptides were cleaved from the resin by treatment with Reagent K. The HPLC analysis showed that the purity of the crude cyclopeptide was higher under microwave irradiation than under normal condition. The crude peptides were purified by preparative RP-HPLC. The molecular weight of the synthetic peptides was confirmed by the electrospray mass spectrometry analysis.

Key words: microwave irradiation, disulfide bridge, solid phase peptide synthesis, cyclopeptide
