Wessjohann, L. A.; Schneider, A.; Kaluđerović, G. N.; Brandt, W.;Solid-phase synthesis of reduced selenocysteine tetrapeptides and their oxidized analogs containing selenenylsulfide eight-membered ringsMol. Divers.17537-545(2013)DOI: 10.1007/s11030-013-9454-x
A series of protected and reduced forms of model tetrapeptides that mimic the C-terminus of human thioredoxin reductases were obtained in good yields, using solid-phase peptide synthesis (SPPS). SPPS was performed on the Knorr Amide MBHA resin for Fmoc chemistry using especially protected cystein and selenocystein derivatives. All amino acids have been coupled according to the HBTU/HOBt/DIPEA method. Furthermore, the corresponding oxidized peptides containing eight-membered rings with intramolecular S–S and S–Se bridges were prepared via I2/MeOH or DMSO/TFA oxidation, respectively.
