The peptides\u00B4 ring was realized by azo-bond formed between N-atoms in the side chains of the amino acids. For MALDI-TOF MS experiments, two matrices CHCA and DHB were used. In the case of CHCA, only the peaks of cyclic peptides were observed in spectra. On the other hand, using DHB, additional, 4 Dalton heavier peak appeared, which most probably represents a linear form of the peptide with reduced azo-bond."@en .
