ABSTRACT:
The present invention provides peptides represented by the following formula (A):wherein Q represents a physiologically active peptide moiety; X each represents the same or different α-amino acid residue; M represents Gly or Cys; m represents an integer of from 5 to 8; and n represents an integer of from 0 to 3, or their pharmaceutically acceptable salts thereof.The peptides of the present invention have higher stability and/or higher activity than physiologically active linear peptides to which no cyclic peptide is bonded.
