Abstract:
Provided is a cyclic peptide, which is represented by Formula (I) or Formula (I′) and has excellent antibody binding properties and improved chemical resistance, an affinity chromatography support, a labeled antibody, an antibody drug conjugate, and a pharmaceutical preparation. R N -X g -[X i -X a -X m -X 2 -X 3 -X n -X b -X j ] k -X h -R C   (I) In Formula (I), X a  and X b  each independently represent an amino acid residue derived from an amino acid, other than L-cysteine and D-cysteine, having a thiol group on a side chain and are bonded to each other through a disulfide bond, or, one of X a  and X b  represents an amino acid residue derived from an amino acid, other than L-cysteine and D-cysteine, having a thiol group on a side chain and the other represents an amino acid residue derived from an amino acid having a haloacetyl group on a side chain, and X a  and X b  are bonded to each other through a thioether bond. R N -X g -[X i -X a -X m -X 1 -X 2 -X 3 -X n -X b -X j ] k -X h -R C   (I′) In Formula (I′), one of X a  and X b  represents an amino acid residue derived from L-cysteine or D-cysteine and the other represents an amino acid residue derived from an amino acid having a haloacetyl group on a side chain, and X a  and X b  are bonded to each other through a thioether bond, or, one of X a  and X b  represents an amino acid residue derived from L-penicillamine or D-penicillamine and the other represents an amino acid residue derived from an amino acid having a haloacetyl group on a side chain, and X a  and X b  are bonded to each other through a thioether bond.
