摘要 |
<p>The invention provides a metal chelate forming peptide having an amino acid sequence of three amino acid residues represented by: X1-X2-Cys, wherein X1 represents an amino acid residue other than Cys residue; X2 represents an amino acid residue other than Cys residue and Pro residue; functional groups at the N-terminus, C-terminus and side chain may be substituted with protecting groups; and each of the amino acid residues may be any of D-form and L-form. Further, the invention provides a complex of the peptide with a physiologically active peptide, protein or other substance; a labeled reagent obtained by labeling the peptide or the complex with a metal radionuclide; and a radiodiagnostic and radiotherapeutic composition comprising the metal radionuclide-labeled reagent.</p> |
