    摘要: A stabilized radiopharmaceutical composition, a kit including same, and a method for making same, where the radiopharmaceutical is (i) susceptible to either reductive degradation or radiolysis and which includes a metal complex of a radionuclide with a ligand, (ii) a first stabilizer for the radiopharmaceutical which is an amino-substituted aromatic carboxylic acid or a salt, ester or amide thereof, and (iii) a second stabilizer for the radiopharmaceutical which is a diphosphonic acid or salt thereof. The first and second stabilizers are present in an amount effective to stabilize the radiopharmaceutical, and the radiopharmaceutical is not a metal complex of the diphosphonic acid.

    摘要: 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.

    摘要: A peptide having affinity with inflammation is disclosed, which contains at least one of the following amino acid sequences: LLGGPS (SEQ ID NO:1), LLGGPSV (SEQ ID NO:2), KEYKAKVSNKALPAPIEKTISK (SEQ ID NO:3), KEYKCKVSNKALPAPIEKTISK (SEQ ID NO:4), KTKPREQQYNSTYR (SEQ ID NO:5), and KTKPREQQYNSTYRVV (SEQ ID NO:6), wherein A, C, E, G, I, K, L, N, P, Q, R, S, T, V, and Y represent amino acid residues expressed by standard one-letter symbols. According to the present invention, a peptide and its chemically modified substances, radioactive metal labeled peptides derived therefrom, and radioactive diagnostics comprising such peptide are provided, which are useful for imaging inflammation region and easy in preparation handling, and accumulate at inflammation site immediately after administration while being excellent in clearance into urine. The imaging is possible in several ten minutes after administration.
