PROTEIN- AND PEPTIDE-METAL ION PHARMACEUTICAL APPLICATIONS

摘要

Peptides containing a biological-function domain and a medically useful metal ion-binding domain and proteins containing monosulfide or disulfide bonds are labeled with medically useful metal ions for use in diagnosis and treatment of a variety of pathologic conditions. The peptides have the amino acid sequence (R1)-[Y1]n-(R2), (R1)-[Y1-(R2)-Y1]n-(R3), and (R1)-[Y1-(R2)-Y2]n-(R3), with the biological-function domain optionally containing the sequence IKVAV and YIGSR. The medically useful metal ion-binding domain is [Y1]n, [Y1-(R2)-Y1]n or [Y1-(R2)-Y2]n. Sn(II) agents are used to label the proteins with medically useful metal ions.
