A ligand of Formula (I) is provided: wherein A4 represents a hydrogen atom, a nitro group, an amino group, a thiocyanato group, or —Z—Y, in which Z is a divalent linking group and Y is a group derived from a biocompatible molecule, with the proviso that when X is methylene, A4 cannot be a hydrogen atom or a nitro group. A metal complex having the ligand is also provided and is useful as a blood pool contrast agent or a targeting contrast agent.

A new bifunctional chelating agent (BCA), 3-(4-isothiocyanatobenzyl) triethylenetetraaminehexaacetic acid (9), has been synthesized in fast and easy conditions. An improved synthesis of its position isomer 1-(4- isothiocyanatobenzyl)triethylenetetraaminehexaacetic acid (19) is also described. Stability in serum media of the two corresponding aminobenzyl derivatives-samarium-153 complexes, respectively, 3-(4-aminobenzyl) triethylenetetraaminehexaacetic acid-samarium-153 and 1-(4-aminobenzyl) triethylenetetraaminehexaacetic acid-samarium-153, have been evaluated. The 3-(4-aminobenzyl)triethylenetetraaminehexaacetic acid complex revealed excellent stability in serum media, and therefore 3-(4-isothiocyanatobenzyl) triethylenetetraaminehexaacetic acid (9) appears useful for future in vivo radioimmunotherapy investigations.
