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.
