Synthesis of N-[tris[2-[[N-(benzyloxy)amino]carbonyl]ethyl]methyl]succinamic acid, trisuccin. Hydroxamic acid derivatives as a new class of bifunctional chelating agents.

In an effort to generate bifunctional chelating agents (BCAs) with improved labeling, conjugation, and biodistribution properties, the synthesis of trisuccin is reported. This new hydroxamate BCA, after synthesis and characterization, was used for conjugation and radiolabeling of monoclonal antibodies with 99mTc. This new class of synthetic BCAs may be useful in the radioimmunodiagnosis and radioimmunotherapy of cancer.
