Hydroxamic acid-based bifunctional chelating compounds

摘要

The present disclosure details the preparation of hydroxamic-acid based bifunctional chelators and their use in conjugating metal ions to proteins and nucleic acids for tumor or tissue imaging or therapy purposes. Some preferred aspects of the disclosure involve the preparation of trisuccin, chemical name N-[tris(2-N- benzyloxyaminocarbonylethyl)] methylsuccinamic acid, which is a hydroxamic acid/succinate based structure that is particularly useful for binding radionuclides such as 99mTc, 186Re and 67Cu.
