Conjugates of biotin and deferoxamine for radioimmunoimaging and radioimmunotherapy

摘要

The present invention provides compounds which are covalent conjugates of deferoxamine and biotin or derivatives thereof. The subject compounds are capable of binding metal ions and avidin or streptavidin, and accordingly are useful in two-step radioimmunoimaging and radioimmunotherapy. Methods for the synthesis of the deferoxamine-biotin conjugates are also provided by the present invention.
