Abstract: The present invention relates to a compound of the formula These modified streptavidin compounds have are useful as part of a delivery system to deliver a molecule to a target site for use in diagnosis or therapy.

Abstract: The present invention provides modified avidin and streptavidin compounds that have suitable blood clearance kinetics for use in a two-step approach to deliver a molecule to a target site. In particular, to hasten SA's blood clearance carbohydrate moieties are covalently bonded to SA. To prolong Avid's blood clearance, Avid is deglycosylated and/or neutralized by alkylation of its lysine amino acids. In a two-step approach, biotinylated compounds are used to deliver radionuclides, cytotoxic drugs, MRI agents, fluorochromes and other agents suitable for imaging and therapy to target-bound modified streptavidin or avidin conjugated antibodies or other targeting agents.

Abstract: The present invention provides biotinylated compounds useful for delivering a molecule to a target site, and methods of making biotinylated compounds. The biotinylated compounds are covalent conjugates of biotin and a diagnostic or therapeutic agent, and are stable to rapid degradation by biotinidase. The compounds of the invention are useful for delivering therapeutic or diagnostic agents to target-bound streptavidin or avidin conjugated cell-targeting agents, including monoclonal antibodies. The compound N-cysteinyl biotin is also provided.

Abstract: 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.
