摘要:
Methods, compounds, compositions and kits that relate to pretargeted delivery of diagnostic and therapeutic agents are disclosed. In particular, methods for radiometal labeling of biotin and for improved radiohalogenation of biotin, as well as related compounds, are described. Also, clearing agents, anti-ligand-targeting moiety conjugates, target cell retention enhancing moieties and additional methods are discussed.
摘要:
Novel chelating compounds and the corresponding radionuclide metal chelates are useful for radiolabeling proteins such as antibodies, ligands such as biotin and anti-ligands such as streptavidin with radionuclide metals such as ?99mTc, 186¿Re, and 188Re. The radiolabeled proteins, ligands and anti-ligands have diagnostic or therapeutic use, depending on the radionuclide metal chosen.
摘要:
Polymeric carriers are polypeptides comprising at least one drug-binding domain that non-covalently binds a drug. A polymeric carrier may be attached to an antibody specific for desired target cells to form immunoconjugates that deliver a drug to the target cells in vivo. A polymeric carrier may be attached to a proteinaceous or a non-proteinaceous ligand or anti-ligand to form a conjugate useful in pretargeting protocols to deliver a drug to target cells in vivo. The carriers are derived from drug-binding proteins and produced through peptide synthesis or recombinant DNA technology.
摘要:
The present invention provides methods for directing the biodistribution of molecules that are not generally specifically excreted via the renal pathway to renal excretion. The methods employ conjugates or complexes containing a directed biodistribution molecule (DBM) and one or more bound molecules, wherein the biodistribution of the conjugate or complex is directed to renal excretion in vivo by the DBM component thereof.

摘要:
Chelating compounds of specified structure are useful for radiolabeling targeting proteins such as antibodies as well as proteinaceous and non-proteinaceous ligands and anti-ligands. The radiolabeled antibodies, ligands or anti-ligands, or catabolites thereof, demonstrate improved biodistribution properties, including reduced localization within the intestines.
