摘要:Compositions and methods for dual imaging and for dual chemotherapy and radiotherapy are disclosed. More particularly, the invention concerns compounds comprising the structure X 1 —Y—X 2 , wherein Y comprises two or more carbohydrate residues covalently attached to one another, X 1 and X 2 are diagnostic or therapeutic moieties covalently attached to Y, provided that when Y does not comprise a glucosamine residue, X 1 and X 2 are diagnostic moieties. The present invention also concerns methods of synthesis of these compounds, application of such compounds for dual imaging and treatment of hyperproliferative disease, and kits for preparing a radiolabeled therapeutic or diagnostic compound.

标题 :Method of preparing rhenium complex using borohydride exchange resin

摘要:Disclosed is a method of preparing a rhenium complex by use of a borohydride exchange resin, including dissolving perrhenic acid in a solution containing ethylenediamine tetraacetate, mannitol and stannous chloride to obtain a perrhenic acid solution (step 1), which is then mixed with disulfide in the presence of a borohydride exchange resin and reacts at room temperature, to obtain a rhenium complex (step 2). The preparation method of the current invention is characterized in that rhenium is reduced to have a desired oxidation number through the dissolving of the step 1, whereby the reaction of the step 2 can occur at room temperature. In addition, use of the borohydride exchange resin as a reducing agent results in direct formation of the rhenium complex of sulfide from disulfide, without the need of synthesis of thiol-protected S-precursor. Therefore, radioactive pharmaceuticals having high values can be economically and efficiently produced.

摘要:Conjugate molecules comprising a ligand bonded to a polymer are disclosed. One such conjugate molecule comprises a ligand bonded to a polymer, a chelating agent bonded to the polymer, and a radioisotope chelated to the chelating agent. The conjugate molecules may be useful in detecting and/or treating tumors or biological receptors. These conjugate molecules may be synthesized without the necessity of preactivation of the ligand using an SCN-polymer-chelating agent precursor. Conjugate molecules incorporating an annexin V ligand are particularly useful for visualizing apoptotic cells. Conjugate molecules incorporating a C225 ligand are particularly useful for targeting tumors expressing EGFR.
