The invention relates to the use of metal tricarbonyl compounds of the general formula [M(CO),L,]′, wherein M is rhenium or technetium or an isotope thereof and L is a ligand, for the preparation of a medicament for the treatment of cancer that is both radiotherapeutic and chemotoxic when a radioactive metal is used and chemotoxic when cold rhenium or macroscopic amounts of long-lived Tc-99 is used. The medicament is in particular chemotoxic by causing intrastrand linkages in DNA. In a specific embodiment at least one of L is not OH2. The invention further relates to novel compounds of the general formula IM(CO)3XIX2X3]+ and their use, wherein M is rhenium or technetium or an isotope thereof and at least one X1. X2 and X3 is a monodentate ligand; or two of X, X2 and X3 are part of a bidentate ligand and the other one is optionally a monodentate ligand.

摘要:
The present invention is directed towards classifying tumor biomarkers, particularly membrane receptors, and more particularly the gastrin-releasing peptide (GPR) receptors, identified in patient samples, then linking therapeutic agents (chemical, radiological, or biological) to patient-specific ligands that bind to such receptors, clinicians can produce diagnostic and treatment compositions and implement treatment regimens which, by using the classified and identified biomarkers, and due to their improved accuracy, increase success and decrease undesired side effects from such treatments.

N-substituted 3-hydroxy-4-pyridinones and metal chelates, methods of preparing N-substituted 3-hydroxy-4-pyridinones and metal chelates, and pharmaceutical compositions containing new N-substituted 3-hydroxy-4-pyridinones and/or their metal chelates. Use of N-substituted 3-hydroxy-4-pyridinones and their metal chelates as pharmaceutical agents for the treatment of diseases, such as parasitic and viral infections, conditions associated with inflammation and infection, and conditions mediated by cell-proliferation or collagen formation.
摘要:
The present invention relates to an apparatus and method for administering a radioactive tracer dye and an inhibitor compound into a breast duct of the breast and imaging the breast for breast lesions. The radioactive tracer dye may be Tc-99m sestamibi and the inhibitor compound may inhibit a P-glycoprotein pump in tumor cells. When the inhibitor compound inhibits the P-glycoprotein pump in tumor cells, the radioactive tracer dye may effectively accumulate in tumor cells and improve the sensitivity of nuclear imaging of breast lesions.
摘要:
The present invention relates to a method of preparing technetium or rhenium complex for radiopharmaceuticals, through reaction of pertechnetate or perrhenate with a ligand in the presence of a reducing agent, wherein the reducing agent is a borohydride exchange resin (BER) . The borohydride exchange resin of the present invention has advantages of being stable in a wide range of Ph, including acidic or alkaline condition(Ph 2null14) and thus being applicable to biological materials as well as being easily removable through filtration when being administrated. Also since the radiolabelled complex is produced under conditions milder than those required for the conventional reducing agents as well as has high radiochemical purity and high labeling efficiency, the conventional reducing agents can be replaced by the BER of the present invention.

The present invention relates to a new method for the preparation of radiopharmaceuticals based on technetium and rhenium. The method involves the reaction of a salt of the formula nullM(CO)3(Xm)3null(1null3m), wherein M is selected from a radioisotope of rhenium, technetium and any other radioisotope that binds in a similar fashion, X is any suitable ligand and m is the formal charge for ligand X, with a nido-dicarbollide dianion of the formula nullnido-(C2B9H11)null2null and functional derivatives thereof. The method has been shown to be applicable to the preparation of radiopharmaceuticals at the tracer level.
