An Alternative Chelator for (89)Zr Radiopharmaceuticals

Zirconium89 is an effective radionuclide for antibodybased positron emission tomography (PET) imaging because its physical halflife (78.41 h) matches the biological halflife of IgG antibodies. Desferrioxamine (DFO) is currently the preferred chelator for (89)Zr(4+) however, accumulation of (89)Zr in the bones of mice

Review on Production of 89Zr in a Medical Cyclotron for PET

Jan 17, 2013 Unlike the commonly used 18FFDG, with a 109.7min halflife, the longer halflife of 89Zr makes it possible to use highresolution PET/CT to localize and image tumors with monoclonal antibody radiopharmaceuticals and thus potentially expand the use of PET. Methods: This paper briefly reviews the

Medicinal Chemistry of Radiopharmaceuticals PharmaFactz

Zirconium Radiopharmaceuticals. Zirconium89 (89Zr) is a positron emitter with a halflife of 78.4 hours (3.267 days) produced through proton irradiation of naturally occurring 89Y. There has been increased interest in positron emitters with longer halflives than 18F and 11C. 89Zr has potential appliions in immunoPET

Zirconium tetraazamacrocycle complexes display RSC Publishing

Dec 13, 2016 After evaluating several radioactive analogs, we found that 89Zr–DOTA is superior to 89Zr–DFO, the only 89Zrcomplex to be used clinically in 89Zrradiopharmaceutical appliions. Finally, we provide a rationale for the unanticipated and extraordinary stability of these complexes in vitro and in vivo.

A new technique for the radiolabelling of mixed leukocytes with

Apr 8, 2016 We have evaluated a new method for radiolabelling WBCs with either zirconium89 (89Zr) or copper64 (64Cu) for PET imaging. Chitosan nanoparticles (CNs) were produced by a process of ionotropic gelation and used to deliver radiometals into WBCs. Experiments were carried out using mixed WBCs
