Introduction: 64Cu-pyruvaldehyde-bis(N4-methylthiosemicarbazone) (64Cu-PTSM) is one of the most important copper radiopharmaceuticals used in clinical experiments. Methods: In this work, copper-64 (T1/2=12.33 h) production has been presented followed by the synthesis of the complexing agent, PTSM, and its structure was confirmed by common spectroscopic methods followed by radiolabeling w...
UNLABELLED Tumor uptake of copper(II)-diacetyl-bis(N(4)-methylthiosemicarbazone) (copper-ATSM), a hypoxia-targeting radiopharmaceutical, assessed by PET has been found to correlate with prognosis in several human cancers. Wide clinical utility of this tracer will require its labeling with a copper radionuclide having a longer half-life than the (60)Cu used in studies to date. The purpose of thi...
The delivery of copper to mammary gland and milk and the effects of lactation were examined in rats. Traces of (67)Cu/(64)Cu(II) were injected intraperitoneally or intravenously into virgin rats or lactating rats (2-5 days postpartum), and incorporation into blood, milk, and tissues was monitored. In virgin rats, most of the isotope first entered the liver and kidney. In lactating rats, almost ...
UNLABELLED Alzheimer disease (AD) is a fatal neurodegenerative disorder characterized by progressive neuronal loss and cognitive decline. The lack of reliable and objective diagnostic markers for AD hampers early disease detection and treatment. Growing evidence supports the existence of a dysregulation in brain copper trafficking in AD. The aim of this study was to investigate brain copper tra...
