The plasma clearance and the liver uptake of intravenously administered (64)Cu were significantly impaired in four patients with Wilson's disease. These defects were unlikely to be simply expressions of the high liver copper concentration as the plasma clearance and hepatic uptake of (64)Cu were normal in four patients with primary biliary cirrhosis, in whom the liver copper concentration was r...

Ceruloplasmin, the main copper binding protein in blood plasma, has been of particular interest for its role in efflux of iron from cells, but has additional functions. Here we tested the hypothesis that it releases its copper for cell uptake by interacting with a cell surface reductase and transporters, producing apoceruloplasmin. Uptake and transepithelial transport of copper from ceruloplasm...

Copper-64 was produced in large scales and high specific activities in late 1990s’ using compact cyclotrons based by 64Ni(p,n)64Cu reaction and many radiopharmaceuticals developed since then by various groups based on interesting physicochemical and nuclear properties of the radionuclide. The unique emission of beta particles as well as positron particles offers a spectacu...

The title compound, C(14)H(17)N(5)O, a 1,2,3-triazole derivative of benzoxadiazole (C(14)H(17)N(5)O), was synthesized via Cu-catal-ysed azide-alkyne cyclo-addition (CuAAC) from the corres-ponding n-octyne and 4-azido-benzoxadiazole. The benz-oxa-diazole and triazole rings show a roughly planar orientation [dihedral angle between the ring planes = 12.18 (5)°]. The alkane chain adopts a zigzag co...

In the title compound, [Cu(C(7)H(4)FO(2))(2)(C(12)H(8)N(2))(H(2)O)], the coordination around the Cu(II) atom is square-pyramidal. The equatorial positions are occupied by two N atoms from a 1,10-phenanthroline ligand [Cu-N = 2.008 (3) and 2.019 (3) Å] and two O atoms from 3-fluoro-benzoate ligands and a water mol-ecule [Cu-O = 1.950 (2) and 1.978 (2) Å]. One O atom from another 3-fluoro-benzoat...

In the title complex, [Cu(C(14)H(13)N(3)O)(C(14)H(12)N(3)O)](CCl(3)COO), the central Cu(II) ion exhibits a distorted octa-hedral geometry with the two ligands coordinating in an meridional format. The N(4)O(2) ligand environment is defined by two benzoyl O atoms, two pyridyl N atoms and imino N atoms. As evidenced by the bond lengths, the two benzohydrazone ligands exist in distinctively differ...

Dicopper species have been identified as the active sites in converting methane to methanol in Cu-zeolites. To understand the formation of these copper cores in mordenite, we used in situ time-resolved X-ray absorption spectroscopy during heat treatment. Significant dehydration enabled the reduction of the copper cores, after which molecular oxygen was cleaved. The activated oxygen bridged two ...
