HNO has broad biological effects and pharmacological activities. Direct HNO probes for in vivo applications were recently reported, which are CuII-based complexes having fluorescence reporters with reaction to HNO resulting in CuI systems and the release of NO. Their coordination environments are similar to that in Cu,Zn-superoxide dismutase (SOD), which plays a significant role in cellular HNO...

The title compound, [Cu(NO3)(C12H8N2)2]NO3·C7H6O5·H2O, consists of a mononuclear complex cation with the central CuII atom in a distorted trigonal-bipyramidal coordination sphere. Two N atoms of two 1,10-phenanthroline ligands occupy the axial sites, and the remaining N atoms of the two ligands, as well as one nitrate O atom the equatorial positions. One mol-ecule each of gallic acid and water ...

The quinquedentate macrocyclic ligand cyclo-6,6'-[1,9-(2,5,8-trithianonane)]-2,2'-bipyridine ([15]aneS3bpy = L), containing two pyridyl nitrogens and three thiaether sulfurs as donor atoms, has been synthesized and complexed with copper. The CuII/IL redox potential, the stabilities of the oxidized and reduced complex, and the oxidation and reduction electron-transfer kinetics of the complex rea...

The crystal structure and the magnetic properties of a heterodinuclear complex, [LCu(Me2CO)Gd(NO3)3]2 (L=N,N’-bis(2-hydroxy-3-methoxybenzylidene)-1,3-diaminopropane) are reported: [(C19H20N2O4)Cu(C3H6O)Gd(NO3)3]2, triclinic, space group P1, with a = 12.118.3(9), b = 13.562(3), c = 9.391(3) Å, α = 93.03(3), β = 107.65(2), γ = 73.07(2)◦ , V = 1406.0(7) Å3, Z = 1. The crystal structure consists of...

This report describes the dimerisation of glutathione, and by extension, other cysteine-containing peptides or protein fragments, with a 5, 5'-disubstituted-2, 2'-bipyridine or 6, 6"-disubstituted-2, 2':6',2"-terpyridine unit. The resulting bipy-GS2 and terpy-GS2 were investigated as potential metal ion dependent switches in aqueous solution, and were found to predominantly adopt the transoïd c...
