  Copper(II) complexes of 2-benzoylpyridine 4N-substituted thiosemicarbazones

  摘要：

  2-Benzoylpyridine N-4-substituted thiosemicarbazones commonly coordinate as neutral tridentate ligands to give five coordinate [Cu(HL)Cl-2] complexes when prepared in boiling isopropanol. However, when prepared in boiling ethanol, the anion (loss of the N-3-hydrogen) coordinates as a tridentate ligand to give [CuLCl] complexes. Representative crystal structures of both stoichiometries have been determined. Spectral characterization of both the 2-benzoylpyridine N-4-substituted thiosemicarbazones and their copper(II) complexes includes IR, UV-vis, EPR and NMR studies. Growth inhibition studies of the thiosemicarbazones and their complexes were performed against two human pathogenic fungi.

  Novel Second-Generation Di-2-Pyridylketone Thiosemicarbazones Show Synergism with Standard Chemotherapeutics and Demonstrate Potent Activity against Lung Cancer Xenografts after Oral and Intravenous Administration in Vivo

  摘要：

  We developed a series of second-generation di-2-pyridyl ketone thiosemicarbazone (DpT) and 2-benzoylpyridine thiosemicarbazone (BpT) ligands to improve the efficacy safety profile of these potential antitumor agents. Two novel DpT analogues, Dp4e4mT and DpC, exhibited pronounced and selective activity against human lung cancer xenografts in vivo via the intravenous and oral routes. Importantly, these analogues did not induce the cardiotoxicity observed at high nonoptimal doses of the first-generation DpT analogue, Dp44mT. The Cu(II) complexes of these ligands exhibited potent antiproliferative activity having redox potentials in a range accessible to biological reductants. The activity of the copper complexes of Dp4e4mT and DpC against lung cancer cells was synergistic in combination with gemcitabine or cisplatin. It was demonstrated by EPR spectroscopy that dimeric copper compounds of the type [CuLCl](2), identified crystallographically, dissociate in solution to give monomeric 1:1 Cu:ligand complexes. These monomers represent the biologically active form of the complex.
