Of the six benzoylpyridine thiosemicarbazone ligands used in this study, two are reported for the first time;2-benzoylpyridine tert-butyl thiosemicarbazone (BZP-tBTSC), and 2-benzoylpyridine benzyl thiosemicarbazone (BZP-BzTSC). Once characterized by NMR, melting point, and MS, these mono-anionic tridentate ligands were then reacted with Cu<sup>2+</sup> to form the new square planar metal complexes [Cu(BZP-tBTSC)Cl] and [Cu(BZP-BzTSC)Cl]. All of the copper complexes display marked inhibition of human topoisomerase IIα. The [Cu(BZP-tBTSC)Cl] complex shows marked activity against human breast cancer cell lines.展开更多

This ligand coordinates to the metal ions in a tridentate monoanionic fashion forming monometallic complexes with the formula [M(APZ-tBTSC)Cl]. The ligand and the three metal complexes [Cu(APZ-tBTSC)Cl], [Pd(APZ-tBTSC)Cl], and [Pt(APZ-tBTSC)Cl] were tested for anti-proliferative biological behavior with a panel of seven microbes, and the copper and palladium complexes were found to be highly active against Gram positive bacteria. The 4 compounds were also tested in human topoisomerase IIα DNA relaxation assays and all three metal complexes had topoisomerase inhibition at a concentration between 4 - 6 micro-molar. The 4 compounds were also tested for activity with the HEK293T cell line and also the breast cell cancer line, MDA-MB-231. The most effective compound for activity against the HEK293T cell line was the [Cu(APZ-tBTSC)Cl] complex, and the MDA-MB-231 breast cancer cell line was the [Pt(APZ-tBTSC)Cl] complex.展开更多
