Cellular confocal fluorescence studies and cytotoxic activity of new Zn(II) bis(thiosemicarbazonato) complexes

Dalton Trans. 2008 Apr 28:(16):2107-10. doi: 10.1039/b802806k. Epub 2008 Mar 18.

Abstract

We report the synthesis and characterisation of new, highly fluorescent, zinc complexes of bis(thiosemicarbazone) ligands incorporating extended aromatic backbones which are cytotoxic at levels comparable to cisplatin; cellular fluorescence imaging studies suggest these cause cell death by disruption of mitochondria.
