Polynuclear transition metal complexes with thiocarbohydrazide and dithiocarbamates
TL;DR: The in vitro antibacterial activity of Sn(tch)2{M2(dtc)4} and the mononuclear Sn(uch)2 has been carried out on bacterial strains Escherichia coli and Salmonella typhi and the compounds were found to be active against the test organisms.
Journal ArticleDOI
Thiohydrazone copper(II) complexes. The relationship between redox properties and superoxide dismutase mimetic activity.
TL;DR: It follows that the structure and conformation of ligand has influence on the redox potential of central atom in coordination compound and the changes in the coordination sphere are connected with the change of biological function of compounds represented by SOD-mimic activity.
