Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -New Mn(II), Co(II), Ni(II), Cu(II), Zn(II) and Cd(II) complexes with chelating ligand (Z)-(2-((1,3-diphenyl-1H-pyrazol-4-yl)methylene) hydrazinyl)(pyridin-2-ylamino) methanethiol were synthesized and characterized efficiently with different spectral methods. Antioxidant activity revealed that Cd(II) complex showed the highest inhibitory antioxidant activity either using ABTS method. The SOD-like activity exhibited those Cd(II) and Zn(II) complexes have strong antioxidative properties. Ni(II), Zn(II) and Cd(II) complexes were good at inhibiting the tumour cells compared to the free ligands. Ni(II) complex shows excellent activity similar to that of Fluorouracil. 56 pp. Englisch.…

Taschenbuch. Condición: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - This book highlighted the methods used for the syntheses of thiosemicarbazide and their metal complexes. Molecular modelling for all prepared compounds was investigated. Dissociation and formation constants were calculated for ligands and complexes respectively. In vitro and in vivo studies for thiosemicarbazides showed high potent antitumor activity. Finally, this book reported thiosemcarbazide derivatives as organic chelates (which are not pollutant for water media and may have biological importance) for the separation of about 100% of Hg2+, Mn2+ and Cd2+ ions.…
