Cancer is one of the leading causes of death worldwide and there is an increasing need for novel anti-tumor therapeutics with greater selectivity and potency. A new strategy in the treatment of cancer has focused on targeting an essential cell metabolite, iron (Fe). Iron is vital for cell growth and metabolism, forming a crucial component of the active site of ribonucleotide reductase (RR), the...
ABSTRACT Ru(II)BT have been synthesized by the reaction between substituted bromobenzal thiosemicarbazones and precursors of ruthenium metal complexes, [RuHCl(CO)(EPh3)3] (where E = P/As). The Ru(II)BT was characterized analytical spectroscopic techniques. It confirms coordination thiosemicarbazone ligands suggest octahedral geometry complexes. is comprised a centre with bidentate ligands. s...
The composition and stability of the complexes of isatin-β-thiosemicarbazone with Co(II), Ni(II), Cu(II), Zn(II), Pd(II) and Hg(II) have been investigated using spectrophotometric method at 30 °C and constant ionic strength of 0.1 mol dm-3 (KNO3) in 70 % ethanol. Experimental results indicate the formation of MeL and MeL2 complexes for Ni(II) and Co(II), and MeL for Cu(II), Zn(II), Pd(II) and H...
