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...
In order to get insight into the trypanocidal mechanism of action of a series of 5-nitrofuryl containing thiosemicarbazones some studies related to their bioreduction were performed. Electron spin resonance spectra of radicals generated in T. cruzi by compounds' bioreduction were analyzed. Three different patterns of ESR signals were observed for the different assayed compounds. These results w...
background: due to interesting tumor imaging properties of bis-thiosemicarbazones, [103pd]-di-acetyl-bis (n4-methylthiosemicarbazone) ([103pd] atsm2) was prepared according to the analogy of radio copper homologues. materials and methods: palladium-103 (t1/2=16.96 d) was produced via the 103rh (p,n) 103pd nuclear reaction with proton energy 18 mev. the final activity was eluted in form of pd (n...
The reactions of bis(cyclopentadienyl)titanium(IV) dichloride with a new class of thiosemicarbazone (LH(2)), derived by condensing isatin with different N(4)-substituted thiosemicarbazides, have been studied and products of type [Cp(2)Ti(L)] have been isolated. On the basis of various physico-chemical and spectral studies, five coordinate structures have been assigned to these derivatives. Toxi...
Four ruthenium(II) complexes of the type [RuCl(CO)(py)(PPh3)L] (L= thiosemicarbazone ligand) have been synthesized and the structural features were determined by various physico-chemical and spectral techniques. The thiosemicarbazone ligands act as bidentate, monobasic chelating ligands with S and N as the donor sites and are preferably found in thiol form in all the complexes studied. In order...
A series of ferrocenyl- and aryl-functionalised organosilane thiosemicarbazone compounds was obtained via a nucleophilic substitution reaction with an amine-terminated organosilane. The thiosemicarbazone (TSC) ligands were further reacted with either a ruthenium dimer [(η(6-i)PrC6H4Me)Ru(μ-Cl)Cl]2 or a rhodium dimer [(Cp*)Rh(μ-Cl)Cl]2 to yield a series of cationic mono- and binuclear complexes....
