A selective and sensitive stripping voltammetric method for the determination of trace amounts of copper(II) with cyclopentanone thiosemicarbazone (CPTSC) is presented. The method is based on the adsorptive accumulation of the resulting copper-CPTSC complex on a hanging mercury drop electrode, followed by the stripping voltammetric measurements at the reduction current of the adsorbed complex a...

Thiosemicarbazones are class of compounds which obtained by the condensation thiosemicarbazide with carbonyl compounds. The transition metal complexes thiosemicarbazones widely considered due to their broad spectrum biological activities such as antibacterial, antitumor and antifungal activities. In present research work a series four novel Cu(II) aryl having general composition [Cu(L1)2Cl2], [...

We synthesized a thiosemicarbazone-functionalized flavin (Fl-(H)TSC: 2-[2-(3,4-dihydro-7,8-dimethyl-2,4-dioxobenzo[g]pteridin-10(2H)-yl)ethylidene]-hydrazinecarbothioamide) and its Pt(II) complex [Pt(Fl-TSC)(2)], and characterized it using X-ray diffraction, UV-visible absorption and luminescence spectroscopy. X-ray structural analysis for [Pt(Fl-TSC)(2)] revealed that the structure of the isoa...

The tumor-inhibitory effect of pyruvalclehyde bis(thiosemicarbazone) was greater on 6 tumors carried in male mice and rats than in females. The effect of the compound on Walker 256 in castrated male rats was similar to that seen in females. In castrated males, the antitumor activity was less than that in normal males. The injection of estradici in such castrated males did not alter the effect. ...

Palladium ion-mediated C–O activation at the C2 carbon of benzopyrone moiety 3-formylchromone-4( N )-substituted thiosemicarbazone (HL1–4) has been observed in square-planar palladium( ii ) complexes.

This study examined parameters under which risk compensation in driving can occur following the use of safety belts. Risk compensation theories hypothesize that if individuals use safety belts, they will drive in a more risky manner than if they do not use safety belts due to an increased perception of safety. Although the existence of risk compensation in driving has been debated in the litera...

The current research describes the synthesis and characterization of 2-acetylpyridine N(4)-cyclohexyl-thiosemicarbazone ligand (HL) their two metal complexes, [Au(L)Cl][AuCl2] (1) [Pd(L)Cl]·DMF (2). molecular structures compounds were determined by physicochemical spectroscopic methods. Single crystal X-ray diffraction was employed in structural elucidation new complexes. complexes showed a squ...

Bivalent metal complexes having the composition M(Phen)Cl2 (where, M = Cu(II), Ni(II) and Co(II); Phen 1,10-Phenonthroline) are reacted with 2-acetylthiophene-4-phenyl-3-thiosemicarbazone (ATPT) to produce ternary molecular formula [M(Phen)(ATPT)Cl2] H2O. The characterized using physical (molar conductivity) spectral (mass spectra, infrared electronic spectroscopies) methods. Electrochemical be...

      In the present study, aqueous solutions of some copper-complexing ligands were screened for their cytotoxicity using brine shrimp lethality test. Among the ligands tested, diacetyl-bis(N4-methylthiosemicarbazones) (ATSM) proved to be the most safe and non-toxic compound (2% lethality at 10 ppm), while pyruvaldehyde Bis(N4-methyl)thiosemicarbazone (P...
