![عکس صفحه اول مقاله: Synthesis and cytotoxic effect on RD cell line of Pd(II) and Cu(II) Synthesis and cytotoxic effect on RD cell line of Pd(II) and Cu(II)](/preview/png/229435.png)
Complexes of Cr(III), Cd(II), Ni(II), Pd(II) and Cu(II) with new ligand sodium [5-(p-nitro phenyl)-/4-phenyl-1,2,4-triazole-3-dithiocarbamato hydrazide] (TRZ.DTC) have been prepared and characterized in solid state by using flame atomic absorption, elemental analysis C.H.N.S, FT-IR, UV–vis spectrophotometry, thermal analysis TGA, conductivity and magnetic susceptibility measurements. The ratio of M:L and log K was determined by molar ratio method. From the spectral studies, an octahedral monomer structure was proposed for all complexes except copper(II) which has a dimeric structure. Cadmium(II) has tetrahedral geometry. Structural geometries of these compounds were also suggested in gas phase by using hyper chem-8 program. The heat of formation, binding energy, and dipole moment were calculated by PM3 and ZINDO/1 methods. ZINDO/1 was used to evaluate the vibration spectra of the (TRZ.DTC) ligand and starting material as authentic compound. Cytotoxic effect of Pd, Cu and ligand was evaluated against Rhabdomyosarcoma cell line by using four different concentrations (500, 250, 125 & 62.5 μg/ml) in three exposure times 24, 48 and 72 h and compared this effect with control positive Cis-Pt. The efficiency of these new compounds on RD cell line may be attributed to blocking the protein synthesis of the cells.
