Abstract :

In this research, some of the inorganic complexes of uranyl with N- donor ligandswere synthesized. Complexes were characteriezed by FT-IR and UV spectra, ¹HNMR,¹³CNMR and some physical properties. The uranyl unit (UO2) is composed of a center ofuranium atom with the charge (+6) and two oxygen atom by forming two U=O double bonds.The structure is linear (O=U=O, 180) and usually stable. So other ligands often coordinate tothe U atom in the plane perpendicularly to the O=U=O axis. The antitumor activity of some ofligand and their complexes against a panel of human tumor cell lines (HT29: Haman colonadenocarcinoma cell line T47D: human breast adenocarcinoma cell line) were determined byMTT(3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl-tetrazolium bromide) assay. These datasuggest that some of these compounds provide good models for the further design of potentantitumor compounds.
