Two novel compounds of vanadium and molybdenum with carnitine exhibiting potential pharmacological use.

Two novel compounds of vanadium and molybdenum with carnitine exhibiting potential pharmacological use. J Inorg Biochem. 2014 Oct 22;142C:109-117 Authors: Galani A, Tsitsias V, Stellas D, Psycharis V, Raptopoulou CP, Karaliota A Abstract The reaction of sodium orthovanadate with carnitine hydrochloride molecule results in the precipitation of decavanadate compound of carnitine whereas the reaction of metallic molybdenum with hydrogen peroxide and carnitine results in the peroxo-molybdenum complex of carnitine. The decavanadate compound as well as the molybdenum complex of carnitine have been characterized by means of elemental analysis, IR, electronic spectra, (1)H NMR, 2D-COSY-NMR (=correlation spectroscopy) and thermo-gravimetric analysis (TGA). In addition decavanadate compound of carnitine was fully characterized by X-ray crystallography. The analytical data were in good agreement with the empirical formulae of both, decavanadate compound and molybdenum complex. The two compounds were also evaluated for cell toxicity and their anticancer activity by the MTT(3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide)-based assay method, using primary cells and tumor cell lines of both human and murine origins and the results show that compound 1 shows an increased biological activity in comparison with compound 2. Moreover using confocal microscopy and antibodies against cleaved caspase 3 we further analyzed the cell toxicity an...
