Abstract: Two novel oxovanadium(IV) complexes ([VO(hntdtsc)(BPIP)] and [VO(hntdtsc)(MOPIP)] (hntdtsc = 2-hydroxy-1-naphthaldehydethiosemicarbazone, BPIP = 2-(4-bromophenyl)-imidazo[4,5- f]-1,10-phenanthroline, MOPIP = 2-(4-methoxyphenyl)-imidazo[4,5- f]1,10-phenanthroline), are synthesized and characterized. Subsequently, the Methyl Thiazolyl Tetrazolium (MTT) assay is used to investigate the antitumor activity of the ligand and two… read more here.
