title: Cytotoxic effect, differentiation, inhibition of growth and theoretical calculations of an N,N-donor ligands and its platinum(II), palladium(II) and copper(II) complexes.
abstract: The new pyrazole ligand 5-(2-hydroxyphenyl)-3-methyl-1-(2-pyridylo)-1H-pyrazole-4-carboxylic acid methyl ester (2) and the corresponding Pt(II), Pd(II) and Cu(II) complexes 3-5 have been synthesized as potential anticancer compounds, and characterized using IR, and (1)H NMR as well as mass spectrometry. The 3-D structures of the Cu(II) complexes were determined by quantum mechanic calculation DFT methodology (density functional theory). The cytotoxicity assay of the ligand and complexes has been performed on leukemia cell lines. In general, the complexes showed lower cytotoxicity than cisplatin, and the Pt(II) and Cu(II) complexes were found to be more efficient in the induction of leukemia cell death than the Pd(II) complex. Our investigations indicate that the antiproliferating activity of the Pt(II) and Cu(II) complexes was partly due to the modulation of cellular differentiation.
