Antimelanomal activity of the copper(II) complexes of 1-substituted 5-amino-imidazole ligands against B16F10 mouse melanoma cells.

ABSTRACT

The copper complexes of 5-amino-imidazole ligands were prepared and characterized by various spectroscopic techniques. The ligand geometry around the copper(II) centre is square pyramidal based on N2O2 donor atoms and a coordinated water molecule at the apex. Single crystal X-ray structures were determined for both ligands. Ligands and copper complexes exhibited dose-dependent antiproliferative effects on the growth of B16F10 melanoma cells line but lower IC50 values were observed for the copper complexes.
