Abstract
Copper(II) complexes [Cu(Fc-aa)(cur)] (1–3) of curcumin (Hcur) and N-ferrocenylmethyl-l-amino acids (Fc-aa), viz., ferrocenylmethyl-l-tyrosine (Fc-TyrH), ferrocenylmethyl-l-tryptophan (Fc-TrpH) and ferrocenylmethyl-l-methionine (Fc-MetH), were prepared and characterized. The DNA photocleavage activity, photocytotoxicity and cellular localization in HeLa and MCF-7 cancer cells of these complexes were studied. Acetylacetonate (acac) complexes [Cu(Fc-aa)(acac)] (4–6) were prepared and used as controls. The chemical nuclease inactive complexes showed efficient pUC19 DNA cleavage activity in visible light. Complexes 1–3 showed high photocytotoxicity with low dark toxicity thus giving remarkable photodynamic effect. FACScan analysis showed apoptosis of the cancer cells. Fluorescence microscopic studies revealed primarily cytosolic localization of the complexes.
