Studies on Dna Interaction With 2(3),9 16(17), 23(24)-Tetrakis 2((4-Phenoxyphenyl) Diazeylbenzoic Acid)phthalocyaninato Zinc (Ii) Compound

Abstract

In this study, 2(3), 9(10), 16(17), 23(24)-tetrakis 2((4-phenoxyphenyl) diazeylbenzoic acid)phthalocyaninato zinc (II) compound was chosen to study DNA binding activities. The binding activities of zinc (II) phthalocyanine compound bearing 2(3),9(10), 16(17), 23(24)-tetrakis 2((4-Phenoxyphenyl) diazeylbenzoic acid) ligand with Calf Thymus (CT)-DNA was investigated using absorption titration, fluorescence spectroscopy, cyclic voltammetry and thermal melting profile in a Tris-HCl buffer system at pH7.0. In addition to these methods, gel electrophoresis and viscosity measurements were also carried out to determine DNA binding activities with compound 6 in a buffer solution. The results indicated that compound 6 interacts with CT-DNA through partial intercalation binding mode.
