SYNTHESIS, CHARACTERIZATION, DNA-BINDING, PHOTOCLEAVAGE AND ANTI-MICROBIAL STUDIES OF COMPLEX [Ru(4-ETHYL- PYRIDINE)4(DPPZ)]2+Abstract
The new Ru (II) complex [Ru(4-Et-py)4(dppz)]2+ (dppz = dipyrido phenazine) have been synthesized and characterized by different analytical techniques like elemental analysis, LC-MS, 1H NMR , 13C NMR. The interaction of this complex with calf thymus DNA has been explored by U.V. absorption spectroscopy, Fluorescence measurements, and viscosity measurements. Their photocleavage behavior towards pBR 322 and anti-bacterial properties of this complex was also investigated. The experimental results show that the complex binds with DNA by intercalation mode.
