In this investigation, we have designed and synthesized a new Ru(II)-arene complex with triarylamine thiosemicarbazone hybrid ligand to explore its cytotoxicity. The ligand and the complex were well characterized by spectroscopic techniques. From the single-crystal X-ray crystallography, the molecular structure of the ligand was confirmed to be monoclinic lattice withC12/C1space group symmetry. X-ray photoelectron spectroscopy(XPS) studies ensured that ruthenium is in +2 oxidation state. The synthesized Ru(II)-arene complex was thoroughly investigated for thein vitroactivity against human breast carcinoma (MCF-7), human colon carcinoma (COLO 205), human neuroblastoma (IMR-32), murine microphage (Raw 264.7) and embryonic kidney (HEK 293) using MTT assay. The interaction of the Ru(II)-arene complex with DNA/protein was also explored by absorption and emission spectral methods. This investigation highlights the role of hybrid ligand and its Ru(II) complex toward high cytotoxicityin vitro. The complex has high cytotoxic effect with IC(50)value of 5.18 +/- 1.128 mu M toward human breast carcinoma cell line.
