摘要：

Metal-based cancer chemotherapeutic agent of the type Co(II) complex [Co(mpca)(2)].H(2)0 (1), where, Hmpca = 9-methyl-[1,10] phenanthroline-2-carboxylic acid was synthesized and characterized by various spectroscopic and analytical techniques and further authenticated by single crystal X-ray diffraction methods. In vitro DNA binding studies of complex 1 with CT DNA was carried out by several biophysical techniques in accordance with molecular docking technique which revealed that 1 binds to DNA via intercalation mode having GC-rich sequences. Complex 1 cleaves pBR322 DNA via hydrolytic pathway (validated by T4 DNA ligase assay). Furthermore, complex 1 exhibits significant inhibitory effects on the catalytic activity of Topo-I at 25 mu m concentration and further validated by molecular docking studies.
