A series of trans -Pt( ii )(salicylaldimine)(4-picoline)Cl complexes were synthesized in 78–87% yield using a one-pot procedure from commercially available precursors. The structures of these complexes were characterized by 1 H, 19 F and 13 C NMR spectroscopy, HRMS (ESI) as well as single crystal X-ray analysis. Bioactivity investigations including bio-assay, time- and dose-dependent, cell cycle progression study, caspase 3 and 9 apoptosis marker assay and DNA interaction using pBR322 plasmid DNA by gel electrophoresis were performed. The results indicated that the complexes showed promising in vitro cytotoxicity in MCF-7 and A549 cancer cell lines. Moreover these complexes enhanced the expression of p53 tumor suppressor gene family members such as p63 and p73.
