Efficient one-pot synthesis of trans- Pt(II)(salicylaldimine)(4-picoline)Cl complexes: Effective agents for enhanced expression of p53 tumor suppressor genes

peer reviewedA series of trans-Pt(II)(salicylaldimine)(4-picoline)Cl complexes were synthesized in 78‒87% yield using one-pot procedure from commercially available precursors. The structures of these complexes were characterized by 1H, 19F and 13C NMR spectroscopy, HRMS (ESI) as well as single crystal X-ray analysis. Bioactivity investigations including bio-assay, time- and dosedependent, 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
