A novel three components approach for the synthesis of bioactive Ru–arene pyridinylmethylene complexes has been developed using pyridine carboxaldehyde, amino pyridine and dichloro (p-cymene) ruthenium(II) dimer as starting materials. These scaffolds were screened for their anticancer activity against breast cancer (MCF7) and human Epitheloid Cervix Carcinoma (HeLa) cell line. It was established that compounds [(η6-pcymene)RuCl(κ2-N,N-(3,5-dinitro-pyridin-2-yl)-pyridin-2-ylmethylene-amine)]PF6 (4o), [(η6-pcymene)RuCl(κ2-N,N-N-(3,5-dibromo-pyridin-2-yl)-pyridin-2-ylmethylene-amine)]PF6 (4c), [(η6-pcymene)RuCl(κ2-N,N-(3,5-dibromo-6-methylpyridin-2-yl)-pyridin-2-ylmethylene-amine)]PF6 (4j) and [(η6-pcymene)RuCl(κ2-N,N-3(3-bromo-5-methyl-pyridin-2-yl)-pyridin-2-ylmethylene-amine)]PF6 (4b) were significantly active against both the cell lines.
