Synthesis and characterization of new biologically active palladium(II) complexes with (1E,6E)-1,7-bis(3,4-diethoxyphenyl)-1,6-heptadiene-3,5-dione

Two new palladium complexes with (1E,6E)-1,7-bis(3,4-diethoxyphenyl)-1,6-heptadiene-3,5-dione, 1 and 2, have been synthesized and structurally characterized. Complex 1 has the molecular structure confirmed by X-ray diffraction measurements. Both complexes display a significant antiproliferative activity against human colorectal cancer cells by inducing early and late apoptotic processes in those cells.
