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 novel palladium(II) complexes containing a curcumin analogue are synthesized.
• β-diketone ligand coordinates to Pd ion through carbonylic oxygen atoms.
• The structure of complex 1 is confirmed by X-ray diffraction.
• X-ray powder diffraction for bulk sample is identical with the refined structure.
• Complexes 1 and 2 induce apoptosis on human colorectal cancer cells.

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.
