Abstract: A new Schiff base 3,4-methylenedioxy-phenethylamine-pyridine-2-formaldehyde (L),was synthesized as ligand.The reaction of L with PdCl2 afforded the first palladium(Ⅱ) complex of L (complex 1).Complex 1 was characterized by IR,elemental analysis,ESI-MS,and structurally determined by X-ray single crystal diffraction analysis.In vitro cytotoxicity test against six human tumor cell lines by MTT method showed that complex 1exhibited significant cytotoxicity against the MDA-MB-231 tumor cell,with IC50 value of (6.98±1.43) μmol/L,while low cytotoxicity to the other fivetumor cell lines (including A549,HeLa,NCI-H460,MGC80-3 and BEL7404),which indicatedthat complex 1 showed some cytotoxic selectivity on these tested tumor cell lines,suggesting its potential for the antitumoral applications.

Key words: Schiff base, palladium(Ⅱ) complex, crystal structure, antitumor activity
