During the period of biosynthesis, cinnamic acid is the precursor substances of salicylic acid which is the endogenous signal molecule in plant. The interaction of cinnamic acid (cin), phenanthroline (phen) and its ternary complexes (RE=Nd(Ⅲ), Ce(Ⅲ), Eu(Ⅲ)) with calf thymus DNA was investigated by electronic absorption spectroscopy, ethidium bromide (EB)-DNA quenching fluorescent spectroscopy and resonance light scattering as well as the effect of EB fluorescence spectroscopy in the presence of DNA. All experimental results indicate that the three complexes bind to DNA by the electrostatic mode and the intercalation mode. It is predicted that these complexes show high antitumor activity or other biologic activity.
