Abstract: Pingyangmycin is an antitumor antibiotics. The therapeutic activity is to degrade template DNA or interfer DNAbiosynthesis. It is necessary for the degradation of DNA to have O2and a metal ion. However,the effect of divalent metal ions on the interaction between Pingyangmycin and DNA is quite different from those of various ions. In this paper, we reported the effect of Fe2+, Co2+, Cu2+, Zn2+and Mg2+etc. on DNA clevaged by Pingyangmycin with agarose electrophoresis and CDspectra. The results showed that the degradation of DNAin the presence of Pingyangmycin was obviously increased by Fe2+or Co2+and inhibited by Cu2+, Zn2+or Mg2+. Meanwhile, the possible mechanism of the two kinds of divalent metal ions for the interaction between Pingyangmycin and DNA was also discussed.
