title: [Experimental study on anti-cancer effect of Cantharidine derivatives and platinum complex].
abstract: OBJECTIVE
  To certify the anti-tumor effects of the four Cantharidine derivatives and platinum complex on transplanted tumor in mice to search for new anti-tumor drugs.
  
  
  METHODS
  Complex of four Cantharidine derivatives (Dpt 1-15, Dpt 5-10, Dpt 12-3 and Dpt6-2) and platinum were given to tumor beating mice of transplanted S180 sarcoma, H22 solid hepatocarcinoma and ascites hepatocarcinoma through intraperitoneal or intravenous injection, and the effect of treatment on tumor weight and survival of animal were observed. Cisplatin was used as positive control and 0.9% normal saline used as negative control. All data were treated with t test.
  
  
  RESULTS
  All the four complex had anti-tumor effect. The inhibition rate of Dpt5-10 and Dpt1-15 on S180 sarcoma and H22 solid hepatocarcinoma and the survival prolongation rate of Dpt5-10 on H22 ascites hepatocarcinoma were similar to those of cisplatin. The toxicity of effective dose of Dpt1-15 was rather high.
  
  
  CONCLUSIONS
  Cantharidine derivatives and platinum complex is new effective anti-tumor drug, among them the Dpt5-10 is the most effective one. Further study for improving the solubility of drug is necessary and study the difference of cross resistance between the new complex and cisplatinum.
