Abstract: Purpose:To study the breaking effects of Cisplatin, Carboplatin and Dicycloplatin on pBR322 plasmid DNA. Methods:Agrose gel electrophoresis and Gel image analysis was used. Results:All three platinum-species drugs could cause DNA break of pBR322 plasmid. The FC50 of Cisplatin, Carboplatin and Dicycloplatin were 33.71 μmol/L, 3.31 mmol/L, and 1.61 mmol/L , respectively. Conclusion:Breaking effects of tested drugs: Cisplatin > Dicycloplatin > Carboplatin.

Key words: cisplatin;carboplatin;dicycloplatin;DNA break;agrose gel electrophoresis, gel image analysis
