PURPOSE:To investigate the hepatotoxicity and nephrotoxicity of 3-Bromopyruvate (3BP) in mice.METHODS:Fifteen nude mice were grafted subcutaneously in the left flank with MDA-MB-231 cells, then all mice were divided into control group (PBS), 3BP group (8 mg/kg), positive group (DNR: 0.8 mg/kg) when tumor volume reached approximately 100 mm3. 28 days later, tumors, livers and kidneys were stored in 4 % formalin solution and stained with hematoxylin and eosin staining. The Kunming mice experiment included control group (PBS), 3BP group (4mg/kg; 8mg/kg; 16mg/kg), positive group (DNR: 0.8 mg/kg). 24 hours later, the blood were used for the determination of hepatic damage serum biomarkers. Livers were stored in 4 % formalin solution for the later detection.RESULTS:3BP at the dose of 8mg/kg had a good effect on inhibiting tumor growth in nude mice and did not damage liver and kidney tissues. Kunming mice experiment showed 3BP at the dose of 16mg/kg did damage to liver tissues.CONCLUSION:3-Bromopyruvate at the dose of suppressing tumor growth did not exhibit hepatotoxicity and nephrotoxicity in nude mice, and the effect on liver was confirmed in Kunming mice.(AU)
