Effect of cisplatin and 6-bromo-6-deoxy-L-ascorbic acid on some biochemical and functional parameters in mice
The results of the present study demonstrate that 6-bromo-6-deoxy-L-ascorbic acid (6-BrAA), an antioxidative derivative of ascorbic acid is capable of lowering the toxicity of cisplatin, cis-diaminedichloroplatinum (cis-DDP), an anticancerogenic drug. The biological aspects and pharmacological significance of combined treatment of these two substances were investigated in a mouse model. The results indicate that the effectiveness of 6-BrAA no biological response(s) is strongly dependent on the dose of cis-DDP. Injection of 10 mg/kg body weight (bw) of cis-DDP following pretreatment with 6-BrAA (480 mg/kg bw) enhances the tissue-protecting effect of 6-BrAA and reduce, to some extent, the ensuing nephro-, liver and spleen toxicity. On the other hand, 6-BrAA in animals treated with higher dose of cis-DDP (15 mg/kg bw) leads to exacerbation of the toxic cis-DDP effect and concurrent loss of the protective potential of 6-BrAA with respect to tissue damage. The exact mechanism(s) of 6-BrAA protection and exarcebation of the toxic cis-DDP effect is unclear, although scavenging or generating of free radicals may play important role. The results obtained may be of importance in planning the rational use of cis-DDP and 6-BrAA administration potential treatment of cancer.
