Purpose: evaluating the relationship between oxidative damage oxaliplatin (OXA)-induced and the therapeutic potential of 7-chloro-4-(phenylselanyl) quinoline (4-PSQ) in kidney of mice.
Methods: Mice received OXA (10 mg/kg) or vehicle by intraperitoneal route (days 0 and 2). Oral administration of 4-PSQ (1 mg/kg) or vehicle was performed on days 2 to 14. On day 15, the animals were euthanized, and the kidneys and blood collected. The effect of OXA and/or 4-PSQ on urea, thiobarbituric acid reactive species (TBARS), non-protein thiol (NPSH) and protein carbonyl (PC) levels were investigated. Moreover, renal superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione reductase (GR), glutathione S-transferase (GST), δ-aminolevulinic acid dehydratase (δ-ALA-D) and Na+, K+ ATPase activities were evaluated.
Results: Our findings revealed an increase on urea levels and a significant renal oxidative damage in OXA-induced mice. OXA exposure increased SOD, GPx and GST activities and caused a reduction on NPSH levels, CAT and GR activities. Na+, K+ ATPase and -ALA-D activities were reduced by OXA. 4-PSQ decreased plasmatic urea levels and renal oxidative damage. SOD, GPx, CAT, GR and Na+, K+ ATPase activities were restored by 4-PSQ.
Conclusion: 4-PSQ may be a good prototype for the treatment of OXA-induced renal injury.
