Introduction. Polyoxometalates (POMs) are negatively charged inorganic aggregates that possess potential antibacterial, anticancer, antidiabetic and antiviral effects. Although toxicity evaluation of drug candidates is necessary, reports of relevant toxicological studies of these compounds are relatively rare. Aims. Since our preliminary results demonstrated biological activities of the donut-shaped POM {NaP5W30} (POM1) and the Ag + -containing derivative POM {AgP5W30} (POM2), the aim of present study was to evaluate their toxicological effects in vivo, using Wistar albino rats as an experimental model. Methods. Animals (n = 6 per group) were orally treated with investigated POMs in daily doses of 20 mg/kg body weight for 14 days when the rats were sacrificed and blood samples were collected. The biochemical markers of renal (serum concentrations of urea - SUr and creatinine - SCr) and liver function (serum concentrations of total protein–TP and albumin - Alb, serum activities of asp...artate aminotransferase - AST and alanine transaminase - ALT) were determined spectrophotometrically. Results. The POM1 and POM2 were induced statistically significant increasing of SUr (in: mmol/L) (7.95 ± 0.35 and 6.83 ± 0.26 vs. 4.97 ± 0.47; p < 0.001 and p < 0.01, respectively) and SCr (in: mmol/L) (41.34 ± 0.84 and 39.06 ± 1.07 vs. 32.27 ± 0.61; p < 0.001 and p < 0.001, respectively) compared to the control group. Also, investigated compounds induced statistically significant decreasing of TP (in: g/L) (60.16 ± 1.43 and 58.53 ± 0.81 vs. 67.86 ± 0.03; p < 0.001 and p < 0.001, respectively) and Alb (in: g/L) (29.34 ± 0.58 and 29.45 ± 0.81 vs. 34.89 ± 0.41; p < 0.001 and p < 0.001, respectively) compared to the control group. In contrast, there was no statistically significant difference in AST and ALT between the untreated and treated groups (p > 0.05). Conclusion. Obtained results suggested that both investigated POMs induce kidney injury as well as synthetic dysfunction of liver. Thus, their potential clinical application would require a more complex toxicological study.
