Mildronate (3-(2,2,2-trimethylhydrazinium) propionate), which is mostly used in cardiological practice and is considered an anti-ischemic drug, was designed to inhibit carnitine biosynthesis in order to prevent accumulation of cytotoxic intermediate products of fatty acid beta-oxidation. Recently it was shown that the mitochondrial respiratory chain may also be a target for mildronate action. In this study, we aimed to investigate whether mildronate can protect the liver against a 90-min normothermic ischemia/30-min reperfusion-induced mitochondrial dysfunction. ⋯ No steatotic livers were observed in any experimental groups after mildronate pre-treatment. In conclusion, 90 min of liver ischemia followed by a 30 min reperfusion has a deleterious effect on rat liver mitochondrial function. Mildronate pre-treatment of rats at doses of 100 or 200 mg/kg/day for one or two weeks did not prevent ischemia/reperfusion-induced mitochondrial dysfunction and liver injury.
