The use of 2,6-DMHQ in ischemia-reperfusion-related injuries, preferably against cardiac and hepatic ischemia-reperfusion injuries. 2,6-DMHQ can reduce serum ALT and AST and ameliorate liver necrosis. 2,6-DMHQ can also reduce the cardiac enzyme profile, including CK, CK / MB and LDH, and reduce myocardial infarct size.
