The present disclosure generally pertains to methods of treating myocardial infarct involving administering a platelet anti-aggregate, a cysteine-aspartic protease inhibitor, and reperfusion therapy. In certain embodiments, the platelet anti-aggregate is at least one P2Yreceptor antagonist or Glycoprotein IIb/IIIa inhibitor, the cysteine-aspartic protease inhibitor is selected from the group consisting of Caspase-1, 4, 5, 11 and 12 inhibitors, and reperfusion therapy is percutaneous coronary intervention. In certain embodiments, the at least one P2Yreceptor antagonist is selected from the group consisting of cangrelor, ticagrelor, clopidogrel and prasugrel. The disclosed methods provide an improved cardioprotective effect against infarction when compared with the current standard of care.

Combined administration of cysteine-aspartic protease inhibitors with P2Y12 receptor antagonists protects the heart against myocardial infarction

Fostriecin and a compounds structurally related to fostriecin diminish myocardial infarction and delay the onset of cell injury in an ischemic heart. There is a strong correlation between myocardial protection and the inhibition of certain serine/threonine protein phosphatases. The present invention is drawn to a method for administering fostriecin as a pharmacological compound to reduce the size of a myocardial infarction. Further, administration of fostriecin is useful also as an adjunct therapy to treatment with thrombolytic agents or angioplasty to limit the size of infarction. The most advantageous feature of the method of the present invention is that administration of fostriecin diminishes infarct volume and cell injury even when added after ischemia conditions occurred. In addition to the use of the method of the present invention for limiting damage due to myocardial infarction, the method of the present invention can be employed to delay damage associated with tissue storage for organ transplantation.

Method for diminishing myocardial infarction using protein phosphatase

Methods for protecting tissues and organs including the heart central nervous system, and kidney from ischemic damage are described and claimed based upon the recognition that protection against infarction is mediated by A3 rather than A1 adenosine receptors, as was previously thought, and that the receptor mediating protection in other organs and tissues has not been defined. Methods for selectively stimulating A3 adenosine receptors are described and claimed, as such selection is shown to prevent or substantially reduce cell death resulting from ischemia with or without reperfusion in humans. According to this invention, the A3 adenosine receptor is selectively stimulated by administering a compound which is an A3 adenosine receptor-selective agonist. Prevention of tissue death is also achieved by administering a compound which is a non-selective adenosine receptor agonist together with compounds that act as antagonists to the A1 and A2 adenosine receptor.
