Regulation of myocardial ischemia reperfusion injury signal pathway by flavonoid monomer / 中国中药杂志

ABSTRACT

Acute myocardial infarction seriously endangers the health of people due to its high morbidity and high mortality. Reperfusion strategy is the preferred treatment strategy for acute myocardial infarction. However, reperfusion may lead to additional heart damage, namely myocardial ischemia reperfusion injury(MIRI). Therefore, how to reduce myocardial ischemia reperfusion injury has become one of the urgent problems to be solved in cardiovascular disease. Traditional Chinese medicine(TCM) has the multi-component, multi-channel, and multi-target advantages in the treatment of MIRI, which offers new ideas in this aspect. TCM containing flavonoids has a variety of biological activities and plays a significant role in the treatment of MIRI, which has great research and development application value. TCM containing flavonoids can regulate multiple signaling pathways of MIRI, such as phosphatidylinositol 3 kinase/kinase B(PI3K/Akt) signaling pathway, Janus kinase/signal transducer and activator of transcriptions(JAK/STAT) signaling pathway, adenosine 5'-monophosphate(AMP)-activated protein kinase(AMPK) signaling pathway, mitogen-activated protein kinase(MAPK) signaling pathway, nuclear factor-erythroid 2-related factor 2/antioxidant response element(Nrf2/ARE) signaling pathway, nuclear factor kappa-B(NF-κB) signaling pathway, silent information regulator 1(Sirt1) signaling pathway, and Notch signaling pathway. It reduces MIRI by inhibiting calcium overload, improving energy metabolism, regulating autophagy, and inhibiting ferroptosis and apoptosis. Therefore, a review has been made based on the regulation of relative signaling pathways against MIRI by TCM containing flavonoids, thus providing theoretical support and potential therapeutic strategies for TCM to alleviate MIRI.
