Dl-3-n-butylphthalide attenuates myocardial ischemia reperfusion injury by suppressing oxidative stress and regulating cardiac mitophagy via the PINK1/Parkin pathway in rats.

ABSTRACT:

Background

Acute myocardial infarction (AMI) is one of the leading causes of mortality worldwide. Undesirable myocardial damage may occur during reperfusion of the ischemic myocardium, and this is known as "ischemic reperfusion injury" (IRI). Currently, there are few effective drugs to alleviate IRI. Dl-3-n-butylphthalide (NBP) is recommended for the treatment of acute ischemic stroke in China. This study investigated the effects of NBP on IRI and its underlying mechanisms.

Methods

The left anterior descending (LAD) coronary arteries of rats were occluded for 30 minutes and reperfused for 6 hours to establish the ischemia/reperfusion (I/R) model. NBP was administered intraperitoneally 2 hours before modeling and immediately after reperfusion. At 6 hours after reperfusion, 2,
