Rhynchophylline ameliorates myocardial ischemia/reperfusion injury through the modulation of mitochondrial mechanisms to mediate myocardial apoptosis

Rhynchophylline (RP), the primary active ingredient of Uncaria rhynchophylla, has an anti‑hypertensive effect and protects against ischemia‑induced neuronal damage. The present study aimed to examine the roles and mechanisms of RP in myocardial ischemia‑reperfusion (MI/R) injury of rat cardiomyocytes. Cell viability, reactive oxygen species, mitochondrial membrane potential (MMP) and cell apoptosis were examined by a Cell Counting Kit‑8 assay...
