Biochem/physiol Actions

Leonurine (SCM-198) is a natural product with antioxidant, anti-inflammatory, and cardioprotective activity being investigated for the treatment of cardiovascular disease and stroke. Leonurine suppresses inflammation and oxidative stress, decreasing a number of inflammatory factors, reducing cardiac Nox4 expression, ROS production, NF-KB activation, and plasma MMP-2 activity and increasing superoxide dismutase (SOD).
Leonurine is an antioxidant, anti-inflammatory cardioprotective agent.
