Stachydrine, a pyrrolidine betaine, was first isolated from seed husk and the pulp of the fruit of C. Leonurus, and many other Asian plants and fruits. Stachydrine is an anti-metastatic agent. Stachydrine hydrochloride induces apoptosis in MCF-7 and T47D cells and exerts inhibitory effects on proliferation by concurrently suppressing Akt and ERK survival signals, suggesting its potential efficiency in treatment of breast cancer. Stachydrine (Sta) has also been reported to possess numerous cardioprotective effects. It ameliorated pressure overload-induced diastolic heart failure by suppressing myocardial fibrosis.
