3-Epicorosolic acid has a potent inhibitory effect on Epstein-Barr virus early antigen (EBV-EA) induction. 3-Epicorosolic acid shows both potent α-glucosidase and protein tyrosine phosphatase 1B (PTP1B) inhibitory activities with IC50 values of 30.18 and 4.08 μg/ml respectively. 3. 3-Epicorosolic acid shows mixed type inhibition against PTP1B, while it shows uncompetitive inhibition against α-glucosidase; suggests that it has potential antidiabetic activity. 4. 3-Epicorosolic acid possesses the ability to inhibit the expression of one or more inflammatory genes induced by 12-O-tetradecanoylphorbol-13 acetate in mouse skin, it has potential anti-inflammatory activities as well as cancer chemopreventive activity.

Pygenic acid A is a natural compound that can be found in Prunella vulgaris. Pygenic acid A induces apoptosis in metastatic breast cancer cells. Pygenic acid A can be used for the research of diabetes, inflammatory diseases, and cancers[1].
