3-Epiursolic acid may have antiinflammatory activity, it shows inhibition on Cathepsins L (catL), the IC50 value of 6.5 μM, cathepsins L (catL) and B play an important role in tumor progression and have been considered promising therapeutic targets in the development of novel anticancer agents.

Somatostatin (GHIH), a peptide hormone, regulates the endocrine system and affects neural transmission and cell proliferation by interacting with G-protein-coupled somatostatin receptors and inhibiting the release of multiple secondary hormones. Somatostatin inhibits secretion of insulin and glucagon.
