Hepatoprotective, antiulcer, antiinflammatory, reparative, and anti-HIV activities were found for the compound. In addition, it was demonstrated to have immunomodulatory activity, for the first time detected among lupane triterpenoids UR - https://drive.google.com/file/d/1Ifkph1heqfpwcqYhbV_zpGF2w0iXK-iX/view?usp=drivesdk ER -
