Abstract:

The assignment of NMR resonances of lupane triterpenoids was refined by the example of 3,28-dinicotinoylbetulin, obtained by acylation of betulin. Hepatoprotective, untiulcer, 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.
