Abstract:The assignment of NMR resonances of lupane triterpenoids was refined by the example of 3O,28O-dinicotinoylbetulin, obtained by acylation of betulin. 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.
Keywords:betulin dinicotinate  hepatoprotective  immunomodulatory  antiulcer  anti-HIV activities  lupane triterpenoids
